Description 1 1 Description Description This manual provides information for configuring, installing and operating the TT-3042D Remote Alarm. For general information regarding the Arcnet standard please refer to ATA Standards Committee’s ‘ANSI/ATA 878.1 Local Area Network: Token Bus (2.5 MBPS)’.
Description Description Specifications Specifications Specifications Specifications Indication Visual: LED indicators with dim function. Text back-light with dim function. Call reset OK button Distress transm. Patch covered button with 5 sec activation delay. Arcnet/serial port DB 15M conn: Arcnet: Twisted pair/bus topology, max 100 meter cable.
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.

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. Page 4 4 Page...
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.

Installation Installation Installation Installation 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.

Connectors Operation Operation 2 2 Operation Operation 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.
Operation Operation Connectors Connectors 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.
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.
6. Insert the paper roll in holder and close the roll holder. 2.1.10 Paper Saving For paper saving the TT-3042D cuts away succeeding blank lines. A maximum of two blank lines are allowed after each other. In 40 chars per line mode succeeding spaces are also cut away.
15V) 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.
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.
4800 baud, the same as for NMEA data input. The port parameters are fixed. 2.1.16 Remote Turn-On In power saving applications the TT-3042D can be turned on remotely. Jumper W3 must then be set in position 1-2 or the Remote Alarm will be turned on permanent.

Fault Diagnostics Fault Diagnostics Fault Diagnostics Fault Diagnostics 3 3 Fault Diagnostics Fault Diagnostics If power diode does not turn on check fuse, voltage source and remote turn-on setting. If power diode is blinking then Arcnet connection to transceiver is failing. First check if transceiver is turned on, then check the Arcnet cabling, if no result then check Arcnet address settings for all units coupled to transceiver.
