Rt is the termination resistor
typically used for RS-422 differential
connections. If these termination
resistors are not internal to the
controller, they should be installed
externally at the connector. If
these are not specified or included
with the controller, use 1K OHM
resistors.
Tie back and insulate unused
A-, B- and Z- wires.
