Mate-n-Lok

Connectors:
The Mate-n-Lok connectors found in the displays are white and come in a
variety of sizes.
Figure 11 on the right illustrates a four-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. Phone Jacks (RJ11 Connectors):
RJ connectors, as seen in Figure 12 on the lower right, are similar to the
telephone connectors found in homes and are used on the ends of flat RJ11
cable. 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 to the plug before
inserting it into the jack. This paste will protect both the plug and the jack
from corrosion.
6.
Six-Pin Insulation Displacement Connector
The six-pin connectors found in the display are keyed connectors, meaning
that they will only go together one way and should not be forced. To
remove the connector squeeze the plastic tab and gently pull the plug from
the jack.
3.2 Control Cable Requirements
RS-232
This cable is a 2-conductor shielded cable used to transmit an 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 sign structure. This cable has a maximum length of 25 feet.
RS-422
This cable is a 4-conductor shielded cable used to transmit an RS-422 signal (Daktronics part number
W-1234). This shielded 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:

In dedicated metallic conduit

Inside buildings

if cable is not in conduit, keep away from interference signals.
With interference signals (such as power conductors, intercom, etc.) typically a two-foot separation is
required. The maximum length of an RS-422 signal cable is 4,000 feet (1.22 km).
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 connections.
Note: The telephone lines must be dedicated lines and not run through a switch board/communications
system.
