Daktronics AF-3180-64-R,A - Manual (Page 37)

Using more than 10 feet of cable, and no Quick Connect
1. Run ½" conduit from the temp sensor location to a knockout on the back of
the first display. The cable must be routed through ½" metal conduit that
should be earth-grounded to protect the sensor and controller from lightning
damage.
2. Use a 2-pair, 22 AWG, individually shielded cable (Belden 5594,
Daktronics part number W-1234) to connect the sensor to the controller.
3. Disconnect the CAN temp sensor cable from the temperature sensor
terminal block in the CAN temp sensor housing. (0A-1151-0005)
4. Connect the desired length of cable from the temperature terminal block in
the CAN temp sensor housing through conduit to the display. The cable
length from the sensor to the display should not exceed 500 feet.
5. Terminate the cable to the 8-position terminal block in the display labeled
“CAN US/DS” (A31/TB4). Drawing B-177662 shows the terminal block
wiring.
