I'm installing a Garmin 17x antenna to an older Raytheon RL70 Chartplotter. The Raytheon manual reflects the wiring as follows Channel 1 NMEA data input (+ve); return (-ve) : Channel 2 NMEA data input (+ve); return (-ve). http://www.raymarine.com/SubmittedFiles/Handbooks/Radars/81206_1www.pdf
The Garmin manual reflects the wiring as Rx A(+), Rx B(-), Tx A(+) and Tx B(-). http://www8.garmin.com/manuals/2443_InstallationInstructions_Multilingual_.pdf Am I wrong to ass-u-me that Channel 1 input (+ve) connects to Rx A(+) and Channel 1 return (-ve) connects to Rx B(-), and so on??? And should I connect both Channel 1 & 2 to the GPS antenna?
Thanks!
