The TT-3042D Remote Alarm for the Capsat TT-3020C and TT­3022D 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.

Page Page 44 7Jul987Jul98

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.

7Jul987Jul98 Page Page 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

The TT-3042D Remote Alarm for the Capsat series of Inmarsat-C
transceivers operates as a message and status printer, it also
displays the general system status.

2.1.1 Distress Transmission

Distress transmission is activated by lifting the protective cover
and pressing the Distress button for 5 seconds.

When the Distress button is pressed the light in button turns on.
When the Distress button has been pressed for 5 seconds, the
sounder starts to beep to indicate that the distress request has
been send to the Capsat transceiver. The Distress button can
now be released and the sounder stops. The Distress button light
starts flashing and continues to do so until a successful distress
call has occurred. After that, the Distress button light turns on.

If the Distress button light does not turn on and the sounder starts
to beep when Distress button is pressed, the Remote Alarm is
unable to issue the distress request. If the Power diode is
flashing there are no Arcnet connection to Capsat transceiver.

2.1.2 Status Indicators

Power: The power diode is used as a power-on indicator,
furthermore this diode indicates communication status with the
transceiver. When the transceiver is turned off or the Arcnet
connection is disconnected, the power diode is flashing to
indicate the fault situation.

Login: The Login diode is used to show the login status for the
transceiver. When turned on the transceiver is logged in.

Paper: The Paper diode is used to show the paper status for the
printer. When turned on paper low is detected and printing is
disabled. When paper is loaded and paper is detected the
paper diode is flashing in 20 seconds or until OK is pressed
before printing is resumed. Feeding distance is increased when
paper empty is detected.

2.1.3 EGC Indicators

When receiving an EGC message, the corresponding diode
turns on and the sounder gives notice. When message is
acknowledged and the OK button is pressed, the diode turns off
at all Remote Alarms.

Distress/Urgent: The Distress/Urgent diode is used as an
indicator for the two highest levels of EGC, these are distress
and urgent calls. The sounder turns on until the OK button is
pressed.

Safety: The Safety diode is used as an indicator for EGC safety
information. Safety EGCs are usually SafetyNet navigational and
weather information.

Routine:The Routine diode is used as an indicator for EGC
routine information. Routine EGCs are usually status and service
messages for the Inmarsat-C earth stations.

2.1.4 Mail Indicator

The Mail diode indicates that mail has been received by the
transceiver. The Mail diode turns off when the OK button is
pressed.

2.1.5 Call Group Reset

The OK button is used as a single reset button for all call groups.
If an EGC/Mail indicator is turned on, pressing OK button causes
an receipt to be send back to the transceiver.

2.1.6 Audio Indicator

The audio indicator gives a notice to attract attention when
Remote Alarm status is changed.

The sounder also gives a notice when communication status to
Capsat transceiver is changed, printer error or printer paper
empty is detected. It also turns on when an alarm request has
been send to the transceiver.

The sounder timeout option, set by the DIP switch, must not be
enabled when the TT-3042D is used as a remote alarm. The
sounder timeout option must only be enabled when the remote
alarm is used for printing only. When the timeout option is set
the sounder will not be turned on for more than 10 seconds.

2.1.7 Dimmer Control

Diode light level and text background light level is controlled
by pressing the OK button and then pressing the FEED button a
number of times.

2.1.11 Dot Energy

The printing energy used to write each dot determines how
black the printout is.

The dot energy is selected by DIP switch setting. When the dot
energy is set to normal, printing head energy is lower and
printer lifetime is prolonged.

2.1.12 Selftest Printout

Selftest printout is initiated when OK and FEED is pressed at
powerup. The selftest printout prints character set and DIP
switch setting. Normal Remote Alarm operation is resumed after
printout. If OK is pressed for 15 seconds the Remote Alarm is
softreset and selftest printout is initiated.

2.1.13 NMEA 0183 Sentence Input

When configured for NMEA 0183 input/output the NMEA 0183
input can be connected to a navigator with a NMEA 0183 output.
The input is optical isolated and only two wires are to be
connected. Both inverted TTL (+5V/0V) and bipolar (-15-0V/1V­15V) signal levels are accepted. The NMEA 0183 input is optical
isolated when jumper W2 is in position 1-2 (low).

The TT-3042D automatic detects if a NMEA 0183 navigator output
has been connected. Standard NMEA 0183 messages are read,
position and velocity data extracted and transferred to the
transceiver.

NMEA 0183 sentences read are: GGA, GLL, VTG, GXP, GDP,
GOP, GLP, TGA, HDT and HSC. Please refer to navigator manual
for further information.

22 OperationOperation

The NMEA 0183 communication parameters are: 4800 baud, 1
stopbit and no parity.

Hint:To test the NMEA 0183 link the TT-3042D can be configured
to serial data input on NMEA 0183 port, see section 1.5.2, NMEA
0183 sentences should then be printed out.

2.1.14 NMEA 0183 Sentence Output

If the NMEA port is configured for NMEA 0183 input/output and
NMEA 0183 data is received the position and velocity
parameters are extracted and transmitted to the transceiver.

If on the other hand no data is received on the NMEA 0183 line
for a certain time the TT-3042D requests position and velocity
data from the transceiver. If the transceiver is equipped with an
internal GPS board and has updated position and velocity data
these data is transferred to the TT-3042D. The TT-3042D then
transmits position and velocity formatted as standard NMEA 0183
sentences on the NMEA 0183 port Tx line.

NMEA 0183 sentences output are: GLL, VTG and ZDA.
When using the NMEA 0183 output jumper W9 should be placed

in position 1-2 (low) to obtained a balanced signal.

2.1.15 Serial Print input

When configured for serial characters input on NMEA 0183 port,
jumper W2 and W9 must be in position 2-3 to obtain single­ended RS-232 voltage signals.

The protocol is two wire Ready/Busy control. X2 pin 10 will go to
a positive voltage level when buffer is full to indicate Busy.
When printer is ready to accept data a negative voltage is output
on X2 pin 10.
