RS422
One end of the signal cable should be terminated to the 6-position terminal block in
the display labeled “RS422 IN” (TB2). The opposite end is terminated at the signal
converter (Daktronics part number 0A-1127-0237) in the control room.
Figure 25: RS422 Layout
Note: RS422 cable must be installed so that it is separated from any source of
electrical interface. A minimum of a two-foot separation between the signal cable
and any power conductors is typically required, or the signal cable may be routed in
grounded metallic conduit. The signal cable must
not be routed in the same conduit
as the power conductors.
