Compass selection and interface setup
As several compasses may be connected to GI51 at the same
time, one of these has to be defined as source for the heading
output on the Robnet, NMEA, step, radar and sin/cos port.
When GI51 is connected to a Simrad autopilot via Robnet,
compass signal type has to be set at installation in the autopilot
interface menu. Steering and monitor compass is then selected in
the user setup menu (refer autopilot manual).
As stand alone unit, the compass in use is automatically selected
at power-on in the following order:
Synchro (1
st
priority)
→
Step

RGC
