30 | Connect Simrad GB40 or Northstar 8000i
Both the Simrad GB40 and the Northstar 8000i systems interface to the Navico radar via an
ethernet network. Although the two types of display system have the same type of ethernet
network connectivity, they differ in the way they accept heading information for MARPA and
accurate chart overlay.
The Northstar 8000i requires NMEA 0183 heading information to be sent to both the Master
NavComputer and the radar processor module. The Simrad GB40 NavComputer gets heading
information over SimNet. The radar processor module requires the use of an AT10HD SimNet to
NMEA 0183 converter to feed SimNet heading information at 10 Hz for optimum MARPA
function.
Note. Do not use a standard AT10 converter, as this only passes heading information at 4 Hz.

Ethernet cables: (Simrad GB40 and Northstar 8000i)
The connection between the radar processor and the GB40/8000i system is via an ethernet network. One
ethernet cable is used to connect the radar to a Navico 8 port network linke. Select the desired length.
If there is only one NavComputer with radar, a crossover cable can be used.
