Light Strip Controllers
Daktronics scorer’s tables equipped with optional End-of-Period (EOP) light strips require
an All Sport®5000 console to control them. Refer to End-of-Period Light Strip Kits (p�9)
for more information about installing optional light strips. For operating instructions, refer
to the All Sport 5000 Series Control Console Operation Manual (ED-11976), available
online at www.daktronics.com/manuals.

2 Mechanical Installation
All decisions regarding display setup must conform to the specications and guidelines
in this section. Read both the mechanical and electrical installation sections before
beginning any installation procedures.
Table Setup
Reference Drawings:
Mechanical Specs; ST-2363/2373 ................................................................... DWG-3462318
Move the table(s) to the desired location. This will typically be within 10' (3 m) of a power
outlet.
• If there is only one table, skip ahead to Tabletop Setup (p�7).
• If there is more than one table, rst refer to Multiple Table Connection (p�4).
Multiple Table Connection
If more than one scorer’s table is to be used as part of a single display face, they must
be lined up in the appropriate arrangement and attached to each other. One table
attaches to another using three latches on the right-hand side of the table (as viewed
from the rear). There is one latch in the cable tray (1), one latch on the rear of the caster
base (2), and one latch on the lower-front corner of the caster base (3). Refer to Figure 4
for the location and detail of these latches.

To attach the tables together, follow the steps below:
1� Look at the back side of the tables to determine the section numbering. Section
numbers are applied to the back of each table at the locations shown in Figure 5.
The farthest right table (when viewed from the rear) will typically be labeled “101”,
then the next table to its left will be “102”, and so on.
2� Position the two sections close together as shown in Figure 6.
Note: At this point, ensure the ip latches are not sticking out the side of the tables
prior to sliding the tables together, as this may damage the latches.
3� Slide the sections together as shown in Figure 7.

4� Latch all three latches on the left table to the right table (as viewed from the rear).
Refer to Figure 8 for illustrations of each latch properly connected.
Flip the hook end of the latch into the receiving slot on the adjacent table. Ensure
the tables are seated completely together to avoid over-pulling the latch and ip the
latch down into the locked position.
5� Repeat Steps 1–4 for all remaining tables.
Adjusting Latch Tension
The tension of the latches is pre-set at the factory. When engaged, the latches should
create a snug t. If there is a noticeable gap between the tables or if it is difcult to clasp
the latches shut, adjust the tension by following the steps below and referring to Figure 9.
1� Use a 5/16" wrench to loosen the nut holding the metal hook in place.
2� Turn the metal hook clockwise to tighten the latch or counterclockwise to loosen the
latch.
3� Ensure the metal hook is pointing straight downward and then tighten the nut.
