The TT-3042D Remote Alarm for the Capsat TT-3020C and TT-
3022D series of Inmarsat-C transceivers fulfil all GMDSS
requirements for remote indication and printout of EGC
SafetyNet messages, initiation of distress transmissions, and
general system status display.
The TT-3042D is connected to the transceiver through a single
shielded twisted pair cable that may be extended up to 100
meters.
The TT-3042D displays four types of EGC message priorities, a
receive mail indication and a login status.
A build-in printer enables hard copy printing of received EGC
messages at the Remote Alarm location.
The TT-3042D includes a distress button, allowing direct
transmission of distress calls from the unit.
A navigator with NMEA 0183 output can be connected directly to
the TT-3042D for routing of position data back to the Capsat
transceiver for automatic update of e.g. safety and distress
information.
The NMEA 0183 input port can be configured for serial input
port for text to be printed, the protocol will then be two wire
Ready/Busy.
The NMEA 0183 input connector includes 3 additional EGC
group outputs. These outputs allows additional alarm indicators
to be connected in accordance with Your specific requirements.
The TT-3042D is powered through its own 10.5-32 Vdc floating
supply, conforming with the GMDSS requirements.

Up to 7 Remote Alarm units with different Arcnet address setting
can be placed on various locations onboard ship, all connected
to one Capsat transceiver with the Arcnet.
EGC SafetyNet messages are routed to all Remote Alarm printers
connected. If no Remote Alarm is equipped with a printer or
Remote Alarm printer fail, the EGC Safetynet message is routed
to transceiver printer, computer printer or stored in disk.
The build-in printer can be configured for 40 or 80 chars/line,
automatic word wrapping is performed on long lines.
When printing at 40 chars/line the TT-3042D perform
papersaving compression on incoming data by stripping
leading spaces and by allowing a maximum of two succeeding
blank lines.
The build-in printer can be configured for bottom-to-top printing
and automatic page breaking to allow printouts to be read
directly from paperstrip at printout.
The build-in printer is maintenance free, printing on 112 mm
(4.4") width thermal paper rolls of length 24 meters. A build-in
paper detector indicates when paper is low. The printer is
temperature compensated to give equal printing quality over a
wide temperature range. Paper loading is eased by extended
feed length on paper empty condition.
Indicator and text background light level is selected by front
panel operation.
The TT-3042D is equipped with remote turn-on for power saving
configurations. Remote turn-on is enabled by jumper setting.

1.31.3 ConfigurationConfiguration
Before installation of the TT-3042D, configuration of Arcnet
address should take place.
It is important to observe that all devices connected to the same
transceiver must have different address settings. If this is
ignored, the Arcnet will not operate properly.
The TT-3042D Remote Alarm is configured by setting an 8
position DIP switch located under the paper inlet. To set
operating parameters remove paper and turn off power.
Note: Operating parameters are only read at power-up or
softreset so changes in operating parameters will not change
operation until a power-cycling or softreset is performed.

1.41.4 InstallationInstallation
To following brief outline may be used to get the TT-3042D up
and running as a printer together with a Thrane & Thrane
transceiver which supports Arcnet - hardware as well as software
wise.
1. Set an unique Arcnet address as described in section 1.5.2.
2. Connect the 3042D to the transceiver by means of the
accompanying interconnection cable (15 pole SubD
connectors).
3. Connect the 3042D to a DC power source by means of the
accompanying power cable. For security reasons take care
to connect the ground/chassis wire properly to ground.
When power is applied it should now be possible for the
transceiver to print on the TT-3042D when needed or initiated
by the user.
In case the accompanying Arcnet interconnection cable is not
suitable and another cabling has to be made please observe the
guidelines given below regarding establishment of an Arcnet.
Please note that the Arcnet system supported is a twisted pair in
bus topology.
•The Arcnet bus should be wired as a bus meaning that there
must be no branches or stubs. The Arcnet devices attached
should be placed like pearls on a string.
•The Arcnet bus will have two ends and both of these should
be terminated with a 100 Ohm resistor (±1%). The TT-3042D
does NOT contain any termination-resistor. If needed the
termination resistor could be placed in the 15 pole SubD
connector connected to the twisted pair cable. This is the
case for the accompanying cable.

DescriptionDescription
7Jul987Jul98 PagePage 99
•Always use shielded twisted pair cables and shielded
connectors (otherwise the EMC specifications are not
guarantied to be fulfilled).
•The length of the cable making up the Arcnet bus should be
no longer than 100 meters.
•Minimum spacing between devices connected to the Arcnet
bus is 2 meter of cable.
•No more than 8 Arcnet devices (including transceiver) must
be connected to the Arcnet bus.
In case the NMEA input/output or serial input and/or the 3 status
outputs have to be utilised please refer to section 1.5.2, 2.1.0 and
2.1.11 with respect to pin assignment, jumper setting and
functionality.
