4. Mate-n-Lok
ä
Connectors:
The white Mate-n-Lok connectors found in the signs
come in a variety of sizes.
Figure 15 on the right
illustrates a five-pin Mate-n-Lok connector. To remove
the plug from the jack, squeeze the plastic locking clasps
on the side of the plug and pull it from the jack.
5. Fiber Optic Connectors:
A fiber optic cable has a “twist-on” connector at each
end. To remove the fiber plug, push it toward the board
and twist it counter-clockwise until you can pull the plug
from the jack.
Figure 16 on the right shows this
connector.
6. Phone Jacks (RJ11 Connectors):
RJ connectors, as seen on the lower right in Figure
17 , are similar to the telephone connectors found in
homes. In order to remove this plug from the jack,
depress the small clip on the underside of the plug.
Before replacing an RJ connector, spray it with DeoxIT
™
contact cleaner to remove any foreign matter that may
cause signal problems. In addition, apply a generous
amount of CaiLube
™
protector paste in the plug before
inserting it into the jack. This paste will protect both the
plug and the jack from corrosion.

3.2 Control Cable Requirements
RS232
This cable is a 2-conductor shielded cable used to transmit an RS232 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 sign structure.
This cable has a maximum length of 25 feet.
RS422
This cable is a 6-conductor shielded cable used to transmit an RS422 signal
(Daktronics part number W-1210). This shielded cable consists of unpaired 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:
•
In dedicated metallic conduit
•
Inside buildings-if cable is not in conduit, keep away from interface signals
With interface signals, (such as power conductors, intercom, etc.) typically a two-
foot separation is required. The maximum length of an RS422 signal cable is 4,000
feet (1.22 km).
