Follow these steps to wire the belowdecks
equipment (see page 39 for a complete wiring
diagram).
Connect the Antenna Power/Data Cable
a.
First dress the power/data cable from the
antenna. Strip back the insulation of each
wire approximately 1/4" (6 mm) and gently
twist each wire to ensure a good electrical
connection.
b.
Connect the antenna power/data cable to the
supplied 16-position terminal strip connector
as shown in Figure 25.
c.
Plug the terminal strip connector into the rear
panel of the CommBox-ACU.
Connect a NMEA 0183 Talker
a.
Connect a NMEA 0183 talker (customer-
supplied) to the supplied 2-position terminal
strip connector as shown in Figure 26. Make
sure the device is configured to transmit one
of the following messages at 4800 baud to
provide true or magnetic heading:
• $--HDG
• $--HDM
• $--HDT
• $--OSD
• $--THS
• $--VHW
NOTE:
The system does not accept heading messages
that conform to the NMEA 2000 standard.
b.
Plug the terminal strip connector into the rear
panel of the CommBox-ACU.
