4. Mate-n-Lok
™ Connectors:
Figure 12: Mate-
n-Loc Connector
The Mate-n-Lok connectors found in the displays are
white and come in a variety of sizes.
Figure 12 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 (RJ Connectors):
RJ11 or RJ45 connectors, as seen in Figure 13 on the lower
right, are similar to those on telephone and LAN
connectors found in homes and businesses. They can be
used on the ends of either flat cable or CAT5. 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. Quick Connect Jack:
The display uses quick connect jacks for the connection
of such things as the temperature sensor, a client radio,
and connection of the primary to the secondary or mirror
display. The quick connect jacks are located on the back
of the display and when not used the attached dust cover
should be kept closed.

pin Quick Connect Jack
To attach the cable to a jack, make sure to line up the
plug to match the jack, push the plug in then turn the
outer collar to lock in place. Figure 14 illustrates the 6-
pin quick connect jack.
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 from the j-box at the base of the
sign structure to the display. This cable has a maximum length of 25 feet (7.6
meters).
