The RS422 controlled display requires the use of signal converter (0A-1127-0237)
near the computer. From the signal converter, cable is run to the surge board
assembly in the display. The cable from the signal converter to the display must be
routed though conduit.
Do not run signal and display power through the same
conduit. Refer to Drawing A-174135 and
Figure 24
for system layout.
1. If using a quick connect cable, connect from the signal converter to a
junction box at the display, and from there to J32 on the back of the display
2. When connecting directly to the display, terminate one end at the signal
converter and the other end of the wire to the 6-position terminal block on
the surge board assembly labeled “RS422 IN” (A34-TB1). The connection
from the surge board to the controller is already completed. Refer to
Figure

and Drawing B-177662 for the terminal block wiring
