RFC35 Electronic Fluxgate Compass
A compact heading sensor from Simrad with 15 m (45 feet) of
cable. The direction of the earth's magnetic field is sensed by a
floating ring core in a fluxgate coil and transformed to a digital
signal read by the autopilot steering computer.
RFC35R Rate compass
Fluxgate compass with integrated rate sensor. Provides a dramatic
improvement to the dynamic performance of both the autopilot
and a stabilized radar display.
Same dimensions as RFC35.
CDI35 Course Detector Interface and
CD100A Course Detector
Interface and sensor unit to connect AP20 to a magnetic
compass. The AP20 provides excitation current for CD100A and
converts the analogue sin/cos signal to digital two wire format
for the autopilot steering computer.
Note ! You can not connect both an RFC35 and a CDI35 at the same
time.
NMEA compass
(Applies for AP20 V1R3/J300X V1R8)
Any NMEA 0183 compass with HDT, HDG or HDM messages
can be connected directly to the J300X/J300-40X junction units.
Other fluxgate compass models
The optional CI300X can interface AP20 to fluxgate compasses
with heading signal on a sine/cosine format.
Simrad RGC10 and RGC50 gyrocompasses
The optional CI300X unit is needed to interface the two
gyrocompass models. No other gyrocompass models can be
interfaced to AP20.
