2 Mechanical Installation
Mechanical installation consists of lifting and permanently mounting the shot clocks,
control enclosure, and remote horn enclosure. Be sure that the installation complies with
local building codes.
Note: Daktronics assumes no liability for any installation derived from the information
provided in this manual or installations designed and installed by others.
Lifting the Display
Small Daktronics displays use two lifting straps that encircle the cabinet. It is
recommended to use a spreader bar with the straps.
Note: Daktronics assumes no liability for damages resulting from incorrect setup or lifting
methods.
Shot Clock Mounting
Reference Drawings:
Court View, BB-2160 & BB-2161 ...................................................................... DWG-4935896
Refer to DWG-4935896 for the approximate location to mount both shot clocks sizes on
the backstop.
• BB-2160 shot clocks are mounted behind and above the top center of the
backboard with included hardware. Due to game play, these shot clocks will be
exposed to a lot of movement and vibration. The brackets need to be designed to
minimize vibration and shot clock movement.
• BB-2161 shot clocks are mounted on the rear of the backstop, perpendicular to the
backboard, with included hardware.
Control Enclosure Mounting
IMPORTANT: The control enclosure must be located within 30' (9.1 m) of the shot clock.
Mount on the base of the backstop with four #10 self-drilling screws. Power and signal
from the control console will be routed to the enclosure.
Remote Horn Enclosure Mounting
Use two #10 self-drilling screws to mount the remote horn enclosure in an open location
so that sound is able to radiate. A 20' (6.1 m) pre-attached cable is included, but this
cable may be extended to mount the horn enclosure further away from the control
enclosure if needed.
Camera Mounting
Reference Drawings:
Assy; Camera Cable Holder............................................................................ DWG-1172138
If a camera is to be added (BB-2160), camera mounts accepting 2" (51 mm) pipe are
available; only one may be used at a time. A cable tray can be used to route camera
wiring down either side of the shot clock. Refer to DWG-1172138.
Note: Total weight of camera and mounting arm cannot exceed 50 lb (23 kg). Design
mounting brackets to accommodate both the shot clock and the camera.

other improper power conditions.
Installation Overview
Electrical installation involves routing power and control signal wiring through separate
conduit or wire ways.
Note: Control signal cable and some junction boxes are not provided as part of this
system and can be purchased locally or from Daktronics.
Power
Only qualied individuals should complete the electrical installation; untrained personnel
should not attempt to install these displays or any of the electrical components� Improper
installation can seriously damage the equipment and be hazardous to personnel�
Install a grounded receptacle near the equipment so that the power cord can easily
reach it.
Each shot clock control enclosure comes with a 120 or 240 VAC twist lock power plug
that must be attached to a 120 or 240 VAC power cord (by the customer) as follows:
• 120 VAC wiring: Connect black wire to copper terminal, white wire to nickel terminal,
and green wire to green terminal.
• 240 VAC wiring: Connect black wire to copper terminal, red wire to copper terminal,
and green wire to green terminal.
Grounding
All components of a display system – including but not limited to displays, control
equipment, and connected peripheral equipment – must be electrically grounded.
Only qualied individuals may perform electrical work, including verication of ground
resistance. Daktronics is not responsible for improper grounding or damage incurred as a
result of improper grounding.
Grounding methods must meet the provisions of all applicable local and national codes.
Inspect and verify all grounding methods meet the provisions of all applicable local and
national codes.
Proper grounding is necessary for reliable equipment operation and general electrical
safety. Failure to properly ground the display system may void the warranty, disrupt
operation, damage equipment, and cause bodily harm or death.

Power-On Self-Test (POST)
The display performs a self-test each time that power is turned on and the control
console is powered off or not connected. If the control console is connected and
powered on, the self-test does not run, and data from the control console is shown on
the display after a few seconds. Each self-test pattern will vary depending on the model,
the number of drivers, and types of digits.
Radio Settings
If a radio receiver is installed, the radio broadcast settings (“b1”) and the channel
settings (“C1”) are displayed in the game clock digits during the POST. These values must
match the settings in the control console. Refer to Radio Control (p�5) and Control
Console (p�2).
Signal Connection
Reference Drawings:
Connection Diagram; BB-21X0 & BB-21X1 ..................................................... DWG-4930529
Signal installation requires routing control cable from the control console to a signal
junction box (J-box) near the display, routing cable from the J-box to the control
enclosure, and routing the appropriate cables from the system components to the
control enclosure. At a minimum, use a paired, 22 AWG shielded cable (Daktronics part
# W-1077).
1� Connect the cable to a 1/4" J-box at the control console end.
2� Route the cable in conduit from the J-box on the control console end to a J-box near
the display.
3� Install the 1/4" phone plug (part # 0L-40683) to the display end of the cable. Be sure
to connect the cable shielding only in the J-box on this end. DO NOT connect cable
shielding at the J-box near the control console.
4� Insert the plug into the J31 SIGNAL IN jack on the front of the control enclosure.
5� Connect the shot clock(s), remote horn enclosure, and any optional light strip kits to
the appropriate jacks on the control enclosure as shown in DWG-4930529.
6� Connect a signal cable from the J-box to the J1, J2, or J3 jack on the back of the All
Sport 5000 console.
Also connect the shot clock start/stop switch (part # 0A-1196-0031) to the J7 jack on
the All Sport 5000.
Radio Control
Reference Drawings:
Schematic: 120V Control Enclosure ............................................................... DWG-4910448
Schematic: 240V Control Enclosure ............................................................... DWG-4910665
An optional radio system provides wireless control via 2.4 GHz signal. The radio transmitter
and receiver are not standard equipment. This setup requires a control console
equipped with radio transmitter as well as a radio receiver plugged into the J30 jack in
the control enclosure wiring harness using a 5-pin to 6-pin adaptor (part # W-2913). Refer
to the appropriate schematic drawing. The receiver unit is mounted internally to the front
panel of the enclosure.
