3.1.1 Cables
The six conductor connector used
in the network is an industry
standard, RJ-11. This connector
can be found on many
telephones.
Electrical Installation

The cable used in the network is
a standard flat six conductor
telephone cable (standard
flipped cable). Refer to Figure
4. This cable has one end that is
the mirror image of the other end
(i.e. the cable is flipped). Refer to Figure 5 for a standard flipped cable.
Figure 4: Six Conductor RJ-11 Connector and
Cable
Notice in Figure 5 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 as 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.

3.1.2 Installing an RJ-11 Connector
Installing an RJ-11 connector on the end of the six conductor cable is a simple task
when the correct tools are used. The RJ-11 crimping tool (Daktronics part number
TH-1033) performs two separate steps.
Figure 6: Wire with
Outer Jacket Stripped
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 6.
