™
Connectors:
Figure 12: Mate-n-
Loc Connector
The white Mate-n-Lok connectors found in the signs come in
a variety of sizes.
Figure 12
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 13
shows this connector.

6. Phone Jacks (RJ11 Connectors):
RJ connectors, as seen in
Figure 14
, 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 to
the plug before inserting it into the jack. This paste will protect both
the plug and the jack from corrosion.
7. Quick Connect Jack:
The display uses quick connect jacks for the connection of the signal
termination enclosure, the temperature sensor and possible
connection to an echo display. There are three input and one output
quick connect jacks located on the back of the primary display, and
when not used the attached dust cover should be kept closed.
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.
