4.3 Power-On Self-Test (POST)
The scoreboard performs a self-test each time that power is turned on and the control console
is powered off or not attached to the scoreboard. If the control console is attached and
powered on, the self-test does not run, and data from the control console is displayed on the
scoreboard after a brief period of time. Each scoreboard self-test pattern will vary depending
on the scoreboard model, the number of drivers and types of digits.
Figure 9 shows an
example of the LED bar test pattern that each digit performs.
Radio Settings
If a radio receiver is installed (see Section
‎
6.2 ), the
radio broadcast settings (“b1”) and the channel
settings (“C1”) will be displayed in the Home and
Guest or clock digits (
Figure 10 ) during the POST.
These values must match the settings in the
control console (refer to the appropriate control
console manual listed in
Section
‎
1.1 ).
4.4 Scoreboard Signal Connection
Signal installation (for systems without radio control) requires routing control cable from the
scoreboard control console to a signal junction box (J-box) near the display. See also
Drawing
A-28124 in Appendix E and Drawing A-125316 in Appendix D .
1. At a minimum, use a paired, 22 AWG shielded cable (Daktronics part # W-1077) and
connect the cable to a
dual

/

" J-box at the control console end.
Using a dual J-box for separate Main and Aux scoreboards lets operators control
several displays with one controller, and they can also switch jacks to control
individual boards using multiple controllers.
2. Route the cable from the J-box on the control console end to a J-box near the display.
3. Install the

" phone plug (Daktronics part # 0L-40683) to the scoreboard end of the
cable. Be sure to connect the cable shielding only in the J-box on this end.
Note: DO NOT connect cable shielding at the J-box near the control console.
4. Insert the plug into the Signal In (J31) jack located on the top of the scoreboard.
5. Connect a signal cable from the J-box to the J1, J2, or J3 jack on the back of the All
Sport 5500 console.
If using a Main Clock Start/Stop Switch (0A-1166-0003), connect it to the J7 jack on
the All Sport 5500 console.
