Route power and signal cables into the scoreboard from the rear. There are two
knockouts for conduit connection in the back. All power and signal wiring
terminates at the driver enclosure.
Drawings A-178197
and
A-178235
illustrate the
16- and 8-column drivers used in Daktronics outdoor LED scoreboards.
To gain access to the driver enclosure, open the access door or digit panel and
remove the cover from the enclosure. Refer to the component locations drawings for
the access location for the scoreboard.
Connect power and signal cables at the appropriate
locations on the driver enclosure panel, shown in
Drawings A-178197
and
A-178235
.
Figure 7: Power Terminal Block
The conventional power termination panel has been
eliminated from Daktronics outdoor scoreboards; the
power feeder circuit connects directly to a terminal
block in the driver enclosure, as shown in
Figure 7
.
The terminal block is located in the lower right corner
of the enclosure. Connect the power wires as shown in
the illustration. Refer to the driver engineering
drawings and to the schematics listed at the beginning
of this section for additional wiring details. The
schematics
include a detailed illustration of the power
termination.
Note:
Driver enclosures in some earlier Daktronics scoreboards included a 120 V
power receptacle. There is no 120 V receptacle in Generation III displays. If you
want power to operate the control console at the scoreboard for troubleshooting,
Daktronics recommends that you have the installation electrician provide a 120 V
outlet close to the disconnect box specifically for this purpose.
Route signal cabling to the signal surge arrestor card in the upper left corner of the
driver enclosure. The connections are labeled to permit easy installation. At the
Signal In terminal block on the PCB, connect the red signal wire to the positive
terminal, the black to the negative
terminal, and the shield (silver) wire to
the shield terminal.
Note:
It is important
that the shield wire is properly connected
to the shield terminal on the signal surge
arrestor card.
Figure 8
illustrates the
signal surge arrestor card and
connectors.
Figure 8: Signal Surge Arrestor Card
For signal cable, Daktronics
recommends, as a minimum, single-pair,
shielded cable, 22 AWG (Daktronics
part number W-1077). Two-pair shielded
cable (Daktronics part W-1234) is
preferred.
