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 16 shows an
example of the LED bar test pattern that each digit performs.
Radio Settings
If a radio receiver is installed, the radio Broadcast and Channel settings will be displayed in
on the scoreboard during the POST. These values must match the settings in the control
console (refer to the manual listed in
Section 1.4 ). Refer to Section 5.9 for more information
on radio installations.
4.4 Signal Connection
For wired setups, route signal cable through
the rear of the scoreboard via conduit to the
signal surge arrestor card (
Figure 17) , located
just above the power termination block in the
driver enclosure.
At the SIGNAL IN terminal block, connect
the red signal wire to the positive terminal
and the black wire to the negative terminal.
Note: Be sure to properly connect the
shield (silver) wire to the SHIELD
terminal.
For signal cable, Daktronics recommends, as a minimum, single-pair, shielded cable, 22 AWG
(Daktronics part number W-1077). Two-pair shielded cable (part W-1234) is preferred.
