422 Cable pin-outs
RS-422 allows multiple numbers of TriCoders to be "multi-dropped" off a
single 422 serial port. Maximum distance for RS-422 is 4000 feet. Using
the following pin-outs, you can make your own 422 "multi-drop" cables by:
1. Tying
T+
on the TriCoder end to the
R+
on the continuous 422 line.
2. Tying
T-
on the TriCoder end to the
R-
on the continuous 422 line.
