I don't see a better place to post this, so here goes... I have several RS485 runs going through underground conduits. The local inspector is demanding that we use UL Listed direct burial cable, which I'm not finding anywhere. I can find many cables that are 100?, but I have several long runs at the end that are the proper 120? cable, and I'm concerned with mixing impedances. Does anyone know of proper 120? RS485 (Can bus, DMX, etc...) direct burial cable that's listed? Thanks, Larry
