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.
