Whenever possible, Daktronics mounts the data distributor enclosure to the rear of the display or
display section. However, structural variables sometimes require the shipping the data distributor
independently and mounting it on site, either to the display itself or to a nearby structure.
Drawing A-118499 in Appendix A illustrates a data distributor mounted to the back of a display
section. Drawing A-119584 in Appendix A shows a data distributor mounted to a support structure.
Attached to the rear of the data distributor are two mounting plates – one on the top and one on the
bottom. The data distributor can mount by running bolts through the holes in these mounting plates.
Refer to Drawing A-117702 in Appendix A for a detailed drawing of the mounting plates on a data
distributor.
In displays with a data distributor (refer to Data Distributor Definitions in Section 1.3 for data
distributor description) data travels to column directors within the display through RJ45 cables. Be
sure not to mount the data distributor enclosure so far away from the display that the RJ45 cables
cannot reach between the two. Daktronics usually cuts RJ45 cables to length.
Signal and power cable into the data distributor enclosure should both be run through separate, rigid,
metal conduit, as opposed to flexible conduit (metal or PVC). Section 3 addresses power and signal
connection.

Submit any new plans for filtering air in an enclosed display to Daktronics engineering staff for
evaluation and approval or the warranty will be null and void. If modifying the Daktronics air
filtration system in any way, Daktronics engineering staff must first approve these changes.
In enclosed displays, 12 square inches of unobstructed opening per module is required to ensure
adequate display cooling. Make allowances to compensate for the percentage of screen in the material
covering the openings in the enclosed structure. If forcing air into the enclosed area, the fans must
