does anyone on here have any experience connecting two chartplotters via an ethernet cable? I have a lowrance LCX 112 and lowrance HDS. I just installed a new transducer and I would like to use the older LCX as a screen to display either sonar or gps. I have been told multiple times that this is possible so I just need to figure out how to display it. I have the transducer running into the HDS and an ethernet cable that runs between the HDS and the LCX--how do i choose to display either gps or sonar data on the LCX display?
