The protocol of the printer was correctly set when the printer left EMIT. If the protocol has been changed, it
can be reset to the correct reading by following this procedure. If in doubt, you can at any moment turn the
printer off in an on to start over without storing modifications. The modification will only be stored when
pressing MODE and FEED at the same time (see step 17 below).
1. Turn the printer ON.
2. Press and hold the MODE button down until the red ERROR-LED has flashed 5 times, then release
MODE. The MODE-LED should now blink once (com.settings) and the ERROR-LED should also
blink once (RS232C Mode)
3. If the ERROR-LED didn't blink once, press MODE once (shortly), and count the number of times
the ERROR-LED blinks.
4. Repeat step 3 until the ERROR-LED blinks only once (it will cycle through 1, 2 and 3 blinks, 1
blink means RS 232-C protocol).
5. Press FEED button once, shortly (the MODE-LED will blink twice indicating that we are entering
baudrate-selection mode). Count the number of blinks on the ERROR-LED; it should be 4
(meaning 9600 baud).
6. If there were NOT 4 blinks, press MODE shortly and count number of ERROR-LED blinks
7. Repeat step 6 until ERROR-LED blinks 4 times.
8. Press FEED button once. (the MODE-LED should blink 3 times). Count the number of blinks on
the ERROR-LED; it should be 2.
9. If there were NOT 2 blinks, press MODE shortly and count number of ERROR-LED blinks.
10. Repeat step 9 until ERROR-LED blinks 2 times.
11. Press FEED button once (the MODE-LED should blink 4 times). Count the number of blinks on
the ERROR-LED; it should be 1.
12. If there was not 1 blink, press MODE shortly and count number of ERROR-LED blinks.
13. Repeat step 12 until ERROR-LED blinks 1 time.
14. Press FEED button once (the MODE-LED should blink 5 times). Count the number of blinks on
the ERROR-LED; it should be 3.
15. If there were not 3 blinks, press MODE shortly and count number of ERROR-LED blinks.
16. Repeat step 15 until ERROR-LED blinks 3 times.
17. Press MODE and FEED simultaneously to store new settings.
USING MTR4 WITH A PC
USB connection
Connect the MTR4 to a PC by using the supplied USB cable. Connect the cable to input 'D' on the MTR4
and the other end of the cable to a vacant USB port on the PC. Turn on the MTR4. Install the USB-driver
by inserting the CD containing the USB-driver into the PC's CD-ROM player, and pointing to this drive (for
example D:) when the PC asks for driver files. Please note that this installation consists of two steps: first a
"USB Serial converter" must be installed; second a "USB Serial Port" can be installed. The USB serial port
normally gets the next free com-port (com3, com4, etc.), depending on how many com-ports that is present
in the PC.
Storing in memory
The MTR4 stores up to 2040 e-cards, with up to 50 controls each, in its memory. If more than 2040 are
read and the memory runs out, the first e-cards read are erased.
When started by pressing 'Clear/ON', the MTR4 makes a pointer to a new event.
Batteries
The MTR4 uses a built in 3,6 V Lithium battery. This battery has sufficient power to provide approximately
10 years of "average" use. The most power-consuming operation is spooling the MTR's memory. The
lifetime calculations have been done by assuming that every card that is read by the MTR4 is sent 3 times to
a PC/printer (once when reading, and then 2 later spooling operations). If spooling is done much more
frequent or software is "abusing" the MTR by requesting information repeatedly (polling), the lifetime of
the MTR will be shortened. If the battery voltage drops below 3.59 V, the battery should be replaced
