Electrical Installation 3-2
3.2 Signal
Cables
The conductor connector used in the
network is an industry standard, 6-pin
RJ-11 or an 8-pin RJ-45. This
connector can be found on many
telephones and LANs.
The cable used in the network is a
standard flat six-conductor telephone
cable (standard flipped cable ). Refer
to Figure 13. This cable has one end that is the mirror image of the other end (i.e. the cable is
flipped). Refer to Figure 14 for a standard flipped cable.
Notice in Figure 14 that the color code on one connector must be made the opposite on the other
connector. When installing a network, it is not easy to remember in which direction the previous
end was oriented. One simple way to avoid confusion is to standardize the color code, having one
color for the connector going into the output of a sign and the opposite color for a connector going
into the input of a sign. This will help ensure correct cabling since cables are always installed from
the output jack of one sign to the input jack of the next sign.
Installing an RJ Connector
Installing an RJ connector on the end of the conductor cable is a simple
task when the correct tools are used. The RJ crimping tool (Daktronics
part number TH-1033) performs two separate steps.
First, use the crimping tool to strip the outer insulation from the inner
wires. This does not result in bare wires since only the gray outer jacket is
removed. After correct stripping, the wire will appear as shown in Figure
15.
The crimping tool is then used to crimp the RJ connector onto the cable. The RJ connector is
locked into a special socket in the tool. The stripped wire is inserted into the RJ connector. Finally,
the tool is squeezed like a plie rs to crimp the connector onto the wire. This completes the
installation of an RJ connector onto the wire.
