Note: When connecting the output to a relay or other inductive
device you should fit a spike suppression diode e.g. 1N4001.
SeaTalk and alarm cable
Cable for connecting SeaTalk devices and an alarm to the G-Series
system.
Cable Part number Notes
1.5 m (4.9 ft) SeaTalk /
Alarm Out cable E55054 Supplied with the GPM
processor unit.
3.9 NMEA 0183 connection
The GPM processor unit has 2 NMEA 0183 connectors.
The NMEA 0183 ports are used for connecting NMEA 0183
compatible equipment to the G-Series system, for the purposes of
sharing the following types of data:
• Fastheading — from an autopilot or fastheading sensor. This is
required for radar target acquisition (MARPA).
• AIS information — from an AIS receiver or transceiver. This is
for radar target identification.
• Other NMEA data — for example from third-party GPS receivers
or autopilot systems.
Both connectors support 38.4 or 4.8 Kbps baud rates.
The following diagram illustrates the connections between the GPM
processor unit and an NMEA 0183 device. The connection is made
using the NMEA 0183 cable, supplied with the GPM processor unit.
The pin number for each connection is listed below the diagram.
The input and output connections on the GPM processor unit and
the NMEA device are crossed. For example, the positive OUTput
of the GPM processor unit is connected to the positive INput on
the NMEA device.
