COUTH MC 2000T²
Instruction Manual
1. INTRODUCTION
The MC 2000T² controller is the electronic system that monitors the movements of a marking
head (stylus) according to a user-defined marking program.
Editing the marking program is generally done using the MC 2000T² controller itself, although
the program can be externally prepared and transmitted to the controller later by means of an
SD memory card or through a serial communications interface.
The MC 2000T² controller has several operation interfaces that permit manual or automatic –
PC or PLC driven – operation, which makes it ideal equipment for incorporation into production
lines that perform various processes other than marking.

To install the MC 2000T² controller correctly, do the following:
1. With the controller off, plug the male cable from the marking unit into the MARK-labelled
connector at the back of the MC 2000T² controller.
2. If supplied together with the MC 2000T² controller, connect the start/stop push box to
the MAN-labelled connector at the back of the controller.
3. Plug the power cable into the MC2000T controller. To do this
a. first connect the power cable to the MC 2000T² controller; and
b. then plug the power cable into a mains outlet.
Before making any connection, check that power supply at intake conforms to the MC
2000T² controller power rating specified on the back plate.
4. Switch MC 2000T² controller on.

4. MARKING FEATURES
Before starting to use the MC 2000T² controller, it is essential for you to know the features that
define each marking. This will make it easier for you to set up the adequate parameters in order
to get the expected marking result.
·
Marking Contents: A mark is first defined by what you want to mark. With the MC
2000T² controller, you will be able to mark all the characters of the Latin alphabet
(including accents, diaeresis, etc.) in both small and capital letters. In addition to
alphanumerical characters, you can insert special symbols or logotypes (e.g. your
company's logo) and DataMatrix2 codes in the marking contents. The next picture
shows a mark comprising a mix of alphanumerical text, logo and DataMatrix code.
Picture 3 – Text combined with logotype and DataMatrix code
When defining the marking contents, you can finally insert changeable objects such as
the current date, a serial number that automatically increases after each marking, or a
different character for each shift.
·
Font: This is the second feature used to define a marking. The MC 2000T² controller
permits applying different fonts to the same marking contents. The picture below shows
the same text to be marked using two different fonts.
Picture 4 – Text marked using different fonts
·
Character Height: Character height is stated in mm and, as its name suggests, it
determines the final height of a (capitalised) character. When small letters are to be
2
A DataMatrix code is a two-dimensional symbol used to insert a large amount of information in a small
space. It is similar to a bar code, except that information is encoded using dots instead of bars, which
allows for a higher density of information.

Controller
marked, the final height will be in proportion to the upper case letters. Below is a picture
showing the same text with different character heights.
Picture 5 – Text with different character heights
·
Character Width: The character width is stated as a percentage (%) of the character
height. Its value normally is 100%, meaning that the character to be marked will keep
the proportion of width to height as defined by the font design. However, it may be
suitable to reduce the character width (programming a value less than 100%) under
certain circumstances (e.g. limited space on the substrate or for aesthetical reasons).
Likewise, it is possible to specify a character width greater than 100% of height. The
next picture shows the same text with different character widths.
Picture 6 – Text with different character widths
·
Character Spacing: This too is given as a percentage (%) of the character height and it
defines the size of space between two consecutive characters. The picture below
shows the same text with different character spacings.
Picture 7 – Text with different character spacings
·
Marking Dots Density: Marking dots density is stated as a percentage (%) of a
continuous marking pattern (without space between two consecutive dots) and it
defines the number of marking dots per unit length. Below is a picture showing the
same text with different marking dots densities.

COUTH MC 2000T²
Instruction Manual
Picture 8 – Text with different marking dots densities
·
Marking Coordinates: The above described features determine the appearance of a
mark. Marking coordinates establish the marking position within the machine's marking
area. The marking zero point or origin (coordinates 0,0) lies in the upper left corner of
the marking area, with the X-axis extending to the right and the Y-axis to the bottom. If
we program marking coordinates x,y for a text, we mean that the lower left end of the
first character shall lie at coordinates x,y.
The next picture shows a marking area that is 90mm wide (X-axis) by 60mm high (Yaxis) and the marking coordinates for various texts.
Picture 9 – Coordinates of a marking area
·
Marking Direction: This refers to the possibility of marking a text horizontally, obliquely
at any angle, or forming a convex or concave arc. The MC 2000 T² controller further

Controller
permits both horizontal and vertical mirror-symmetric marking. Below there is a sample
of markings made in various directions.
Picture 10 – Marking in various directions
·
Marking Depth: With the MC 2000 T² controller it is possible to adjust the marking
force within certain limits, although the marking depth largely depends on the type of
machine used to mark.

show:
Picture 14 – Menu Screen and Parameters Screen
Turn the rotary pushbutton to select another line; press the rotary button to retrieve the selected
screen from a menu screen or to edit the selected parameter from a parameters screen.
Editing a parameter is possible in a number of ways according to its type:
·
Editable Alphanumeric Parameters: These are parameters having an alphanumeric
value that the operator can edit. One example of such parameters is the character
height. If you press the rotary pushbutton, a blinking cursor appears under the first
editable character of the parameter.
Cursor
Picture 15 – Editable alphanumeric parameter
It is also possible to edit this type of parameters by pressing the alphanumeric keyboard
after selecting the line, without need for pressing the rotary pushbutton previously.
Rev. A– Nov 2007

With the alphanumeric keyboard, you can change the value of the parameter and move
the cursor by turning the rotary pushbutton.
When you have finished editing the parameter, press the rotary pushbutton once to
confirm the entry and return to the initial situation of the screen with the selected line.
Alternatively, you can press ESC instead of pressing the rotary pushbutton in order to
exit the Edit Parameter mode without confirming any changes.
·
Parameters with values from a closed list: These are parameters that can only take
any of the values recorded in a closed list. One example of such parameters is the
counter Reset. When you press the rotary pushbutton, a window with the selectable
values pops up.
Picture 16 – Parameter with values from a closed list
Turn the rotary pushbutton to select the required parameter value. Press on the rotary
pushbutton once to confirm the entry, exit the edit mode and return to the initial
situation. Alternatively, instead of pressing the rotary pushbutton, you can press the
ESC key in order to exit the edit mode without confirming any change to the existing
parameter value.
·
YES/NO Parameters: These parameters take either of two values only. When you
press the rotary pushbutton, the value of the selected parameter changes, i.e. if it was
YES it changes to NO, and vice versa.
In order to quit a menu or parameters screen, you can press any of the short-cut keys or the
ESC key. In the event of the parameters screens, if you press ESC and had previously changed
the value of any parameter, the MC 2000T² controller will prompt you to confirm whether you
want to save the changes or not.

5.2.3. Overlapping Windows
If you press any of the short-cut keys F4, F5 or F6 from the EDITION screen, a window overlaps
this screen and shows some of the current file's marking properties. To be exact, there are three
overlapping windows that show the following marking properties:
·
·
·
FONT overlapping window: it shows the values of the character height, character
width, font type, character spacing and marking dot density.
FORCE & SPEED overlapping window: this shows the values of the marking force
and speed.
POSITION & SHAPE overlapping window: it shows the values of the X-axis
coordinate, Y-axis coordinate, marking angle, arc diameter, arc type, horizontal mirrorsymmetric marking and vertical mirror-symmetric marking.
In these windows, there is always one active line that is highlighted as Picture 20 shows. This
line states the marking properties of the associated text line. On said picture, the value of all the
parameters is ‘-‘, meaning that the value of the selected parameter is identical to that of the
same parameter in the preceding line. As for the first line, the value of the parameter is the
default value as defined from the EDITION PARAMETERS screen.

Picture 22 – Editing a parameter in an overlapping window
Like the parameters screens, this window provides two ways of editing the parameters
depending on its type:
·
Editable numerical parameters: You can enter the parameter value typing it directly
on the numeric keypad. The blinking cursor moves at each keystroke, showing the digit
you may change.
Turning the rotary pushbutton increases or decreases the parameter value in one
parameter definition unit. Taking the character height stated in mm with one decimal
digit, for example, if you turn the rotary pushbutton clockwise, the parameter value will
increase in 0.1mm. If the parameter value is "-" before turning the rotary pushbutton, it
will change to the minimum value for the parameter concerned, which is 0.1mm in the
case of the character height.
If you continue turning the rotary pushbutton to change the value of the selected
parameter, the blinking cursor will relocate itself under the first digit of the parameter
value.

same way as parameters with values from a closed list, since those parameters can
take the value "-" in addition to the YES and NO options.
Editing those parameters is very simple: you just need to turn the rotary pushbutton in
one direction or the other in order to select the next or previous value from those
available.
Picture 24 – Parameter with value from a closed list in an overlapping window
After editing one parameter, press the rotary pushbutton once to confirm the entry and return to
the situation as per Picture 21, in which you can select another parameter in the same line by
turning the rotary pushbutton. Instead of pressing the rotary pushbutton, you can press ESC to
return to the a.m. situation, but without confirming the entry.
Finally, after editing all the parameters, press the rotary pushbutton for a long while in order to
close the overlapping window, return to the EDITION screen and save all changes made.
Alternatively, you can press any short-cut key or ESC to confirm the changes made and move
to the appropriate screen.

6. MARKING EXAMPLES
This section contains a number of marking examples. These simplified examples highlight the
most frequently used characteristics of the controller and thus provide rapid and easy training in
producing the commonest types of marks.
In developing all the examples, we used a marking unit with a marking area of 50mm (X-axis)
by 17mm (Y-axis), which presently is the COUTH marking unit having the smaller marking area.
Therefore, all the examples given in this section can be produced with any other COUTH
marking unit. In this event, there is one point to bear in mind: when reproducing the examples
with any marking unit having a different marking unit, the aspect of the scale simulation will
differ from the look it has in this manual.
Likewise, it is important to consider the default values of the marking parameters used. For the
examples given, we used the following parameter values:
·
·
Height: 005.5
Width: 100
·
·
·
·
·
Font: GULIM.FNT
Spacing: 25%
Density: Auto
X-axis coordinate: 000.0
Y-axis coordinate: 000.0
·
·
·
·
·
Angle: 000.0
Diameter: 000.0
Concave/Convex: ^
Horizontal mirror: No
Vertical mirror: No
·
·
·
·
Speed: 10
Force: 10
Selfcentering(x): NO
Selfcentering(y): NO
If your controller has values differing3 from the above, we recommend you to change them in
the EDITION PARAMETERS screen; otherwise, the examples you work out may look quite
different from those shown here.

If you are using your MC 2000T² controller for the first time or if you never changed the parameters in
the EDITION PARAMETERS screen, the default values of the parameters will be those specified here.

6.1. Simple Marking
To start with, let's make a very simple marking. Its result will look like this:
The first time you power on the MC 2000T² controller, the display will show the HOME PAGE
screen and then a TEST screen, followed by the EDITION screen with the blinking cursor in the
first column of the first line.
If you have already used the controller and the display shows any screen other than the
EDITION screen, call it up (press the direct access key F1 to retrieve the MAIN menu from any
screen and then press F1 again).
In the EDITION screen, type out the text HELLO as the next picture shows.
Picture 25 – Editing the text of a Simple Marking example
The marking unit is ready to mark and does not require editing any other marking parameter,
since it will use the default values.
Before starting the marking unit, press the Simulation key to preview the resultant mark. The
display will show the dry test result that will look like this:

At the end of the dry test, the MC 2000T² controller displays the EDITION screen again. If you
are ready to do the marking operation, press the Start pushbutton.
6.2. File Management
This example aims at saving the job of the previous example in a file for future use. Additionally,
we are going to create a new file in order to do the next exercise starting from nothing.
After making a marking successfully, you might wish to save it in a file for future use. From the
EDITION screen, press the direct access key F3 to retrieve the FILES screen that allows you to
manage files. After opening this screen, press the direct access key F4 to save a file. As you
can see on the picture below, the display shows a new filename 00000000.TXT with a blinking
cursor under the first character.
Picture 27 – File saving
Use the alphanumeric keyboard to rename the file as you wish and press the rotary pushbutton.
In order to work with this file later on, press the direct access key F3 to open it and return to the
EDITION screen.

To complete this exercise, press the direct access key F2 in the FILES screen to return to the
EDITION screen with a new empty file.
6.3. Marking Several Lines
This exercise consists in making a marking similar to the simple marking of the first example,
but writing the text on two lines. The result will look like this:
In the EDITION screen, starting from a new file, type out the text HELLO WORLD on two lines.
Changing from one line to another is achieved by shortly pressing the rotary pushbutton to
highlight the selected line, moving the cursor to the next line by turning the rotary pushbutton
and pressing the rotary pushbutton again to be able to edit the text on the second line.
Picture 28 – Editing a sample text on various lines
There is no need for changing any other parameters, in order to mark the two-line text, since the
MC 2000T² marking unit automatically moves the second line vertically so that marking does not
coincide with that of the first line.
Press the Simulation key to preview the result, as shown on the next picture.

6.4. Marking Special Characters
In this exercise, we shall mark the text of the previous example, written in small letters and with
special characters added. The result should be like this:
In the previous examples, the text was fully written in capital letters, using the visible characters
of the alphanumeric keyboard. In order to write the text with a mix of capital and small letters,
press the shift key to change from one type to the other. On doing so, you can see the letter
icon in the middle of the general information field showing alternately a capital and a small letter
"a".

On the other hand, to insert characters that do not appear on the keyboard of the MC 2000T²
controller, press the special symbol key to open an overlapping window allowing you to choose
and insert the desired character.
The MC 2000T² controller permits the use of the entire Latin set of characters as specified by
ISO-8859-1.
Picture 31 – Special symbol window overlapping the EDITION screen
Turn the rotary pushbutton to select the desired characters and finish writing the text Hello
World! on two separate lines.
6.5. Changing the Marking Parameters
This example serves to apply different marking parameters to different characters. Here is the
expected result:
In the two previous examples, we have used two file lines in order to mark the text on two
different lines. The "file line" concept is however broader than that of a text line. As the result of
this exercise shows, three words will be marked on a same text line: the character height and
width being respectively 5mm and 100% for the first word; 2.5mm and 100% for the second
word, and 2.5mm and 50% for the third word.
Whereas those three words will be marked on a single text line, it is not possible to use only one
file line for this purpose, because their marking parameters differ and a file line only accepts
characters having the same marking parameters. Therefore, three file lines are necessary to do
this exercise.
As a rule, whenever any part of the marking contents requires a different marking parameter,
you will need to enter this part of the contents in a new file line. In the previous examples
"Marking on several lines" and "Marking of special characters", the Y-axis coordinate was the
parameter that determined the change of line.
Understanding this principle makes working out the last example easy.
PAGE - 30
Rev. A – Nov 2007
COUTH MC 2000T²
Instruction Manual
MC 2000 T²
Controller
Starting from a new file, write the words HELLO, LITTLE and WORLD on three successive file
lines. Next, set the parameters for the second line as follows:
·
Character height: 02.5
·
·
X-axis coordinate: 023.0
Y-axis coordinate: 005.0
and set the parameters for the third lines as follows:
·
Character width:: 050
·
·
X-axis coordinate: 035.0
Y-axis coordinate: 005.0
You will have noticed that it has been necessary to specify appropriate marking coordinates for
these two lines. Programming correct values involves trying approximate values and adjusting
them, using the simulation function until the result is satisfactory.
6.6. Angle Marking
Angle marking at an angle of 45º is the subject of this example. The result will look like this::
To mark a text at any angle, bear in mind that the X-axis coordinate for the first line of text to be
marked (in this example, the line containing the word HELLO) will probably be different from
zero. This is because, in order to reach the required inclination, the text pivots on the lower left
corner of the first character part of which thus lies to the left of said corner. A similar rule applies
to the Y-axis coordinate. In this event, it is more obvious, since the text must be moved
downwards to avoid getting out of the marking margins.
Thus, after writing the text HELLO WORLD on two lines, change the values of the X-axis
coordinate, Y-axis coordinate and angle of the first line, as follows:
·
·
·
X-axis coordinate: 005.0 mm.
Y-axis coordinate: 012.0 mm.
Angle: 45º.
Rev. A – Nov 2007

COUTH MC 2000T²
Instruction Manual
Now, if you press the Simulation key, you will see that part of the marking is outside the marking
margins, because the font size is too large. Therefore, change the character height for the first
line:
·
Height: 02.0 mm.
Press the Simulation key to preview the result that will look like that shown on Picture 32.
Picture 32 – Preview of angle marking
As you can see, the text on the second line is angled too. If you do not want this text to be
marked obliquely, you need to set the angle value for this line at zero.
Finally, try changing the angle value and watch the new inclination of the text.
6.7. Arc Marking
This example explains how to make a concave marking and a convex marking. The result looks
like this:
Arc marking with the MC 2000T² controller is easy, provided the arc marking underlying
concepts are absolutely clear.

Concave/convex: Convex arc means an arc so formed that the text on the whole
circumference is readable from the inside of the arc. By contrast, a concave arc is that
which permits you to read the text on the whole circumference looking at it from the
outside of the circle.
Picture 33 – Convex arc and concave arc.
The above picture shows a convex arc on the left and a concave arc on the right.
·
Diameter: This refers to the diameter of the circle on which the text is marked. The arc
radius is always measured from the centre of the circle to the lower left corner of the
first character. Shown below are the radii of a convex arc and a concave arc.
Picture 34 – Arc radii
·
Angle: This defines the angular position of the first character in relation to the
horizontal. The next picture shows 8 arc markings at 8 different angles.
Rev. A – Nov 2007
PAGE - 33
MC 2000 T²
Controller
COUTH MC 2000T²
Instruction Manual
Picture 35 – Angles of arc markings
To work out the suggested example, follow these step-by-step instructions and press the
Simulation key after each operation to check its effect:
1. Write CONVEX ARC on the first line of a new file and CONCAVE ARC on the second
line.
2. Set the Character Height parameter for the first line at 2mm.
3. Change the first line marking coordinates as follows: X = 5mm and Y = 8mm.
4. Change the second line marking coordinates as follows: X = 4mm and Y = 10mm.
5. Change the Convex/Concave parameter, assigning "convex" to the first line and
"concave" to the second line.
6. Enter 20mm as the Diameter value for the first line and 24mm for the second line. The
reason for entering different values is that the above mentioned definition of "diameter"
makes it necessary to add twice the character height to the convex arc diameter in
order to get two circles of "same diameter". If you press the Simulation key at this stage,
the marking may exceed the marking margins, depending on the marking area of your
marking unit. Do not worry; this will be corrected with the next step.
7. Change the arc angles, specifying 53.0º for the first line and 310.0º for the second line.
Press the Simulation key and you will get the expected result.
The values entered at this final step are not easily deducible from the marking result shown at
the beginning of the exercise. An efficient method to determine those values is through trial and
error: starting from an angle value of 0º, increase this value and check the result after each
change with the Simulation key. Three or four trials should be enough to assess the adequate
values for the marking concerned.
6.8. Marking Special Functions
This example aims to marking special time and counter data. Its results will look like this:
PAGE - 34
Rev. A – Nov 2007
COUTH MC 2000T²
Instruction Manual
MC 2000 T²
Controller
In the EDITION screen, write TIME on the first line of a new file. Next, insert the special mark
"Calendar:Hour-Minutes". To do so, press short-cut key F2 on the EDITION screen; this opens
the INSERT screen. Now press F2 again to open an overlapping window with the available
"Calendar" options. Select the aforementioned one with the rotary pushbutton.
On the second line, insert the special mark "Counter:C1". To do so, press short-cut key F2 on
the EDITION screen; this opens the INSERT screen. Now press short-cut key F4; this opens an
overlapping window with the available Counter options. Select the aforementioned one (Counter
1) with the rotary pushbutton. The EDITION screen will be like this:
Picture 36 – Editing special functions
As you can see, the counter value is 0000000000. If you press the Start button, the counter
value will not increase automatically after finishing the marking. The counter increases only
when making the marking from the MARKING screen. Save the edited file, open the MARKING
screen and mark the file several times. As you will notice, the value of the counter automatically
increases after each marking.
6.9. DataMatrix Marking
This example aims to marking two DataMatrix codes and the encrypted text they contain. It will
give the following result:
Rev. A – Nov 2007
PAGE - 35
MC 2000 T²
Controller
COUTH MC 2000T²
Instruction Manual
On the first line of a new file, insert the special "Square DataMatrix " mark and write HELLO in
the parenthesis of this special mark. To insert the DataMatrix square mark, press short-cut key
F2 to open the INSERT screen; next press short-cut key F6 and select the "Square DataMatrix"
from the available options.
To place the cursor inside the parenthesis, first move back to the beginning of the special mark
and next move it one position forward. After writing the text to be encrypted, move the cursor
one position forward by turning the rotary pushbutton, leave a blank space behind the special
DataMatrix mark and type out HELLO.
On the second line, insert a special "Rectangular DataMatrix " mark and, instead of writing a
certain text inside, insert a special mark "Calendar:year-month-day". Move the cursor out of the
special DataMatrix mark and insert a blank space and the same special Calendar mark. The
EDITION screen should look like this:
Picture 37 – Editing DataMatrix codes
Finally, change the character height for the first line to 3.5mm (to prevent the mark from
exceeding the marking margins when using marking units with a small marking area). You can
also change the value of the Y-axis coordinate for the second line in order to separate the
DataMatrix codes and thus to be able to distinguish them easier. Setting the value of this Y-axis
coordinate to 010.0 will be appropriate.
Having made a simulation or marking, you will notice that the height of each DataMatrix code
coincides with the specified character height. Try inserting a bigger text inside the special
DataMatrix marks and you will see that the overall size remains identical to the character height
although the new codes are denser (greater number of rows and columns).
If you have a DataMatrix code reader, you will further observe that the coded text coincides with
the text entered (as regards the rectangular DataMatrix code of the example, the text will be the
current date).

6.10. Logotype Marking
In this example, we are going to mark two logotypes and a fixed text. The result will look like
this:
Like the DataMatrix codes in the previous example, a logotype is processed in the same way as
any other text character. In this example, we are going to mark a logotype inserted at the end of
a text and the same logotype on a different file line in order to increase its size.
On the first line of a new file, write COUTH and insert the special logotype mark for the desired
logotype (in our example CE.LOG). To insert the special logotype mark, press short-cut key F2
to open the INSERT screen; next press short-cut key F3, select LOGOTYPE and choose the
desired logo from the list.
On the next line, insert only the same special logotype mark. The text editing screen should look
like this (if you entered another logo, its name will appear instead of CE.LOG):
Picture 38 – Editing logotypes
Next, change the character height for the first line, setting 3.5mm. Set the character height for
the second line to 10.0mm.
After effectively marking this file, you will see that, as commented above, the logo on the first
line has been processed just like any other character.

Please bear in mind that the screen always shows the counter's ten digits, even if you specified
a smaller number of markable digits in the counter's setup parameters. In this event, the digits
that shall not be marked may take any value, since the MC 2000T² controller will omit them.
It is the EDITION screen's function to enable you to set the marking parameters until you
get the expected result. Once you have achieved this, you must save the file and retrieve the
MARKING screen to make the final markings. During the parameters setup process, you may
need to perform several marking tests. For this reason, the counters are inoperative in the
EDITION screen; the dry run marking shows the same counter value and there will be no
automatic increment or decrement of the counter value.
7.4.2. DataMatrix Codes
After inserting a special DataMatrix code mark, editing the encryptable text is similar to editing
the counter value: move the cursor inside the parenthesis of the DataMatrix special mark and
type the text you want.

mark have been placed.
7.5. FONT Overlapping Window
This window pops up when pressing short-cut key F4 in the EDITION screen and serves to
change the font parameters for the active file.
Picture 47 – FONT overlapping window
Specifically, the following are the modifiable parameters for each line in the file:
·
·
·
·
·
Character height: Height in mm of the characters, logotypes and DataMatrix codes to
be marked. The maximum character height is the Y-axis travel of the machine.
Character width: Width stated as a percentage (%) of the height of the characters,
logotypes and DataMatrix codes to be marked. You can specify width equal to 100%
height, less than 100% (compression) or greater than 100% (expansion).
Font: Font in which the text will be marked.
Character spacing: Spacing between two consecutive characters, stated as a
percentage (%) of character height. It is possible to define spacing characters of up to
200%.
Dot marking density: Number of dots to be marked, in %. A dot marking density of
100% denotes continuous marking (5 dots per mm). You can also select the value Auto
for high marking density at high speed when using the autovibrating pneumatic head.
7.6. FORCE & SPEED Overlapping Window
This window pops up when pressing short-cut key F5 in the EDITION screen and serves to
change the marking force and speed parameters for the active file.

Instruction Manual
Picture 48 – FORCE & SPEED overlapping window
Depending on the use of a pneumatic or electric (solenoid) marking head, the Force parameter
will be interpreted in different ways.
·
·
Pneumatic Head: When the setting of the marking density is Auto, the system
disregards the Force parameter. Otherwise, with force settings from 1 to 3, the
stylus impacts the workpiece only once per marking dot; with force settings from 4
to 6, there will be two impacts of the stylus per dot; with force settings from 7 to 10,
there will be three impacts of the stylus per dot.
Electric Head: In this case, the solenoid excitation time varies according to each
force value, resulting in stronger or weaker impacts. However, for effective results, it
is necessary to adjust the stylus-to-piece distance for each force setting. The table
below shows adequate distances for different forces:
Force

The Speed parameter, too, is interpreted differently according to the type of marking head.
When using an electric head, this parameter has no effect. If the marking head is pneumatic,
this parameter is meaningful only when the marking density setting is Auto. In this event, the
lower the speed, the greater the marking density, resulting in higher quality marks to the
detriment of the marking time.

7.7. POSITION & SHAPE Overlapping Window
This window pops up when pressing short-cut key F6 in the EDITION screen and serves to
change the position and shape parameters for the active file.

X-axis coordinate: Position of the lower left corner of the first text character along the
X-axis. Changing this parameter's value, by turning the rotary pushbutton, results in a
movement of the marking head to the specified coordinate. This is very useful to check
the marking coordinate on the workpiece in the marking position.
Y-axis coordinate: Position of the lower left corner of the first text character along the
Y-axis. As this occurs with the X-axis Coordinate parameter, by changing the
parameter's value with the rotary pushbutton, the marking head will move to the
specified coordinate. If you select value "-" for any line other than the first line, this line
will not take the value of the previous line, but its value will be automatically increased
by the character height to prevent superimposing the texts of two lines.
Angle: This is the text inclination angle as measured from a horizontal line. Picture 50
shows 5 text lines marked at angles of 0º, 45º, 90º, 180º and 270º.

You can easily recognise a special mark, since it appears in bracket-like symbols:
The following Insert options are available:
·
F1 – Insert Shift: Inserts a special mark for marking the relevant shift in the marking
contents. Actual marking will replace the special mark with the identifier of the current
shift. In the SHIFTS window retrievable from the CONTROLLER PARAMETERS
screen, you can define up to four shifts with one marking identifier for each.
·
F2 – Insert Calendar: This function opens a window allowing you to select the temporal
data you want to insert in the contents. Actual marking will replace this special mark
with the relevant data. These are the selectable temporal data:
- Hour (hh)
- Minutes (mm)
- Hour-Minutes (hh-mm)
- Day of the week (d)
- Day of the month (dd)

F4 – Insert Counter: This function allows you to insert a special mark relating to one of
the two independent counts available per file. A counter is a number made up of one to
ten digits, which increases or decreases automatically after a user-definable number of
markings have been reached. The parameters that define the performance of each
counter are modifiable in the COUNTERS screen accessible from the CONTROLLER
PARAMETERS screen.
·
F5 – Insert Movement: This function opens a window that permits inserting a
Movement. During actual marking, on reading this mark, the controller performs the
related action or movement. These are the selectable Commands:
- Wait for signal: The MC 2000T² controller will wait for an input signal to its
MARK or AUTOMAT Input connector before proceeding with the marking
operation. For its detection by the MC 2000T² controller, this input signal must
be +24VDC or –24VDC. Inputs to the MARK connector are reserved for special
applications developed by COUTH. Signals to the AUTOMAT Input connector
are allocated as follows: signal 1 to the connector's terminal 1; signal 2 to
terminal 2, signal 3 to terminal 3. The voltage value of all those signals refers to
terminal 12 of said connector.
When 24VDC signals are not available, but potential-free signals (relays) are
used, the 24VDC voltage can be obtained from terminals 13 and 14 of the
AUTOMAT Output connector.
This command is useful to avoid starting the marking (or part of it) unless an
external item is ready and this item sends the confirming signal to the controller.
- Line Origin Coordinate: The marking head moves to the origin coordinate of the
line that contains the command, before marking continues. This command
serves to force the marking head to follow a certain path before or after a
marking in such cases where the workpiece presents an obstacle the marking
head must overcome. It is possible to insert several commands of this type in
different lines of a file in order to achieve complex markings. A line containing
this command will usually include nothing else.
- Wait for communications: The MC 2000T² controller wait for the marking
contents (or part of it) to be transmitted through the RS232 serial interface. It is
possible to connect port COM 2 to a barcode reader or port COM 1 to an
automaton, PC or PLC.
- Activate output: Before proceeding with the marking, the MC 2000T² controller
will activate one of the available outputs of the MARK or AUTOMAT Output
connector. These are potential-free signals (relays). The outputs of the MARK
connector are reserved for special applications developed by COUTH. Signals
from the AUTOMAT Output connector are allocated as follows: output 1 relates
to terminals Q1 of said connector; output 2 to terminals Q2; output 3 to
terminals Q3; output 4 to terminals Q4.
If 24VDC instead of potential-free signals are needed, those 24VDC signals can
be obtained from terminals 13 and 14 of the AUTOMAT Output connector.
This command is useful to actuate an external item (through a electric valve, for
instance) before starting or proceeding with a marking.
- Deactivate output: Before proceeding with the marking, the MC 2000T²
controller will deactivate one of the available outputs of the MARK or
AUTOMAT Output connector.
This command serves to deactivate an output that has been previously
activated by inserting the "Activate output" command. In any case, all the
outputs are automatically deactivated at the end of the marking process.

existing timers is done in the TIMERS screen accessible from the
CONTROLLER PARAMETERS screen.
This command is useful to avoid starting the marking (or part of it) unless an
external item is ready and this item can’t send the confirming signal to the
controller. For this purpose, it is necessary to define the maximum time this item
will take to be ready, from the moment it starts actuating till it finishes its job,
and to program this time in a timer. It is however safer to wait for an external
signal than a set time; therefore we recommend inserting the command "Wait
for signal" whenever possible.
Plate Feeder: This command instructs the MC 2000T² controller that a COUTH
plate feeder has been fitted and must be coordinated with the marking process.
F6 – Insert codification: With this function, you can insert a special mark for
generating a square or rectangular DataMatrix code. After inserting the special mark,
you can edit the text to be encrypted, by moving the cursor in the parenthesis that the
DataMatrix special mark contains. It is also possible to insert other special marks (such
as the current date or a serial number, if they are to be encrypted in the DataMatrix
code) within the DataMatrix special mark.

Reset specifies whether the marking contents must be deleted after marking, when the
controller operates as a slave (controlled by an automaton, PLC or computer). This would avoid
marking the same contents more than once, in order to guarantee, for instance, that a
computer-defined serial number will not be marked on different parts.

For the MC 2000T² controller to recognise the Reset parameter, it is essential to program the
operating mode: slave or file. This is done setting the Marking Mode parameter. Besides, when
selecting the slave operating mode, it will not be possible to select the file manually in the
MARKING screen nor use the internal Start and Stop pushbuttons.
It is worth noting that the MC 2000T² marking machine can work in a slave condition at
any time, even when the Marking Mode parameter specifies the file mode of operation. This
parameter is taken into account only for the purposes of using the Reset parameter.
7.21. EDITION PARAMETERS Screen
To open this screen, select option 4 – EDITION PARAMETERS in the PARAMETERS screen. It
permits you to change the marking parameters to be used by default in the EDITION screen.
Picture 70 – EDITION PARAMETERS screen
If you do not enter a value for any of the parameters in the FONT, FORCE & SPEED or
POSITION & SHAPE overlapping window, the system will use the value set through this screen.
Programming default values is particularly useful when most of the files require using the same
value for one or several parameters, since you enter them only in this screen instead of setting
them separately in all and any of those files. Then, you only set values in the files that need a
different value.
In addition to the parameters of the a.m. overlapping windows, it is possible to set another two
parameters: Selfcentering (x) and Selfcentering (y). Both parameters are usable with any
COUTH marking machine, but they are specially intended for portable machines, since they
ensure automatic centring of the marking contents along the X-axis or the Y-axis inside the
marking area. The next picture shows the result of marking with the X and Y self-centring
options enabled in a 50mm x 17mm area.
The self-centring options are disabled when the marking parameters specify marking

Parameters Date and Hour serve to set the current date and time.
Parameter Automatic hour change instructs the controller to change or not summer time and
winter time automatically, if desired. When entering the "European" time changeover, the clock
will go forward from 2 a.m. to 3 a.m. on the last Sunday of March and backward from 3 a.m. to 2
a.m. on the last Sunday of October.
Parameters Week day, Month and Month day serve to define the characters to be marked
instead of the special marks Day of the Week, Month of the Year and Day of the Month,
respectively. You can select a different character for each day of the week (bearing in mind that
Monday is the first day of the week), for each month of the year and for each day of the month.
If you select no character, the system inserts a hyphen and the marking machine will mark the
number of the day or month instead of the special mark.
Finally, with parameter Separating character you can define the character that separates the
different constituents of a special mark, such as the Day-Month-Year special mark. This
character shall be marked between the characters standing for the day and month and between
those standing for the month and year.
7.25. COUNTERS Screen

Controller
COUTH MC 2000T²
Instruction Manual
Picture 75 – COUNTERS Screen
A counter is a 1 to 10 digit number that increases (or decreases) automatically after a preset
number of markings. With the MC 2000T² controller, there are two counters available and
although their parameters are identical, the value of each counter is saved independently with
each file. This means that, if counter 1 were used in two files, the value of counter 1 can be,
say, 1111 in the first file and, say, 2222 in the second file.
These are the parameters underpinning the performance of each counter:
· Increase: This is a value ranging from –100 to +100 that specifies the amount by which
the counter value increases. To change from a positive to a negative value, or vice
versa, just press any key when the cursor is under the + or – sign.
· Repetition: This setting that can take any value from 0 to 100 indicates the number of
times the counter value must be repeated (in addition to the initial marking) before this
counter increases or decreases automatically. Setting 0 implies that there is no
repetition of the marking and, therefore, after the machine has marked the counter
value once, the counter changes to its next value; setting 8, for instance, implies that
the marking will be repeated 8 times; thus, the machine will mark the same counter
value 9 times, before the counter increases or decreases.
· Digit number: Indicates the number of digits to be marked. If the counter value has
fewer digits than those to be marked as specified here, the machine will add zeros to
the left.
· Minimum and Maximum: These parameters specify the minimum and maximum
permissible values of the counter. On reaching the maximum (high) value, a counter
with a positive increment will restart from its minimum (low) value. By contrast, on
reaching the minimum (low) value, a counter with a negative increment will restart
decrementing from its maximum (high) value.
·
Reset: This parameter serves to specify a condition under which the counter with a
positive increment shall reset to its low value and a counter with a negative increment
will reset to its high value. The following options are programmable:
- None: No condition is established.
- Year: The counter resets when year changes.
- Month: The counter resets when the month changes.
- Week: The counter resets when the week changes, considering Monday as the first
day of the week.
- Day: The counter resets when the day changes. .
- Shift: The counter resets at each shift changeover.

7.26. COMMUNICATIONS Screen
This screen is accessible by selecting option 4 –COMMUNICATIONS in the CONTROLLER
PARAMETERS screen. It enables you to change the parameters that define communications
with the MC 2000T² controller through the RS232 serial interface.
Picture 76 – COMMUNICATIONS Screen
Parameter Baudrate defines the transmission rate in bits per second between the controller
and the external equipment communicating with it.
Parameter Protocol defines the communications protocol to be used. We recommend using the
MC 2000T² protocol, since it permits making the most of all the features of the MC 2000T²
controller. Other usable protocols are MC 2000T and MC 2000L, but these protocols should be
used only when the MC 2000T² controller shall operate jointly with an MC 2000T or MC2000L
controller that already use one of these two protocols.
Parameter Error checking defines the type of error detecting algorithm to be included in the
communications. COUTH recommends using always CRC because it provides serial
communications with greater security.
Parameter Topology specifies whether the external equipment (automaton, PLC or computer)
communicates only with this controller (point to point topology) or will communicate with several
MC2000T² controllers at the same time (network topology). In this latter case, the controller will
stop using asynchronous transmission for some messages in order to avoid possible collision
with messages sent by other controllers.
Finally, parameter Address defines a unique communication address for the controller in order
to identify it unequivocally when there are several networked controllers.
7.27. STATISTICS Screen

8. BARCODE READERS
The MC 2000T² controller makes it possible to use barcode or 2D-code readers in order to edit
the marking contents. This avoids mistakes that editing the marking contents manually might
cause.
8.1. Connection
For connecting a barcode reader to the MC 2000T² controller, use the RS-232 interface with the
following communications parameters:
·
Baud rate: .............................9600 bits per second.
·
·
·
·
Parity:....................................Odd.
Data bits: ..............................8
Stop bits: ..............................1
Flow control: ........................None.
Barcode readers and other external devices must always be connected to the controller
through the COM2 port at the rear of the controller. The COM1 port is reserved for connecting a
PC, PLC or automaton.
Both COM1 and COM2 ports of the MC 2000T² controllers are prepared for a direct connection
to a PC through direct pin-to-pin cables. Since barcodes readers with an RS-232 interface are
usually designed for direct connection to a PC too, connecting them to the MC 2000T² controller
will require the use of a NULL MODEM type of cable, crossing terminals 2 and 3 at both ends of
the cable.
If in doubt, remember that data transmitted by a barcode reader is received through terminal 3
of the COM2 port of the MC 2000T² controller.
The MC 2000T² controller provides a 5Vdc voltage across terminals 6 and 5 of the COM2 port.
You can use this voltage for powering up barcode readers that operate on a current not greater
than 250mA.
Finally, for the barcode reader to be operative with the MC 2000T² controller, you must
configure it in such a way that it transmits hexadecimal character 10 (decimal 16) prior to the
text string and hexadecimal character 0A (decimal 10) followed by twice the hexadecimal
character 03 (decimal 03) after the text string it reads. By way of example, if 123-456 is the
barcode read by the reader, transmission of the complete string will be as follows:
Hexadecimal
10
31 32 33 2D 34 35 36

8.2. Use
It is currently possible to use a barcode reader with the MC 2000T² controller in either of two
ways:
·
·
EDITION Screen: With the barcode reader connected to the COM2 port of the MC
2000T² controller, scan the barcode and its contents will appear on the line where the
cursor lies at that moment. Any text that might already be on that line will be
overwritten. Scanning a barcode will not affect the text on any other lines that remain
unchanged.
MARKING Screen: To use a barcode reader from the MARKING screen, the file to be
marked must contain a special command: Movement(Wait for communications). This
special command may be placed anywhere in the file, preceded and followed by text.
On receiving the Start order, the MC 2000T² controller will start marking the active file.
On detecting the special command, the MC 2000T² controller will stop the marking
machine until it receives the remaining marking data. At this time, use the barcode
reader connected to the COM2 port to transmit the marking data. The MC 2000T²
controller will resume marking after receiving the contents of the scanned barcode.

9. BINARY IO MARKING
Binary IO marking is one of the operating modes the MC 2000T² controller offers. This mode of
operation – usable from the MARKING screen – permits marking a file selected by means of the
inputs of the AUTOMAT Input connector. To be exact, inputs 4, 5, 6, 7 and 8 are available for
selecting one among 31 files for its marking in this mode. Input 4 is assigned the least
significant bit of the file number, input 8 the most significant bit.
Since the files are identified by a filename, and not by a file number, in the MC 2000T²
controller, the filename must contain a number from 001 to 031 (including zeros on the left) if
this file is to be selected in the binary mode.
Suppose you want to work with two files in binary mode. You can use two numbers from 1 to 31
to identify them. So, you opt for numbers 2 and 28. Therefore, one file must contain the 002
character group in its name, the other the 028 character group. Any of the following filenames
would be valid for this purpose:
FILE_002.TXT, A0020000.TXT, 002ZZZZZ.TXT, ABC002DE.TXT...
FILE_028.TXT, A0280000.TXT, 028ZZZZZ.TXT, ABC028DE.TXT...
Of course, to avoid confusion, neither the 002 nor 028 character group may be present in any
other filename.
Finally, you decide to name your files FILE_002.TXT and FILE_028.TXT.
To mark those files, you should bear in mind that the binary form of number 2 is 00010, while
number 28 is stated 11100.
Accordingly, in order to mark the file FILE_002.TXT, inputs 4, 5, 6, 7 and 8 of the AUTOMAT
Input connector must be given the following values:

1. INTRODUCTION
The MC 2000T² control unit can be connected via RS-232 with a PC or PLC so that it receives
from it the texts to be marked or part of them. This use is handy when some of the data may not
be stored in the memory of the MC 2000T² control unit because it is variable, for example: the
weight of a piece, tolerance, measureme, etc.
This user manual describes the protocol used for communicating with the MC 2000T² control
unit. This is a robust communication protocol, with a very complete set of commands that allows
the computer or PLC have full control over the MC 2000T² control unit. In addition to sending
files or text to be marked, it is possible to set the parameters of the control unit and completely
govern the entire marking process.
We recommend always using the MC 2000T² communication protocol, as it allows capitalize on
all the characteristics of the MC 2000T² control unit. It is also possible to work with the MC
2000T and MC 2000L protocols, but they should be used only in those cases in which you want
to use the MC 2000T² control unit along with MC 2000T or MC2000L control units which already
use one of these two protocols.

3. COMMUNICATION FORMAT
The communication between the MC 2000T² control unit and a computer or PLC meets the RS232 standard. The following are the peculiarities of the MC 2000T² communication protocol.
3.1. Addressing
The most commonly used connection type with the MC 2000T² control unit, either from a
computer or from a PLC, will be a point-to-point connection type, i.e. the computer or PLC
connected to a single MC 2000T² control unit. However, in some cases it may be desirable to
make a bus type connection, so that a single computer or PLC can communicate with several
control units using a single serial port.
It is not recommended to make a bus type connection using directly the serial ports from a
computer or a PLC and several MC 2000T² units. In the case of wanting to govern various MC
2000T² controllers through a single computer or PLC, it is preferable to perform a means
conversion, using for example RS-232 to RS-422 converters, RS-232 to RS-485 converters or
RS-232 to Ethernet converters. Thus, the bus connection actually takes place in a RS-422, RS485 or Ethernet bus, ensuring greater reliability of communications.
In order to make this second type of connection, each of the devices connected to the bus must
have a unique address bus, so that each time the communication takes place only between two
devicess (usually one in master mode - the computer or PLC- and one in slave mode - the
control unit-), despite the fact that there are more devices connected. Therefore, it is possible to
assign to each MC 2000T² control unit a different address from the rest of devices connected to
the bus. The range of valid addresses is as it follows:
•
Address 0: This address will always be assigned to the computer or PLC.
•
Addresses 1 – 250: Addresses valid for the various MC 2000T² control units connected
to the bus.
•
Address 255: Broadcast address. The communication frames addressed to this
address will be answered by any control unit, even if it’s address is another one.
3.2. SEGMENTATION
In communication with the MC 2000T² control unit it is possible to exchange large data blocks.
In order not to limit the maximum size of the blocks of data to exchange, a block segmentation
mechanism is provided, i.e. a big block of data should be divided into several smaller
communication frames. A maximum frame size of 250 bytes has been defined; this size on the
one hand allows doing the majority of the communications with the control using a single frame
for each command, and on the other hand, does not require the use of a wide amount of
memory designed exclusively for communication.
3.3. Frame format
Each communication frame is formed by seven different fields with the following format:
Order

•
LT: Total lenght of the frame.
•
UT: Last frame: a value of 0 in this field indicates that this is the last frame of a data
block. Any value other than 0 indicates missing more frames to complete the block.
•
CMD: Command: indicates the action to perform on the MC 2000T² controller unit or the
response type from it.
•
DATA: Details of each command. Some commands have no data so this field will be
empty.
•
CRC: Error checking filed. CRC value aplied to all bytes of the frame except for the
same CRC.
3.4. Error checking
The MC 2000T² communications protocol allows using three different types of error checking
mechanisms: CRC, Sum or none. COUTH recommends always using CRC because it is the
most secure and reliable method when it comes to identifying possible errors. If it is not possible
to use this mechanism, it is recommended to use the Sum, which is less reliable than the
former. As last and least secure option, you can use None of the previous two.
3.4.1. CRC
It uses the 16-bit CRC known as X25 standard (generator polynomial: x16 + x12 + x5 + 1).
Below is a function written in language '
C'for the calculation of the CRC of a frame.
This function returns the calculated CRC value for a frame ‘data’ of length ‘len’.
short CalcularCRC(char * data, unsigned char len)
{
short icrc;
unsigned char i;
unsigned char j;
short temp;
icrc = 0x0000;
for (i = 0; i < len; i++)
{
if((icrc == 0x00) && (data[i] == 0))
{
icrc = 0x0000;
}
else
{
temp = ((short)data[i])<<8;
for(j=0; j<8; j++)
{

if(((temp ^icrc) & 0x8000))
{
icrc = ((icrc^0x0810)<<1) | 0x0001;
}
else
{
icrc <<= 1;
}
temp <<= 1;
}
}
}
return icrc;
}
As an example, if a frame formed by the bytes 10 02 07 00 01 in hexadecimal is to be sent, the
calculated CRC value will be 7C83 in hexadecimal and the complete frame will consist of values
10 02 07 00 01 7C 83.
From now on, unless otherwise specified, all values of a communication frame shall be
expressed in hexadecimal system.
3.4.2. Sum
In this case is the sum of all the bytes of the frame except for the two bytes for the error
checking field. For the same previous case of a frame formed by the bytes 10 02 07 00 01 the
calculated sum will be 001A and the complete frame will consist of values 10 02 07 00 01 00
1A.
3.4.3. None
In this case the two bytes for the error checking field will always be 03 03. For the same
previous case of a frame formed by the bytes 10 02 07 00 01 the complete frame will consist of
values 10 02 07 00 01 03 03.

4. ANSWERS, GENERIC FRAMES AND RETRANSMISSIONS
The usual way of carrying out the communication between a computer or PLC and the MC
2000T² control unit is where the computer or the PLC act as masters and the control unit makes
it as a slave. This means that the control unit will not send any communications by itself, will be
awaiting a command from the computer or the PLC and only then will respond to that command.
2
Some commands have an own answer and the MC 2000T control unit will respond that answer
when it receives this command. Other commands however, have no answer, which defines the
positive acknowledgement frame (ACK) for these cases. It also defines another generic plot,
which is valid for all command, and it is called negative acknowledgement frame(NACK). The
role of these generic frames is that the transmitter of a frame can know whether this frame has
been received correctly or not by the addressee.
4.1. ACK
Any plot that does not require a response by the recipient'
s own, and which has been received
correctly, must be answered with a positive acknowledgement frame (ACK). This applies both to
control units and to the computer or PLC. The only exceptions are the generic frames, since
neither the positive acknowledgement frame (ACK) or the negative acknowledgement frame
(NACK) must be answered.
The format of the positive acknowledgement frame is as it follows:
STX
DD
10
LT
07
UT
00
CMD
CRC
00
4.2. NACK
The negative acknowledgement frame is used to indicate that the control unit can not perfom
the action indicated by the received command. This occurs when, for example, the control unit
is on a marking process and a command that alters any of the parameters of the marking
process has been received. The control unit will not respond to this type of command until it has
finished the marking. Therefore, it must retry sending the command later.
The format of the negative acknowledgement frame is as it follows:
STX
10
DD
LT
07
UT

CMD
CRC
FF
4.3. Retransmissions
In some cases it is possible that some of the devices sends a frame and it is not answered by
the device such frame has been addressed to. This can happen, for example, if the
transmission line is electrically noisy and sent frame has been altered. The device to whom the
frame was intended could have lost the frame or discard it as being wrong after checking the
CRC.
In this case, if some time has elapsed since the transmission of the frame and the transmitter of
the same frame has not received a response or a positive or negative acknowledgement, it

must retransmit the same frame. The maximum waiting time for an answer to a sent frame is
500 ms.

It is not always necessary to include data for the counters, only if you are going to use a
Counter special mark within the text.
For those line parameters whose size is two bytes, the less significant byte must be sent first,
that is, if for example you want to set the character height of a line to 20.0 mm (200 tenths of a
mm), the value to send is 00C8 in hexadecimal and should be sent in the order C8 00.
For one byte size parameters, the value FF indicates using the same parameter value as the
previous line (the default value will be used if the parameter belongs to the first line).
For two bytes size parameters, the value FF FF indicates using the same parameter value as
the previous line (the default value will be used if the parameter belongs to the first line).
For the Font parameter, the value FF FF FF FF FF FF FF FF FF FF FF FF indicates using the
same Font as the previous line (the default value will be used if the parameter belongs to the
first line).

6. COMMUNICATION DURING THE MARKING PROCESS
As can be seen in the previous chapter, there are 6 commands that activate the marking
process: START, MARK TEXT, MARK FILE, START WITHOUT ANSWER, MARK TEXT
WITHOUT ANSWER and MARK FILE WITHOUT ANSWER. The first three indicate to the
control unit to send a reply to the sender of the command at the end of the marking process,
while the last three make the control unit skip this response.
If you are working in a networked configuration, with a PC and a number of control units
connected to a bus, it can be dangerous to use any of the first three commands because if the
PC sends, for example, the START command to 10 units control at the same time, as each one
completes its marking process it will sent it’s MARKING ANSWER to the PC. In addition to the
risk of collision between several responses from various control units, there is the problem that
the PC will not know what control unit corresponds each reply. These commands should be
used only when working with a single marker unit connected to the PC.
WITHOUT ANSWER commands are designed to solve such problems. The PC can send the
START command to 10 different control units and then sequentially ask for the state to each of
them through the STATUS command until the completion of all marking processes. Thus, it will
be able to determine unambiguously the result of each of the marking processes.
Anyway, if you set the control units connected to the bus so that they work with a network
topology (Parameter topology from Communications from Controller parameters), they will not
send the MARKING ANSWER even in the case of starting the marking process with START,
MARK TEXT or MARK FILE command.
Below is an example in which a PC governs simultaneously the marking process of two control
units (addressesc 1 and 2 respectively):

The STATUS questions and answers are repeated
until to the end of the marking process.
A minimum time of 200 ms between each repetition is
recommended.

Of course, this system can be used with more than two control units and also with only one. In
the latter case, if the control unit is configured to work on a point-to-point topology, WITHOUT
ANSWER commands should be used.

7. FRAGMENTATION OF A DATA BLOCK
As discussed above, in the case of wanting to make the transmission of a large data block it is
necessary to split that block on several smaller communication frames.
The maximum size of a frame is 250 bytes. These 250 bytes relate to the whole frame,
including the bytes of fields STX, DD, LT, UT, CMD, DATA and CRC. As bytes of fields STX,
DD, LT, UT, CMD and CRC add 7, the maximum size for data is 243 bytes. Therefore, any
block of data that exceeds this size must be fragmented. This only will happen when
transmitting files or text to be marked, and not in all cases.
Below is an example of fragmentation of a MARK FILE command when a file to be marked is
sent from a PC to the MC 2000T² control unit.

The total size of the transmitted file is 285 bytes. It has been divided into a first frame with a size
of 250 bytes (7 bytes for STX, DD, LT, UT, CMD, CRC and 243 bytes for file data) and a seconf
frame with a size of 49 bytes (7 bytes for STX, DD, LT, UT, CMD, CRC and 42 bytes for file
data).
As shown in the sequence of communication, the field UT (Last frame) of the first frame has a
value other than 00 (in this case FF), while the second frame has a value of 00, indicating that
this is the last frame of the entire block.
Moreover, it can be observed that once the first frame is received, the MC 2000T² control unit
sends an ACK indicating that the first frame has been received correctly and is ready to receive
the next frame of the block. The PC must wait for the ACK by the control unit before sending
the next frame. It should be borne in mind that the field UT of the ACK is always 00 since the
very ACK frame has not been divided into several smaller frames.

Significantly, the maximum frame size of 250 bytes is just that: the maximum size, which does
not imply that all frames least the last should have a size of 250 bytes. You can send smaller
frames if it is more convenient for you. The following sequence shows the same transmission
shown above, but this time sending frames of a maximum size of 100 bytes. In this case it has
been necessary to employ 4 frames instead of 2 frames.

Finally, it is not mandatory that all frames but the last one having the same size. It might be
possible for example, that the first had a size of 110 bytes, the second a size of 100 bytes, the
third a size of 90 bytes and the fourth a size of 13 bytes.
