I have a Raytheon RL 80RLC radar plotter installed in 1999. Supplying info to this MFD is a Autohelm heading sensor using the NEMA 0183 protocol. I recently installed a Garmin 740 plotter. The Garmin unit has 2 NEMA 0183 inputs and outputs. I have a Standard Horizon VHF with AIS which is connected to two of the Garmin outputs and one of the inputs.
I would like to supply heading info to the Garmin unit using the heading sensor. The heading sensor has 3 wires coming out of it. A red power wire connected to +12v DC, a yellow wire connected to the Channel 2 NEMA plug of the Raytheon MFD and a silver (shield) wire that goes to battery ground and also to a different plug on Channel 2 NEMA on the MFD.
Can I splice (solder) a new wire onto the existing yellow wire coming out of the heading sensor and route that to the free input wire on the Garmin unit and expect the Garmin unit to receive heading info?
Note: I don't want to mess up the heading info to the Raytheon MFD because both the radar and plotter need this info.
