3.7 Signal Termination from Computer to Display
Figure 22: Signal Termination at Display (Front View)
Figure 22 gives the general location of various control components of the display.
The location of the display controller and power termination panel may vary slightly
depending on the height of the display. Note: The AF-3150 is designed for quicker
connection to other displays, and to addition components such as a temperature
sensor or a client radio. Connection of the communication equipment to the primary
display can be done using a cable with a quick connect or can be wired directly to the
controller in that display. Depending on the number of displays and the
communication type ordered, the following cables may be provided with the
displays:
1. Interconnect cable from primary display to secondary display, length 4 feet.
2. Temperature sensor with quick connect cable, length 25 feet.
3. Client radio with quick connect cable, length 25 feet.

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 wired directly to the controller inside the display. The
non-quick connect 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 top
jack (J33) on the back of the display.
2. When connecting directly to the display, terminate the wire to the terminal
block in the J-box and the other end to the 6-position Phoenix plug on the
controller labeled “RS232 IN” (TB1). Drawing B-177662 and
Figure 24
below shows the terminal block wiring.
