4.5.1 Connect the radar communications cable (NS003107) to the junction box
The free ends of the radar communications cable (NS003107) must be terminated in a junction box
(see the figure in the previous section). The junction box is not supplied.
The communications cable has a 0.41" (10.5 mm) diameter. The junction box must be waterproof and
large enough to contain a 20 way strip connector.
All cable entry points should use suitable grommets or glands to ensure that waterproofing is
maintained.
The table shows the wiring and pin details of the radar communications cable. The naming
convention for the bi-colored wires is primary color/stripe; for example, White/Orange refers to a
white colored wire with an orange stripe.
If the radar processor is connected through the 12-pin NMEA/Comms connector on the radar communications
cable (NS003107), then all of the NMEA 2 free end signals and grounds must be NO CONNECT in the junction box.
If a SmartCraft device is connected through the 8 pin SmartCraft connector on the radar communications cable
(NS003107), then all the RS-232 free end signals and grounds should be NO CONNECT in the junction box.
NMEA devices must be connected to an unused NMEA port on the connector strip.
The remote power signal configuration is explained in "Configure the remote power control for a
6000i or 6100i (common power source)" and "Configure the remote power control for a 6000i or 6100i
(different power sources)".
