Comnav Sin/Cosine Interface Box

Brand: Comnav
Part Number: 21010004
The ComNav Sine-Cosine Interface Box allows an NMEA 0183 compass to be used with an autopilot that can only accept a traditional analog-signal type of compass input (usually referred to as “Sine-Cosine” signals). It can also be used to interface other NMEA “heading” devices to analog-compass-input autopilots & other navigation equipment.

The Interface Box requires a special ComNav cable when it is used with ComNav 1000/2000 Series Autopilots; this cable PN 31110023 is sold separately.
