4.10 NMEA 0183 connections

The GPM400 processor has 2 NMEA 0183 connectors.
Dual speed: 38.4 or 4.8 Kbps as required.
These may be used for connection of NMEA compliant devices for
data such as:
• Fastheading, from an autopilot or fastheading sensor.
This is required for Radar target acquisition (MARPA). See
page 52 and your separate autopilot instructions.
• AIS information (for radar target identification).
See page 53 and your separate AIS receiver instructions.
• Other NMEA data (such as 3rd party GPS or autopilot sys-
tems).
For other NMEA device connections refer to the separate man-
ufacturers instructions.
Multiple NMEA devices
You may connect NMEA devices to any GPM400 including the
master GPM. You should only connect 1 device of any particular
type to the G-Series system (including any connected databus or
networked electronics).
Notes
Supplied with GPM400
processor.
For example: Your system should have GPS connected to one
place only. Duplicated GPS data will produce erratic behavior
within the system.
