These two terminals connect to the NMEA 0180,
0182, or 0183 output of a Loran C Receiver, GPS

These terminals are used for transmitting data out
of the autopilot to either, a ComNav Remote
Heading Display, a satnav, or other type of
navigation computer.
The function of these terminals is determined by
dip switch settings inside the autopilot (see Table
III) between ComNav's Remote Heading Display
format, the N+1 Heading format (used with the
Magnavox MX4102 or MX5102 SatNav
equipped with the MX41D N+1 interface circuit
board, for example), or the BCD Heading format
(used with the Furuno FSN 50 SatNav equipped
with the DE-FSN8-8M-1 interface circuit board,
for example).These terminals can also be
configured as an NMEA 0183 data output port by
special factory order. The +5V terminal is
included as a convenience for wiring a Remote
Heading Display.
26. ALARM OUT
27. WATCH ALARM
28. +PWR
29. - PWR
The Alarm Out terminal is used to run external
alarms. +PWR volts will appear on this line in the
event of a fatal alarm (ie. an off course alarm,
output failure alarm, etc.), or if the man on watch
fails to respond to the autopilot Watch Alarm.
The Watch Alarm terminal is an input to the
autopilot used to turn the optional Watch Alarm
on and off. The +PWR Volt and Common
terminals are provided as a convenience for
wiring up either the Watch Alarm controller or an
External Alarm.
