Signal Processor Unit
PN 2014000

The Signal Processor Unit (SPU) accepts a number of inputs from the other components of
the autopilot system, and then processes them as necessary to control the movement of the
vessel’s rudder to maintain a given heading. As well as steering the vessel, the sophisticated
software within the SPU continually checks all aspects of the autopilot’s performance, and will
advise the user via the Control Head if any problems are encountered.
The most essential data for the SPU is the heading information and the rudder feedback
signal.
The SPU can accept heading information from an NMEA 2000 device; it can also accept
heading information from an analog compass port, or one of its 2 NMEA 0183 ports.
The SPU requires the rudder feedback signal sent to its analog port at J4.
There are other wiring ports that are provided for the backward compactivity to

autopilots. See appendices under Legacy products for more details.
