TT-3042B Remote Alarm
The TT-3042B Remote Alarm is connected to the TT-3020B by means of the Transceivers
X5 T-Bus connector. Please refer to section 2.5.3.
Figure 13: Remote Alarm with printer.
The TT-3042B Remote Alarm is intended for GMDSS installations.
The TT-3042B can all the same be used to print out SafetyNet EGC messages, via the
built-in thermal printer and indicate reception of EGC messages in general.
The TT-3020B Transceiver can accomodate up to 8 Remote Alarms at the same time, but
each alarm must have it's own unique T-Bus address in the range 0-7.
If more than one TT-3042B Remote Alarm is connected, the printer of the Remote Alarm
with the lowest address (first in the list of Remote Alarms seen with the
ru -l
command)
will be used as the default printer, whereas the other printers will be back-up printers
in case the first printer runs out of paper or has a malfunction.
If you do not connect a printer at the Transceiver, it will use the Remote Alarm printer
instead, but it is also possible to configure the Transceiver to use the Remote Alarm
printer always even if a Transceiver printer is available. Further you can select different
types of messages to go to either (or both) of the two printer types.
The Remote Alarm address is selected with a DIP Switch array inside Paper Bay of the
TT-3042B. Please refer to the
TT-3042B Remote Alarm Reference Manual
for detailed
information. The address selected for a Remote Alarm must not conflict with any other
Remote Alarm connected to the same TT-3020B Capsat Transceiver.
If you enter the Capsat Program's Terminal mode and type the command
ru -l
you will
see a list of the currently attached remote units and their addresses. In this way you will
be able to select unique addresses for all devices to be connected.
