Have had the interface cable on my SHO for quite sometime & never a problem. Last week it worked fine. Went to the lake yesterday & nothing worked on my HDS for the NEMA2000. No RPM, WP, etc, nothing. Anyone have any ideas as to the problem or a solution. I have checked everything on the NEMA network, (Yamaha cable, live well temps, LGC 4000 HS). nothing shows up. Before I could power up the Lowrance (HDS12 Gen 3), turn the ignition on, go to the system, network, device list and it would show the SHO & the LGC. Now there is nothing but HDS. I have checked everything I know to check & can't find anything wrong. Fuses are good, power to the NEMA backbone, etc. Is there anyway to check the interface cable to determine if it is good or just went south. Any help or ideas would be greatly appreciated.
