NEMA Bus

This is a picture of my NEMA Bus with all the cables going to the cockpit instruments. I found this one cable that is not connected to anything. Is that supposed to be like that? If so for what purpose?

NMEA 2000 busses require a terminator on each end of the buss. My guess is you are looking at the terminator. (BTW some "T" connections have a built in terminator. This is common for the cable up your mast to the wind instrument as the designers don't expect you to run two cables, one up and one down, but rather to start the buss at the wind instrument.) Note that all instruments come off the foot of the "T", never from the sides.
