• The quick connect cable is the most common
method of terminating signal between two
displays. The four-foot cable goes from the
RS422 OUT (J34) on the primary display to
the RS422 IN (J32) on the secondary display.
• If the displays are not back-to-back, or are
too far apart for the quick connect
interconnect cable to reach, a 4-conductor
shielded cable can be used. One end will
connect at the “RS422 OUT” 6-position
terminal block (TB3) on the controller of the
primary display, and the other end of the
cable will terminate on the “RS422 IN” 6-
position terminal block (TB2) on the controller of the secondary display.
