Conduit
Daktronics does not provide conduit. Separate conduit must be used to route:
• Power
• Signal IN wires to the signal termination enclosure (when applicable)
• Signal OUT wires (if not using the provided interconnect cable)
For power, displays have either a J-box or a 3/4" conduit access hole located in the lower
right on the rear of the display. For signal, displays have signal input quick connects or
etched drilling guides for conduit.
Overview of Power/Signal Connection
Power to the display is terminated externally in most cases. Power Connection (p�6)
shows external wiring examples.
Possible methods for signal termination are shown in the various communication
manuals.
1� Power is routed to the display through a fused disconnect switch capable of opening
all ungrounded power conductors. Install the disconnect within the line of sight of
any personnel performing maintenance on the display, unless it can be locked in the
open position.
2� Route power conductors from the disconnect to the display through conduit
following local code specications.
3� Terminate display power either to the J-box or internally at the power termination
panel.
4� Connect the grounding conductor to the grounding lug on the rear of the display.
5� Route signal cable to the signal termination enclosure. Ground the enclosure to an
isolated earth-ground connector (when required).
6� Route signal into the enclosure through conduit. The knockouts on the enclosure
require the use of 3/4" conduit.
7� Route signal quick-connect cables from the enclosure to the display either through
conduit or through the display pole if power is not also routed in the display pole.
Note: Quick-connect cables MUST be secured to protect them from weather or
vandalism.
Earth Ground Installation
To connect the Daktronics GT6x Small
Matrix display to an earth-ground
electrode, follow these steps:

Grounding
All components of a display system—including but not limited to displays, control
equipment, and connected peripheral equipment—must be electrically grounded.
Only qualied individuals may perform electrical work, including verication of ground
resistance. Daktronics is not responsible for improper grounding or damage incurred as a
result of improper grounding.
Grounding methods must meet the provisions of all applicable local and national codes.
Inspect and verify all grounding methods meet the provisions of all applicable local and
national codes.
Proper grounding is necessary for reliable equipment operation and general electrical
safety. Failure to properly ground the display system may void the warranty, disrupt
operation, damage equipment, and cause bodily harm or death.
Power Connection
Power is most often terminated to the J-box on displays. However, larger displays require
power to be terminated internally in the Power Termination Panel.
Displays With an External Power Termination J-box
To terminate hot, neutral, and ground wires at the
J-box, follow these steps:
1� Route the power cable through conduit to
the rear of the display and into the power
termination J-box [the J-box contains 3/4"
threaded conduit tting(s)].
Note: The J-box contains two or three wires
plus a ground coming from the power
termination panel inside the display.
2� Inside the J-box, connect the power wires to
the wires coming from the display interior using
wire nuts. Refer to Figure 4 for 120 VAC and
Figure 5 for 120/240 VAC.

Communication Installation
This section explains the network settings of displays and gives guidance for integrating
a display with a customer’s network. It also provides basic information about available
standard communication options.
Daktronics is not responsible for setting up a customer’s network system neither a Local
Area Network (LAN) nor a Wide Area Network (WAN).
Keep the following points in mind when installing network and communication:
• Complete all network and communication installation prior to turning on the display.
• Have a laptop with internet access on-site.
• Work with a customer’s IT professional for network integration (preferred).
Network Connection
GT6x Small Matrix displays use Dynamic Host Conguration Protocol (DHCP) by default,
allowing the customer’s network to congure the display and eliminating manual
conguration of the player.
When the display is connected to a network that supports DHCP, a default DHCP name
similar to “DMP8.xx.xxxx” or “DMP5.xx.xxxx”, where “xxxx” represents a unique identier for
the display, is shown in the display boot sequence.
Ports 4500-4525 must be open for communication on the switcher or router.

2� Mix a mild, non-abrasive, non-petroleum-based detergent and cold water. Use one
ounce of detergent to one gallon of cold water.
3� Saturate a light/medium duty cleaning brush with the soapy water.
4� Use horizontal brush strokes to loosen and remove dirt and grime, washing the display
from top to bottom. Use light pressure so as not to damage the LEDs. Clean only an
area that is safely within reach from a lift or stage, and then move on to the next
section of modules.
5� Rinse the display face with generous amounts of cold water under low pressure. A
spot-free rinse agent can be used to reduce water spots.
6� Use soft, dry terry cloth to dry and remove any excess water. Take care not to
damage LEDs by catching the cloth on them.
