3.2 Signal Termination Enclosures
In each communication method, the final connection will be from a weather resistant
enclosure to the display. For signal termination to the enclosure, see the manual
included in the box with the enclosure.
Note the following information when mounting the enclosure:
1.
Be sure to mount the enclosure with the cables exiting from the bottom to
prevent water from entering into the enclosure.
2. A quick connect cable will be connected to the signal termination enclosure
and will terminate to the back of the primary display. The length of the
cable is 25 feet.
3. The quick connect cable can be run from the enclosure through 2" conduit
or through the display pole to the sign, but it is not required. The cable is
weather and sunlight resistant.
Note: Daktronics engineers strongly recommend that the quick connect cable be
secured to protect it from weather or vandalism.
4. Earth ground enclosures that use wire signal cable – the resistance to
ground of 10 ohms or less is required (a grounding electrode conductor is
attached to the enclosure to make the necessary earth ground connection).

Follow these steps for wiring
between the sections after the
sections are firmly attached
to each other and securely
mounted.
1. A power
interconnect cable
connects from the Z-
filter in the top
section to the power
termination panel in
the bottom section.
This cable is already
plugged into the Z-
filter in the top
