The handset enclosure consists of a small weatherproof box which houses the handset and a
junction box (refer to Figure 2). A 25-foot signal cable is provided to connect the handset

the handset as follows: Note: This signal cable has a typical 25 foot length and a maximum
50 foot length. Cable length beyond this is not recommended.
1. Mount the handset enclosure at the base of the display in a position where it will be
possible to see the display when using the handset. The handset has a six-foot cable that
plugs into the j-box.
2. Run the signal cable (Belden 8771, Daktronics part number W-1214) through1/2” conduit
from the handset enclosure into the display, and route to the display controller enclosure.
Knockouts are provided in both the handset enclosure and the display.
3. Remove the cover from the handset j-box and route the cable into the j-box. Connect the
three wires terminated with spade lugs to the terminal block mounted on the j-box cover.
Connect CLR (SIG) to WHT, BLK, and RED respectively, already connected to the
terminal block. Cut the shield back and leave it unterminated. Replace the cover and plug
in the handset.
4. Remove the cover from the controller enclosure and connect the control cable to TB3 on
the controller. Connect CLR to position 1, RED to position 6, and BLK to position 5.
