Modem
The modem option will use standard telephone cable routed through a conduit. The
local telephone company will need to assist in this installation.
Ask the telephone company which colors are used by the TIP and the RING for
signal hook up.
Note: The telephone lines must be dedicated lines and not run through a switchboard
system.
Fiber Optic
This cable is a 4-fiber cable (Daktronics part number W-1376). Two fibers are used
for display communications and the other two are saved for spares. The cable may be
either direct burial or routed in conduit but should not be subjected to mechanical
flexing. The maximum length of a fiber optic cable is 2,000 feet (611.6 meters).
Radio
The Server radio connected to the computer requires a six-conductor 18 AWG cable
to be wired from the J-box converter to the Outdoor Server. This wire needs to be in
conduit when exposed to outdoor conditions. The maximum distance from the J-box
to the Server radio is 1000 feet (611.6 meters).
The Client radio at the display comes with cable that is rated for outdoor use and
does not need to be in conduit.
3.3 RJ Connector Cables
Figure 18: 6-Conductor RJ11 Connector and
Cable
The connector used for RS232 input to the display is
an industry standard, 6-pin RJ11. 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 18 on the right. This cable has one
end that is the mirror image of the other end (i.e., the
cable is flipped). Refer to
Figure 19 below for a
standard flipped cable.
Notice in Figure 19 , at the bottom , 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.
