Connecting a WeatherStation to a Combiner
1. Purchase and install a PB1
50 WeatherStation and a Combiner (Part No.
AIR-033-800) following the manufacturer’s instructions.
2. Connect the adaptor cable that came with the Combiner between the
WeatherStation and the Combiner (see Figure B).
3. To connect the RD-30 to the Combiner, splice the open wire end of the RD-30
power/data cable to the Combiner’s NMEA Display Port cable. Splice the wires
together following the colors specified (see Table below). Make a marine grade
splice using solder and heat shrink tubing.
4. After making all the connections, plug the connector end of the Furuno power
cable into the RD-30 IN/OUT port.
