Connecting the Antenna Power Cable
For single-switch convenience, the ADCU has been designed to
serve as a junction box between ship's power and the antenna
unit. Connect the antenna power cable to the red ADCU terminal
strip connector as shown in Figure 2-23.
Alternate Method of Providing Power to the Antenna (Optional)
Rather than using the ADCU as its power source, the antenna
unit can be connected directly to a separate 5-amp switch and
breaker if such a configuration is more convenient or if the
ADCU is placed more than 50 ft (15 m) from the antenna unit.
For example, this configuration would be preferred if you needed
2 ).
to be able to turn off the antenna while keeping the GyroTrac
powered on.
If the power cable is longer than 50 ft (15 m), be sure to verify the
voltage at the antenna to ensure that there is sufficient power to
drive the antenna under load (11-16 VDC). If not, carefully
increase the voltage to the antenna unit to compensate for any
drop in power over the length of the cable and ensure that the
voltage reaching the antenna unit is between 11 and 16 VDC.
Do NOT connect the antenna to vessel power until all other
wiring is completed. Also, be sure to follow the same power
wiring guidelines provided in "Connecting the ADCU to Vessel
Power" on page 37.
