the red and black wires to power your display unit. Attach the red wire
(+) to an accessory switch or power bus connected to a 12-volt battery.
Connect the black ground wire (–) to the battery negative post.
Tip
If possible, keep the power cable away from other boat wiring, espe-
cially the engine's wires. This will provide the best isolation from
electrical noise.
If the cable is not long enough, splice #16 gauge wire onto it. Make sure
to attach the in-line fuse holder to the red lead as close to the power
source as possible. Make sure it is fused with a 3-amp fuse.
2. The blue and green wires (Com port 2) can be used to exchange GPS
position data with any NMEA 0183-compatible device. Connect the blue
(TX) transmit wire to the receive (RX) wire from the NMEA 0183 de-
vice. Now connect the green (RX) receive wire to the transmit (TX) wire
from the NMEA 0183 device. There is no ground wire, so the
NMEA 0183 device MUST be grounded to the same source as the
display unit.
3 If you are powering a NMEA 2000 network or an LGC-3000 GPS an-
tenna, you must connect the NMEA 2000 power cable. Attach the
NMEA 2000 red wire (+) to an accessory switch that is connected to the
same 12-volt power source as the display unit power cable red wire (+).
Be sure to use the 3-amp fuse. Connect the black wire (–) to the nega-
tive battery post.
Plug the RIM 300 Data Cable into the NMEA/COMMS port on the back
of the radar processor
4. Plug the RIM 300 radar data cable into the NMEA/COMMS port on
the radar processor box.
5. After all wires and cables have been connected and all unused wires
insulated, insert the RIM 300 cable plug in the power/data receptacle
on the back of your display unit.
