Connecting External Devices to the ADCU
(Optional)
GyroTrac can be integrated with many types of onboard
equipment, including autopilots, radars, remote displays,
plotters, global positioning systems (GPS), and computers. All
connections between the ADCU and external devices are made at
the terminal strip connectors located on the rear of the ADCU.
Follow these guidelines when wiring additional equipment to the
ADCU:
• Make certain any additional equipment complies
with NMEA Standard 2.2.
• Data conductor wire should be minimum 18 AWG
(0.75 mm
2
), twisted pair, stranded, tinned marine
cable.
• Do not use cables with a wire diameter larger than
12 AWG (2.5 mm
2
), as this is the largest size the
ADCU connector plugs can accept.
• The cable provided with the optional KVH
rotating card display is fully compatible with
GyroTrac requirements. Note that cables to other
external devices should follow the manufacturer’s
recommendations.
• For power cable specifications, refer to Table 2-2
on page 10.
As noted in Figure 2-21 on page 32, the output for Serial Ports 2
and 3 can vary from 4800 baud to 9600 baud. This is determined
automatically based upon the selected output. Serial Port 1
provides 4800 baud output only.
When the TracVision G6 antenna is connected to the GyroTrac
system, GyroTrac Serial Port 3 will not be able to provide output
to other equipment. Serial Port 3 will only provide outputs if the
antenna unit is disconnected from the ADCU and GyroTrac is
configured to operate as a stand-alone system as described in
“Selecting TracVision or GyroTrac-only Operations” on page 78.
Connecting the Rotating Card Display (Optional)
For complete instructions on properly wiring the optional
rotating card display, refer to Appendix D on page 137.

If the ADCU is receiving data from
a ship’s gyro, all compass outputs
are automatically configured as
True North and cannot be set to
Magnetic.
