RS422 Interconnection
The Quick Connect cable is the most common method of terminating signal between
two displays. The ten-foot cable goes from the RS422 OUT on the first display to the
RS422 IN on the second 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 of the correct
length is used. One end will connect at
the “RS422 OUT” 6-position controller
board terminal block (A31-TB3) in the
first display, and terminate on the
“RS422 IN” 6-position controller board
terminal block (A31-TB2) on the second
display. When not using the provided
quick connects cable, the cable should be in conduit.
