3.3 RJ Connector Cables
Two types of RJ connectors are used in
the display. There is the 6-pin RJ11 and
the 8-pin RJ45.
Figure 14 illustrates a
typical RJ11 connector. These
connectors can be found on many
telephones and LANs.

The cable used in the display are straight
through cables meaning that the wire to
pin one at one end is the same as pin one
at the other end, and so forth. When
installing a network, and on cables
exterior to the display, flipped cables are
often used. This cable has one end that is
the mirror image of the other end (i.e. the
cable is flipped). Refer to
Figure 15 for a
standard flipped cable.
Notice in Figure 15 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.
