RS422 Interconnection
The quick connect cable is the most common method
of terminating signal between two displays. The cable
goes from the RS422 OUT on the primary display to
the RS422 IN on the secondary display as shown in
Figure 32 .
Figure 32: Display Interconnection
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. Refer to
Figure 33 . When not
using the quick inter-connect cable, wires must be
in conduit.
