Receiving a Message
Reception is possible whenever the terminal is on, indicated by
steady light in the ‘Standby’ keyboard indicator. The radio must be
set to telex mode and to the desired working channel.
When a call is detected the ‘Call’ keyboard indicator lamps turns on.
In case of paper-out during reception the connection is terminated.
Installation and Initial Set-up
Printer
The terminal uses an OKI Microline 280 parallel interface dot-matrix
printer with roll paper stand, please refer to the operation guide
delivered with the printer. The printer should be connected to the
printer socket at the rear of the control unit by means of the parallel
interface cable included with the printer. The printer is equipped with
a special firmware which allows the paper to be scrolled up so the
current line can be read in printing pauses, and scrolled back down
when printing continues. The firmware version can be checked by
performing a selftest: Disconnect the parallel interface cable. Press
the LF button (line-feed) while switching the printer on. When light
comes on in the indicator lamps, release the LF button. The printer
version is now printed followed by a test print-out. The version must
be: F/W 01.01 S33-67-7145.
Keyboard
The keyboard is a Cherry 1800 PC/AT compatible keyboard. The
self-adhesive keyboard template delivered with the equipment must
be mounted on the keyboard: Remove the protective paper. Care-
fully place the template around the function keys and indicator lamps
so the latter are fully visible.
Modem Set-up
Modem set-up mode is selected automatically when turning the
GMDSS telex on if no call codes are valid or if the abbreviated ID is
not valid. To change a valid set-up, a factory resetting of the modem
must be performed.
The 5-digit call code, the MMSI number and the abbreviated ID
allocated to the station may then be entered in turn. To leave a
setting unchanged just press ‘¬ Enter’. Otherwise key in a new
setting and press ‘¬ Enter’. The next item is then printed. After the
last item follows:
Accept settings (Y/N) ?
The process may be repeated if ‘N’ is pressed; the modem set-up
mode is left if ‘Y’ is pressed.
The answer back of the modem is generated by combining the 5-digit
call code or MMSI number, the abbreviated ID and an ”x” e.g.:
12345 abcd x
or
123456789 abcd x
