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 3.5.
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.
3.5 Power/Signal Connections Between Sections
Refer to the component location drawings attached to the product specification sheets listed
in Appendix A for exact driver locations when connecting multiple scoreboard sections.
Two-Section Models
Open the appropriate access panel on the bottom section to locate the coiled bundle of
interconnect cable coming from the driver, then route and connect the cables as described
below and shown in Figure 20.
Note: Additional panels may be opened for easier access when routing the cable.
Route the 5-pin interconnect cable from the Bottom Section up into the Top Section, and
connect the J43 jack to the P43 plug.
Note: In the MS-2009 and FB-3010, the top section driver is A2. In the MS-2918, the top
section driver is A3.
For the FB-3010, MS-2009, SO-2011, and SO-2043 only, route the interconnect cable from
the Top Section down into the Bottom Section, and connect the P42 plug to the J42 jack.
For the BA-2025 and BA-2027, route the 5-pin interconnect cable from the Bottom
Section up into the Top Section, and connect the P42 plug to the J42 jack (Figure 21).
