?Warm Tips? 1) Always have the terminators on the ends of the backbone to get NMEA 2000 successfully work. 2) NMEA 2000 has to be powered on its own by the power node. ?ALL-Included Component? Comes with EVERYTHING required to build a NMEA 2000 network: 1*power cable (N2K-PWR-RD, with power node), 2* T-connectors (N2K-T-RD0), 2* network terminators (TR-120M-RD, TR-120F-RD), 2*extension cables (2-ft N2K, 15-ft N2K). ?Premium Quality? Make of top-quality materials and finished with matte black, the network starter kit is oil resistant, seawater resistant, waterproof, anti-rust, promising long service lifespan and superior performance with stable network connetion. ?Practical Design? T-connectors serves as the Essential opponent to build a NMEA 2000 network, connecting the drop cable or device to the network backbone. Use 2-ft and 15-ft extension cable to expand the backbone, extending the cable run between a network device and a NMEA 2000 network. Terminators suppress any single reflection that could possibly get your network down. Holes on the top center of the Tee for screwing or hanging, which could easily keep the backbone nice and straight. ?Compatible With?
