15. RUDDER POSITION
16. RUDDER COMMON
These three terminals connect to the
rudder follower. With the cable from the
distribution box unplugged from the rear
of the autopilot, and the rudder turned to
dead ahead, the resistance between
RUDDER POWER and
RUDDER POSITION, and RUDDER
POSITION and RUDDER COMMON
should be equal, and each measure
approximately 600 ohms if you are using
a ComNav Rudder Feedback.
17. NAV SIGNAL
18. NAV RETURN
These two terminals connect to the
NMEA 0183 output of a Loran C
Receiver, GPS Receiver, or other type of
navigation device so equipped.
Whenever the autopilot is turned on, the
LED next to these terminals will light
while data is being received.
19. RAI SIGNAL
20. RAI RETURN
These two terminals are used to run up
to three ComNav Marine rudder angle
indicators. Multiple rudder angle indicator
installations must be wired in series. If all
the indicators move to port when the
rudder is moving to starboard, reverse
the connections to these terminals. If
only one of the indicators moves to port
when the rudder is moving to starboard,
reverse the connections at that indicator
only. Use the ZERO ADJUST
potentiometer on the Distribution Box
circuit board to make the indicators read
zero degrees when the rudder is dead
ahead.
