Interconnect Harness Connections
All multi-section football and soccer scoreboards use an interconnect harness as a
connection between the digits of the top section and their corresponding driver in the
lower section. Typically, one driver runs the top section of the board, while the other
driver runs the bottom section, but only the top section digits use the interconnect
harness. Cabling runs from the individual digits to a common point in the upper
scoreboard section, and the harness drops through the bottom of the scoreboard
cabinet to connect to the driver in the lower section. (At shipping, the interconnect
harness will extend approximately 7' from the bottom of the upper section. Open the
access panel to the lower driver, pull the interconnect harness through the hole in the
top of the lower cabinet, and plug the harness into the appropriate driver connection.)
Figure 9: Interconnect Harness Connections with Digit Designation
Figure 9 illustrates the interconnect harness connection.
On some larger four-section scoreboards, BA-2006, BA-2007, BA-3718 and BA-
3724 the digit interconnect harnesses plug directly into drivers in the upper left
section of the scoreboard.
Figure 10: Scoreboard Interconnect Harnessing
Because the four sections of these scoreboards are shipped separately and joined
onsite, care must be taken to properly route the interconnect cables. Refer to Figure
10 and follow this general procedure to connect the digit harnesses.

from the tops or sides of Sections B, C, and D. These are the digit interconnect
