Navico 2kW, Installation Manual

Page: 36 / 80

34 | Connect Simrad GB40 or Northstar 8000i
The compass must be NMEA compliant and configured as follows:
•
10 Hz update rate
•
4800 baud
The compass must be able to supply the NMEA 0183 HDT, HDM, and HDG heading sentences
(all other sentence types will be ignored).
The NMEA compass must be directly connected to the 8000i / GB40 through the Utility port and
the radar processor through the NMEA/COMMS port.
Compass data is appended to the radar data by the radar processor and then broadcast over
the network to the 8000i or GB40 displays and other devices. This enables more precise radar
chart overlay and target tracking (MARPA).
The NMEA compass cable is not supplied but the pinout of the NMEA/COMMS port is shown for
information:
Pin Function
3 NMEA TX+ data
4 NMEA Ground
5 NMEA Rx-data
6 NMEA RX+ data
9 Shield
11 12 V Compass power (100 mA max)
It is recommended that a single compass data source is used for a 8000i network.

terminals.
4 kW system is 12 or 24 V DC
D 24006694 AT10HD SimNet to NMEA 0183 converter converts SimNet heading to 0183
@ 10 Hz to allow for accurate MARPA and overlay.
Has two SimNet ports to sit on SimNet Bus and a 2 m (6 ft) cable
terminating with 12 pin female connector. This plugs into socket labeled
NMEA / COMMS on the radar processor box.
D1 AA010070 Utility cable 2 m (6 ft) with 12 pin female connector on one end and 12 bare
wires on the other. This plugs into socket labeled Utility on the 8000i or
GB40 Master NavComputer. This cable is shipped with each NavComputer.
D2 AA010070 Same cable as D1 but uses different colours. Cable needs to be ordered
separately. Connects to the radar processor labeled NMEA /COMMS.
E Ethernet cables: All ethernet cables need to be ordered. They are not
supplied with any product. They are available in four lengths as well as self
terminating bulk rolls
