RIM 300 Installation
The RIM 300 will replace the power cable that came with your display unit. Your RIM 300 has
three cables branching out from the cable plug, which include: radar data cable, display unit
power cable and NMEA 2000 power cable.
NOTE:
You will need to purchase a SIMRAD heading sensor for the Radar Overlay feature to work
properly.
You MUST remove the power cable that came with your unit and replace it with the RIM
300 to complete this installation.
WARNING:
Even though the RIM 300 is replacing your original power/data cable, you must follow
the same rules, cautions and warnings for powering the display unit and a NMEA 2000
network or LGC-3000 antenna module. These details are described in the display unit
manual and the LGC-3000 instruction sheet. Failure to follow all power connection
instructions and fusing requirements could result in damage to your equipment and
injury to you. The RIM 300 radar data cable is connected to the radar processor. Radar
processor installation is covered in the Radar Installation manual.
• The RIM 300 works from a 12-volt DC battery system. The display unit power cable has
four wires: red, black, blue and green. You will use 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.
If possible, keep the power cable away from other boat wiring, especially 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
• 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 device. 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.fused with a 3-amp fuse.
