Phone/Network Jacks (RJ11/RJ45 Connectors):
RJ connectors, as seen in Figure 34, are similar to the telephone connectors or
network jacks found in homes and businesses. These jacks are used on the ends
of RJ11 or RJ45 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.
Quick-connect Jack:
The display uses quick-connect jacks for the connection of the signal, the
temperature sensor and the connection to a mirror display. Three
input and one output quick-connect jacks are located on the back of
the primary display. When not in use, the attached dust cover
should be kept closed.

Quick-connect Jack
To attach the cable to a jack, match the configuration of wires in the
plug to the pattern in the jack. Push the plug in, then turn the outer
collar to lock it into place. Figure 35 illustrates the 6-pin quick-
connect jack.
Fiber Optic Cable:

Optic Cable
A fiber optic network transmits light (signal) through a glass fiber.
Because fiber optic cable is glass, the cable must never be bent. The
cable is usually a four-fiber cable, with two fibers used for display
communications and the other two saved for spares (Figure 36).
