18 Electrical Installation
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 14 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
the clock digits 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 15) , 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.
