Section 6: Scoreboard Options
6.1 Horns
Daktronics Tuff Sport scoreboards are equipped with a 120 VAC vibrating horn mounted
behind the scoreboard face. The horn sounds automatically when the period clock counts
down to zero, or when manually triggered by the operator using the control console.
Installation of an optional 12 VDC horn is detailed in Drawing A-148960 in Appendix C.
Louder trumpet horns are also available. Contact Daktronics for information and pricing.
Adjusting Horn Volume
CAUTION: The scoreboard horn is a 120 VAC device. Turn off the power to the scoreboard
before adjusting the horn.
The volume for the electronic, buzzer-type horn is set at its maximum level at the factory. If
the horn is too loud, reduce its volume by adjusting the setscrew mounted in the front of the
horn. A plastic tip on the screw touches the horn's diaphragm, reducing the volume. Turn the
screw clockwise and test the volume by operating the horn from the scoreboard control
console. Continue adjusting and testing until the desired volume level is obtained.
Note that with the noise of spectators, the horn will not seem as loud as when it is being
tested in an empty area, so be sure to set the volume according to the acoustics of the facility.
6.2 Radio Control
Radio control is an option for Daktronics Tuff Sport scoreboards. The system provides
scoreboard control via a 2.4 GHz, extra-high frequency FM signal.
The radio transmitter and receiver are not standard equipment. This setup requires a control
console equipped with a radio transmitter as well as a radio receiver plugged into the
driver/power enclosure and mounted internally to the front panel of the scoreboard.
For additional information about this option, contact a Daktronics representative; for
complete information on setting up radio communication control, refer to the Gen V Radio
Installation Manual (ED-13831) or the Gen VI Radio Installation Manual (DD2362277),
both available online at

6.3 Visual Horn Indicator (VHI)
In addition to the horn, Daktronics offers a visual horn indicator (VHI) that lights up when
the buzzer sounds. To install a VHI, users must tap into the existing horn wiring to provide
power and signal. For more information about installing the VHI option, including details on
the inputs, outputs, and switches of a shot clock relay board that controls when the VHI
should be turned on, refer to the VHI (ED-13397) or BB-2133 (ED-13806) Installation
Instructions, both available online at
