Daktronics AF-3165-34-RGB - Manual (Page 31)

3.7 Signal Termination from Computer to Display
The AF-3165 is designed for quicker connection to other displays and other
additional equipment. Connection of the first display to the control equipment needs
to be wired to the controller, modem, fiberboard, or surge suppression card in that
display. Depending on the display type ordered, the following cables may be
provided with the display:
1. Interconnect cable from Primary to Secondary, length 4 feet
2. Interconnect cable from Primary to Mirror, length 6 feet
3. Temperature sensor with quick connect cable, length 25 feet
4. Displays using radio, the quick connect cable with Client, length of 25 feet

The RS232 controlled display requires the use of a J-box within 25 feet of the
display. 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. A 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 the wires at the J-box and plug the
quick connect into J33 on the back of the display
2. When connecting directly to the display, terminate one end at the J-box and
the other end of the wire to the 6-position terminal block on the controller
labeled “RS232 IN” (A31-TB1). Refer to
Figure 23 and Drawing B-177662
for the terminal block wiring, and Drawing B-177838 for the controller
termination locations
