Copper Signal
Route copper signal cable through the
conduit knockout on the rear of the display
to the signal surge arrestor card ( Figure 8 ),
located in an enclosure.
At the
SIGNAL IN terminal block, connect
red signal wire to positive (+) and black
signal wire to negative (–).
Note: Ensure shield (silver) wire is properly
connected to the SHLD terminal.
To connect signal to nearby displays, route
signal wire in conduit from SIGNAL OUT of
the signal surge arrestor card in the primary
display to SIGNAL IN on the signal surge
arrestor card in the secondary display.
At a minimum, single-pair, shielded cable,
22 AWG (part # W-1077) is recommended.
Two-pair shielded cable (part # W-1234) is preferred.
Fiber Optic Signal
Route fiber optic signal cable through the
conduit knockout on the rear of the display.
The fiber optic cable is terminated to a male
ST-type connector and plugged into the J3
jack on the fiber card ( Figure 9 ), located in
an enclosure.
A minimum cabling of multi-mode, 62.5/125
um, and 2-core fiber cable is recommended
(part # W-1242). This method requires a
signal converter between the All Sport
console’s scoreboard output and the fiber
optic cable ( not provided by Daktronics ).
To connect signal to nearby displays, route
*copper* signal wire in conduit from SIGNAL
OUT of the fiber card in the primary display
to SIGNAL IN on the signal surge arrestor
card in the secondary display.
