RFC35 Electronic Fluxgate Compass
(optional)
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.
RFC35 can operate as a low cost back-up compass for the AP26
and AP27 autopilots.
NMEA compass (optional)
A well performing compass that outputs NMEA 0183 HDT or
HDG messages at 10 Hz
can be connected directly to the AC20
or AC40 autopilot computer.
The AC10 Autopilot Computer has no port for NMEA compass
input.
It is absolutely necessary for the autopilot that the heading rate is
minimum 10 Hz.
Simrad gyrocompasses
Depending on the model there is direct NMEA0183 interface or
you will need an optional GI51 interface unit to get NMEA0183
interface. Ask your Simrad dealer for information.
1.9 Optional equipment
A series of optional equipment are available for the basic AP26
and AP27 systems.
R3000X Remote Control
A small handheld remote control with two push buttons for
power steering or course selection (port and starboard), and one
push button with built-in lighted indicator for limited mode
change.
