8 Electrical Installation
Auto Off
The PC-2001 features an Auto Off function, which will automatically turn the unit off in
response to two conditions:
1. Idle Timeout – If the display is not plugged into a transformer, and not in program 8
or 9 (time of day), and has been idle for 1 hour (not counting, no switch activity, no
signal input), the display will sound the horn and flash the digits 10 times before
turning itself off. Pressing any switch will reset the one hour timer.
2. Low Battery – This feature prevents the PC-2001 from running its battery completely
dead and destroying the battery. When the battery has dropped below a minimum
level, the unit will begin sounding the horn once per second as a warning. If the unit
is not plugged into the transformer for recharging within about one minute, the unit
will automatically turn off.
To turn the PC-2001 on after an Auto Off has occurred, turn the power switch off, wait a few
minutes, and then turn it back on. In the case of a low battery, be sure to plug the display into
a charger before continuing use.
3.2 Signal
The PC-2001 is designed as a standalone timer without the need for signal cable from control
consoles. However, it is still possible to connect signal in from Daktronics All Sport
® scoring
consoles and OmniSport ® 2000 timing consoles, and signal out to multiple displays. For signal
cable, Daktronics recommends, as a minimum, single-pair, shielded cable, 22 AWG
(Daktronics part # W-1077). Two-pair shielded cable (part # W-1614) is preferred.
