Navico 2kW Installation Manual page 36

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:
It is recommended that a single compass data source is used for a 8000i network.

2 kW scanner comes with a 15 m (49 ft) cable attached. (B)
4 kW scanner comes with a 15 m (49ft) cable that will need to be connected
to the scanner. Cable from Scanner connects to Radar Processor box. An
optional longer cable is available but only up to 20 m (65.5 ft).
Optional 20 m (65.5 ft) scanner cable. Will require disassembly of dome to
connect this replacement cable. Cable has radar processor connector on one
end, and three small terminated flat connectors on the other.
CAUTION: This cable should only be installed by an experienced radar
service technician!
Radar processor module. No cables supplied. Connects to GB40 system via
Ethernet.
The radar box requires heading @ 10 Hz. For vessels using NMEA 0183,
order cable AA010070 to connect to a suitable heading sensor.
2 kW system is 12 V DC ONLY 25 W max. Power connects to the two screw
terminals.
4 kW system is 12 or 24 V DC
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.
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.
Same cable as D1 but uses different colours. Cable needs to be ordered
separately. Connects to the radar processor labeled NMEA /COMMS.
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
