Lowrance NAC-MRD2MBL NMEA 2000, NMEA2k, N2K Network GPS 5 Pin Red Male 5 Pin Blue Male 2 Ft Cable

The 127-04 NMEA 2000 adapter cable for connecting Lowrance NMEA 2000 devices with a 5-pin male red connector to a 5-pin male blue connector

It's important to realize the association of the colors red and blue when wiring devices for NMEA-2000 networks. These colors were only used by Lowrance. Years ago Lowrance's plugs used to be color coordinated. What Lowrance calls red are now actually a black plug. These plugs are pretty much the standard for NMEA-2000 networks. What Lowrance calls blue is their own style of connector used only by them on earlier NMEA-2000 GPS networks.
