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

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.

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. 
For additional information about this option, contact a Daktronics representative. For 

complete instructions on setting up radio control, refer to the
