Furuno Output
The Furuno output is a proprietary message format typically
used with Furuno and other brands of radars and autopilots. Two
user-configurable options are available: true or magnetic heading
and 25 millisecond (40 Hz) or 200 millisecond (5 Hz) data rate.
The default rate is 200 millisecond/5 Hz.
Optional Stepper Components
An optional interface unit is available to generate a stepper
output. The stepper interface uses an NMEA HDM or HDT serial
message input to generate the stepper signal format.
The stepper signal replaces traditional gyro outputs used with
satellite communication systems, autopilots, and steering
displays. The Stepper Interface unit is shown in Figure F-1 while
the specifications are presented in Table F-6.
Please refer to the Stepper Interface User Manual for specific
wiring instructions.
