An RS232 controlled display requires the use of a J-box within 25 feet of the display
as shown in
Figure 23
. From the J-box to the display, the signal may be connected
using a quick connect cable or directly wired to the controller inside the display. The
cable from the J-box to the display must be routed though conduit. Do not run signal
and display power through the same conduit.
1. If using a quick connect cable, connect from the J-box to the RS232 jack
(J33) on the back of the primary display.
2. When connecting directly to the display, terminate the 2-conductor shielded
cable to the terminal block in the J-box and the other end to the 6-position
terminal block on the controller labeled “RS232 IN” (TB1).
Drawing B-
177838 and
Figure 24
below shows the terminal block wiring.
The controlling laptop computer connects to the J-box through the serial cable (refer
to
Drawing A-174341 ).
