1 GENERALITY

1.1 FUNCTIONING

Most of the printers available on the market allow printing data, text or graphic
supplied by a computer or a PLC. When designing the MRSi and MRTi
printers, we took into account many special requests from our customers in
order to design the most universal O.E.M printer available today.

Several housings are available in order to integrate these printers on
machine front panel or a 3U equipment

With its dotmatrix technology, this printer is the right solution for tracability
applications, when a long preservation of the ticket is required.

Many features are included in the printer software allowing graphic printing
and a lot of special effects:

Bonus:

● Compatibility: with printer language like Epson ESC/P 9 pins,

HP PCL Raw or Megatron MRS

● 2 character fonts in 6x10 and 10x10 matrix

● Selftest and Hexadecimal dump to debugging the interface

● Windows 2K / XP and Vista 32 driver available on our website

www.megatron.fr.

a permanent concern of improvement, the contents of this

manual are subject to change without notice.

1.2 MATERIAL DESCRIPTION

The printer is designed around a PSD3434E microprocessor, with 7K-Bytes of
RAM available for buffering datas. An internal watchdog in the microprocessor is
activated to insure an operation in strongly polluted industrial environment.

Printing heads: 2 kinds of head can be used :

- MRSi printers are equipped with Epson M-160 dot-matrix head family with 4
needles allowing slow graphic printings with long delay between lines

- MRTi printers are equipped with Epson M-190 dot-matrix head family with 8
needles allowing fast text or graphic printings

Serial Interface: The printer can be connected in serial in TTL or RS232C levels.
Hardware (RTS/CTS) and software (XON/XOFF) handshakes are simultaneously
supported.

USB 2.0: The printer can be connected in USB 2.0 at full speed. Printer class
(class 7) is supported.

Accessories: Several accessories like Line-Feed button, control LED, paper-end
detector and rewinder are directly managed by MRSi and MRTi printers.

Power Supply: Depending of the model, VCC power supply must be supply in
DC 5 V, DC 9 to 40 V or Mains.

2 PRINTER OPERATION

2.1 START-UP

1. Connect the power supply and connection cables

2. Turn power on

The interface will control its memory, set its parameters according to the data
menu stored in its Flash memory, look for the possible presence of a clock
circuit and moves the printing head for one line to determine the dot number
of the connected head. At the end of this initialization cycle, the printer is
ready for receiving characters.

2.2 SYSTEM REINITIALIZATION (RESET)

The printer is designed with a watchdog which makes a reset at power-up
authorizing the use of a slow ascent supply. About 300 milli-seconds after the
controller is powered-up, this one is ready for operation, having ended its
reset cycle.

2.3 SELF-TEST OR HEXA DUMP

If, after a reset or at power-up, the linefeed
button is maintained pushed, a self-test
cycle is run. The printer prints its name.
At this time if you :

● continue pressing the LF button,

the hexadecimal dump mode is
invoked. A message 'DUMP HEXA
MODE' is printed. Release the LF
button. Now the value of all the
received data will be printed in
Hexadecimal followed by their
ASCII value if printable. Power-off
the printer to leave this mode.

● release the LF button, all the

parameter settings and the
character set are printed. At the end
of the self-test the printer will work

normally.
The self-test gives only a probability of correct operation of the printer; indeed,
the self-test procedure does not use transmission, this one can only be tested
in real mode.

2.4 3U RACK WITH PAPER REWINDER (MRXI-X2XX)

This case is a small mono-block case
integrating a printing head, a paper roll
support and a paper rewinder.

This case is compatible with the EURODIN
standard and can be directly installed in a
3U system rack.

The interface is fixed at the back of the
case making an autonomous and
compact product. The front door can be
opened to give access to the paper roll.
The ink cartridge can be changed by
removing the first part of the door.

The dimensions of this printer are identical to those of the previous printer.

The same printer exists without a paper rewinder. For more information about
this product, refer to MRSi-x1xx and MRTi-x1xx documentation.

MRSi & MRTi – x2xx v0.3 8

2.4.1 Paper End

If a paper-end occurs, the red LED will blink

and the printout is hanging.
Depending of the « No Paper » menu setting,
the paper defect can :

● be totally ignored (ignored)

● stop the printout but can accept the

data until the buffer is full (Fill Buff.)

● stop the printout and stop the data

transmission (Set Busy)

2.4.2 Status Led

A status LED informs the user of the possible defects of operation.
When this led is out, it indicates a correct operation, a blinking LED indicates
an abnormal status which is explained in the table below:

5 CONFIGURATION MENU

Two different ways are available to configure the printer:

• by the interface (see command esc ])

• by a printed configuration menu.

Here is described the printed configuration menu.

All the navigation in the Menu is made thanks to the LF push button.
Long push on the button is written <<LF>> and short push is written >LF<.
To indicate several short pushes, >LF< is followed by the quantity: >LF x2<

Activation: To activate the Configuration Menu, shortly press 4 times the
Paper Feed button ( >LF x2< ). A 'MENU ACTIVATED' message is then
printed and the first group of configuration items are printed too..

Navigation: In order to modify the settings the following steps have to be
followed:

• navigate through the groups (1)

• navigate through the different items of the group (2)

• modify the value of the items (3)

Timeout: To avoid lock of the printer in the configuration Menu, if no actions
are made on the LF push-button during 15 seconds, the Menu is aborted.
All changes are lost and a 'MENU TIMEOUT' message is then printed.
The printer can accept new data from the interface...

MRSi & MRTi – x2xx v0.3 18

(1) Navigate through the groups:

<<LF>> A long push on the LF button enters in the different items of

the selected group (2).
First Item is then printed...

>LF x1< One short push on the LF button displays the next group.

New group is then printed...

>LF x2< Two short pushes on the LF button display the previous

group. New group is then printed...

>LF x3< Three short pushes on the LF button save the modifications

and exit the configuration mode.
The message ‘MENU EXITED’ is printed out and a reset of
the printer is then performed.

(2) Navigate through the items of a group:

<<LF>> A long push on the LF button enters in the different values

of the selected item (3).

>LF x1< One short push on the LF button displays the next item.

New item and its associated value is then printed...

>LF x2< Two short pushes on the LF button display the previous

item. New item and its associated value is then printed...

>LF x3< Three short pushes on the LF button exit the navigation in

the items and come back in the group navigation level (1).

(3) Modify the value of an item:

<<LF>> A long push on the LF button validates the new selected

parameter and prints this value in double width for control
purpose. If the value is a clock item, the clock chip is
immediately updated. For other items, the configuration menu

has to be exited before the values are effective.

>LF x1< One short push on the LF button displays the next value.

See note on the >LF x2<

>LF x2< Two short pushes on the LF button display the previous

value. Note: The new selected value is only printed after a
certain inactive time thus allowing multiple short presses
without printing. This works only for multiple pushes higher
than three, because >LF x2< and >LF x3< are used for
navigation purpose.

>LF x3< Three short pushes on the LF button exit the navigation in

the values and come back in the item navigation level (2).

6.3 CONTROL CODES ESC/P 9 PINS

The compatibility ESC/P 9 PINS has been implemented in order to allow the
printer to works with computers. Only the graphic functions are implemented.
The other control codes are ignored. The codes implemented are shown with
a mark in the column ‘9 Pin’ of the table.

6.4 CONTROL CODE ESC/P BASIC

These codes are less compatible with ESC/P, but they give some functions
more specific to the printer. Most of these codes work same way as 9 pins.

Attention, Major difference in graphic:
The graphic modes are very similar, but the function of the CR at the end of
the graphic is different :

• for ESC/P Basic, the code CR makes a line feed like a LF code.

• for ESC/P 9 pins, the code CR makes only a carriage return without any

line feed.
The characters with their ASCII values between 01 hex and 1F hex are
control characters and are not printable. These characters allow to modify the
behaviour of the interface (control characters). .
