Phone/Network Jacks (RJ11/RJ45 Connectors):
RJ connectors, as seen in Figure 62, 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.
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 63 illustrates the six-pin quick-
connect jack.
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. A four-fiber cable
is shown in Figure 64. Figure 63: RS232/Six-
