In addition to TracVision and GPS connections,
the ADCU rear panel includes three optional
compass outputs of the following formats:
• One sine/cosine output
• Two serial outputs (each configurable for
NMEA 0183, KVH RS-422, or Cetrek)
These compass outputs allow you to supply the
GyroTrac sensor’s heading data to other
electronic devices, such as autopilots, radars,
remote displays, plotters, and computers
onboard the vessel.
NOTE: KVH offers a rotating card display (KVH part
#19-0120) for presenting sensor heading information
(see Figure 54). This device, powered by 11-40 VDC,
connects to any one of the ADCU’s serial outputs,
configured for NMEA.
NOTE: If you wish to connect a ship’s gyro to the
system, connect the gyro to the ADCU’s GPS input
terminals (see Figure 26 on page 15).
Before you connect an external device, consider
the following guidelines:
• The device must comply with NMEA
Standard 2.2
• Data conductor wires should be
minimum 18 AWG (0.75 mm
2
), twisted-
pair, stranded, tinned marine cable
• Do not use cables with wire diameters
larger than 12 AWG (4 mm
2
), since this is
the largest gauge the ADCU can accept
• Always follow the manufacturer’s wiring
guidelines in the device’s manual
This appendix explains how to wire and
configure each type of compass output from the
ADCU.
