Power
Power for the display is provided in two ways: via standard 120 VAC line, or by means
of two sealed lead-acid DC batteries. Daktronics supplies two 12 V batteries, rated at
28 ampere hours (A/H), as original equipment. Refer to Section 5: Battery Care and
Charging (p.7) for information on battery care and use of the on-board battery
charger.
The provided 8' (2.4 m) 120 VAC power cord plugs directly into the three-prong power
receptacle, located on the side of the display. Any time 120 VAC power is connected,
the internal charger operates; however, the system will not overcharge the batteries.
When the power cord is not connected, the display runs on battery power.
Displays are shipped ready for use. The battery charger is factory-mounted in the display,
and all internal wiring is in place and connected to the driver and batteries.
A control switch on the side of the display activates power to the internal components.
• Flip the switch
ON (up) for display operation.
• At all other times, keep the switch in the OFF (down) position.
Whether or not the display is operational, its batteries will continue to discharge any
time the switch is in the ON position. Leaving the switch ON when the display is not in use
could completely discharge and damage the batteries.
Keep the display plugged in to a 120 VAC power source during storage. Battery life
is enhanced by keeping the batteries fully charged. Typically, batteries will be fully
charged in about 12 hours and will give about 14 hours performance on a full charge.
Wired Signal Connection
Connect a signal cable with 1/4" phone plugs from the signal jack on the side of the
display to the J1 , J2 , or J3 jack on the back of the All Sport 5000 console (or J1 / J2 on the
All Sport 1600). Daktronics offers several pre-terminated signal cable lengths. Refer to
Replacement Parts (p.17) .
Wireless Radio Receiver Installation
Note: A control console equipped with an optional radio transmitter is required for
wireless communication.
The All Sport radio receiver is typically held in place with adhesive-backed, hook-and-
loop fastener strips, and when ordered as original equipment may already be installed.
The only installation required is attachment of the radio antenna, which may have been
shipped separately to prevent damage.
If the radio receiver is not already installed:
1� Access the inside of the display by unlocking the latches securing the front access
panel or by removing a digit panel.
2� Position the unit inside the display so the antenna connector can extend through the
hole in the left side of the display.
3� Remove the backing from the fastener strips on the unit, and then firmly press the unit
against the interior, sticking the fastener's adhesive to the sheet metal.
