3.3 Control Cable Requirements
3.3.1 RS/232
This cable is a 2-conductor shielded cable used to transmit a RS/232 signal (Daktronics
part number W-1117). This shielded cable should not be subjected to mechanical flexing
after installation. This cable is not for direct burial and should be routed in a dedicated,
grounded metallic conduit at the base of the display structure. This cable has a maximum
length of 25 feet.
3.3.2 RS/422
This cable is a 6-conductor unshielded cable used to transmit a RS/422 signal (Daktronics
part number W-1210). This unshielded cable consists of paired wires. They should not be
subjected to mechanical flexing after installation. This cable is not for direct burial and
should have one of the following routings:
1. In dedicated metallic conduit
2. In plastic conduit away from interference signals
3. Inside buildings - if cable is not in conduit, keep away from interference signals.
L
With interference signals, such as power conductors, intercom, etc., a two-
foot separation is typically required.
3.3.3 Modem
The modem option will use standard telephone cable routed through conduit. The local
telephone company will need to assist in this installation.
Ask the telephone company which colors are used by the TIP, and the RING for signal
hook up. U Note: The telephone lines must be dedicated lines and not run through a
switch board/communications system.
3.4 Signal Termination From Computer To Display

One end of the signal cable should be terminated to the 10 position terminal block in the display
labeled “DATA IN” (TB42). Drawing A-88427 is an example of the termination panels. The
other end is terminated at the J-box at the display structure. The laptop PC connects to the
J-box through the serial cable (refer to Drawing A-96058).
