4.4 Signal Connection
For wired setups, route signal cable through
the conduit knockout on the rear of the
scoreboard to the signal surge arrestor card
(Figure 15), located just above the power
termination block in the driver enclosure.
At the SIGNAL IN terminal block, connect
the red signal wire to the positive terminal
and the black wire to the negative terminal.
Note: Be sure to properly connect the
shield (silver) wire to the SHIELD
terminal.
For signal cable, Daktronics recommends, as a minimum, single-pair, shielded cable, 22 AWG
(part number W-1077). Two-pair shielded cable (part number W-1234) is preferred.
Fiber Optic
Another common signal communication method is fiber optic
cabling. A minimum cabling of multi-mode, 62.5/125 um, and
2-core fiber cable is recommended (part number W-1242).
See Figure 16 for the location of the fiber connector on a 16-
column driver. This method requires a signal converter between
the All Sport console‟s scoreboard output and the fiber optic cable
(not provided by Daktronics).
Multiple Driver Connections
Some models in the multi-section outdoor scoreboard line require multiple drivers in each
scoreboard section, and use a master/slave driver system. Master and slave drivers function
identically, but slave units lack the power termination block and signal surge suppression
card. When one section has multiple drivers, they simply plug into one another, and this is
done at the factory. Drivers between sections, however, require additional on-site connection
as described in Section 4.5.
Note: Scoreboards capable of displaying speed of pitch (SOP) have an additional master
driver. These models also require a separate signal connection (either wired or radio)
from a dedicated speed of pitch All Sport 5000 console. Refer to the Baseball Speed of
Pitch Systems Configuration Manual (ED-12224), available online at
www.daktronics.com/manuals , for more information about setting up an SOP system.
4.5 Power/Signal Connections Between Sections
Most multi-section outdoor scoreboards use a single power/signal interconnect cable
between a driver in the upper section and a driver in the lower section (Figure 17).
It is common for the top driver to be located behind the right-most HOME score digit with
the bottom driver located behind the right-most digit of the left-most set of digits. Refer to the
component location drawings in Appendix A for exact driver locations.
