" bolts to attach the modules to the struts. Mount the lowest module
first, and then mount any additional modules, working upward.
Beam Mounting, Outdoors, Single Display
Use this method when the scoreboard is mounted individually, not within a whole
display system. Refer to Drawings
A-175677, A-175696 , and A-175784 for further
information.
1. Attach the mounting brackets to the rear of the display using the included

" hardware. Holes are provided in the mounting brackets and in the back
of the display.
2. Position the display against the beams and secure to the beam with the

bolts, washers, and nuts provided. The square nuts go inside the bracket,
and the hex nuts and washers are used inside the rear angle at the back of
the beam. Use a
3

" socket to tighten.
Note: Overtightening can deform the brackets and angles!
Beam Mounting, Outdoors, Multiple Displays
Daktronics LED tennis scoreboards are most frequently displayed as freestanding
units, mounted on steel beams. Because every display is different in terms of module
configuration, scoreboard options and environment, every installation will be
unique. Such beam-mounted installations require that a qualified engineer provide
specifications for both the reinforced concrete footings and the steel support beams.
Two beams are required for each scoreboard or module combination, and they must
be set 4'6" apart, center-to-center. The typical vertical installation is shown in
Drawing A-134556, which also specifies the overall dimensions and space
requirements for the scoreboard modules.
Once the support beams have been installed, the scoreboard-mounting procedure
(located on the following page) is typically a six-step process. Refer to
Drawings
A-134762 and A-134759.
Note: Overtightening can deform the brackets and angles!
If it is not already attached, set the caption module atop the digit module, and secure
the two together with screws. The fasteners are inserted up through the top of the
digit module and threaded into the captivated nuts in the bottom of the caption
module. (The caption module is attached directly to its adjoining digit module and
does not accept beam-mounting brackets.)
If an optional ad or ID panel is used, attach mounting brackets to the top and bottom
of the rear of the panel.
1. Secure the mounting brackets of the ad panel module to the beams with
bolts, washers and nuts.
