Phone/Network Jacks (RJ11/RJ45 Connectors):
RJ connectors, as seen in Figure 49, 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.

Connector
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:
Figure 50: RS232 6-pin
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.
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 50 illustrates the 6-pin quick-
connect jack.

Optic Cable
Fiber 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 51).
