20 Electrical Installation
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 (Daktronics part number W-1242).
See
Figure 18 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
All of the scoreboard models in this manual require multiple drivers 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.
Refer to the component location drawings in
Appendix A for exact driver locations.
1. On the upper section, open the appropriate access panel to locate the bundle of
interconnect cable coming from the driver.
Note: Additional panels may be opened for easier access when routing the cable.
2. Route the interconnect cable through the hole in the bottom of the upper cabinet
through the hole in the top of the lower cabinet, and plug it into the driver.
3. With four-section scoreboards, be sure to also connect any plugs extending from the
right side of the left cabinets to the corresponding jacks on the left side of the right
cabinets.
4.6 Lightning Protection
The use of a disconnect near the scoreboard to completely cut all current-carrying lines
significantly protects the circuits against lightning damage. In order for this system to
provide protection, the power must be disconnected when the scoreboard is not in use.
The control console should also be disconnected from power and from the signal junction box
when the system is not in use. The same surges that may damage the scoreboard‟s driver can
also damage the console‟s circuitry.
