A display that is controlled using RS422 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 or to a plug that is connected to the Quick
Connect at 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 for system layout.
1. If using a quick connect cable, connect from the signal converter to J32 on
the back of the display.
2. When connecting directly to the display, terminate one end at 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). Drawing
B-
177662 shows the terminal block wiring.
