Notice below 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.

does not
include the conduit. Knockouts will be provided for power and
signal. Separate conduit must be used to route:
·
Power
·
Signal IN wires
·
Signal OUT wires (if signal is required for another display)
The conduit holes are located at the bottom right (rear view) of the back of the
display (refer to
shop drawings
located within
Appendix C
).
To access the knockouts, release the face panel latches using an 8mm Allen wrench
(provided by Daktronics). Open the face panel.
Caution:
The door will swing up.
Remove the bottom left module (front view) to reach the knockouts (refer to
Section
4.3
to remove a module).
Punch or drill out the desired knockouts. Be careful that none of the internal
components are damaged.
Attach the conduit and route the power and signal cables.
Refer to
Drawing A-88427
for a picture of the power and signal termination panels.
For displays with more than one face, signal and temperature sensor wiring between
displays can be routed through the same conduit.
