The installer must ensure the
installation adequately meets local
codes and standards, including
safe, adequate mounting hardware
and procedures.
Note: To maintain the structural
integrity of the display cabinet,
a 90-degree angle between the
cabinet and the lifting method must be maintained.
1. Lift the display into position on the support structure following the
guidelines in Figure 2.
Be sure the mounting location leaves adequate space to pivot the
door open, as shown in Figure 9.
Do not attempt to permanently support the display by the eyebolts.

Section 3: Power Installation
3.1 Installation Guidelines
DO:
• Route power to the display through a fused disconnect switch
• Route power conductors through conduit according to local codes
• Install an earth-ground electrode for each display face – if resistance to ground is greater than 10 ohms,
install additional grounding electrodes
• Follow local and national electrical codes
• Provide a main power disconnect for the displays
DON’T:
• Connect the display to any voltage other than that listed on the product label
• Share a circuit or neutral with any other electrical devices such as light ballasts, parking lights, etc.
• Connect the neutral to the ground at the disconnect or the display
• Use the display support structure as an earth-ground electrode
3.2 Conduit
Daktronics does not include the 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)
The power J-box is provided with 3/4" threaded holes for use with 3/4" conduit. Unthreaded 1/2" knockout
holes are provided in the signal enclosures used with the display. If not using the provided enclosures, use
the knockout/drill holes provided in the display cabinet.
3.3 Power Requirements
Important Note:
• Daktronics recommends that a separate circuit be run to the electronic display(s) to isolate it and
prevent any issues that could be caused by line voltage fluctuations or high frequency noise on the
power line caused by other types of equipment. A separate circuit also makes display maintenance and
troubleshooting easier. Daktronics assumes no liability for any issues caused by line voltage fluctuations
or other improper power conditions if these recommendations are not followed.
• Size conductors of circuits that deliver power to a Daktronics display according to local and national
electrical codes so that the power distribution system delivers full-load power to the display while
maintaining a voltage within five percent (5%) of the nominal voltage.
Power Installation 5
Page 10
• Displays use single-phase power. Proper power installation is imperative for display operation.
Main Disconnect
Daktronics requires using a power disconnect switch with the display. Use a disconnect so that all
ungrounded conductors can be disconnected near the point of power connection.
The disconnecting means must be located either in a direct line of sight from the display or can be locked
in the open position. This ensures that power will not be reconnected while service personnel work on the
display.
3.4 Grounding
Install this sign according national and applicable local codes. This includes proper grounding and bonding
of the sign.
Installation with Ground and Neutral
Conductors Provided
• These displays are installed
with ground and neutral
conductors provided. The
power cable must contain
an isolated earth-ground
conductor.
• Do not connect neutral to
ground at the disconnect or
at the display. This violates
electrical codes and voids the
warranty.

ADDRESS
UPPER

The rotary switches set the hardware address of the controller. Each Primary
display in a network needs a unique address, as shown in Figure 17. Each
controller in a network also needs a unique address.
Set the switches by rotating them counterclockwise until the arrow points to
the desired number. The display’s power must be turned off and then turned
back on to activate a change in the address.
Note: Setting both rotary switches to address 0 will activate a Test Mode.

Section 9: Daktronics Exchange and Repair &
Return Programs
9.1 Exchange Program
The Daktronics Exchange Program is a quick, economical service for replacing key components in need
of repair. If a component fails, Daktronics sends a replacement part to the customer who, in turn, returns
the failed component to Daktronics. This not only saves money but also decreases equipment downtime.
Customers who follow the program guidelines explained below will receive this service.
Before Contacting Daktronics
Fill in these numbers before calling Customer Service:
Display Serial Number:________________________________________
Display Model Number:_______________________________________
Date Installed:________________________________________________
Location of Sign:______________________________________________
Daktronics Customer ID Number:_______________________________
To participate in the Exchange Program, follow these steps.
1. Call Daktronics Customer Service: 888-DAK-SIGN (888-325-7446)
2. When the new exchange part is received, mail the old part to Daktronics.
If the replacement part fixes the problem, send in the failed part within 3 weeks of the ship date.
a. Package the old part in the same shipping materials in which the replacement part arrived.
b. Fill out and attach the enclosed UPS shipping document.
c. Ship the part to Daktronics.
3. A charge will be made for the replacement part immediately, unless a qualifying service agreement is
in place.
In most circumstances, the replacement part will be invoiced at the time it is shipped. If the failed
part or replacement part is not returned to Daktronics within 3 weeks of the ship date, it is assumed
that the customer is purchasing the replacement part and will be invoiced for the value of the new
sale part.
If the part or parts are returned within 2 weeks of the second invoice date, Daktronics will credit the
customer for the amount of the second invoice. If after 2 weeks Daktronics has still not received the
parts back, the customer must pay the second invoice and will not be credited for the return of the
failed part.
Daktronics reserves the right to refuse parts that have been damaged due to acts of nature or causes
other than normal wear and tear.

Glossary:
3220: The series name of the display, for example Galaxy AF-3220
Controller: The “brains” of the display. The controller receives signal communication from the computer and sends
the appropriate information to the modules. Messages and schedules may also be stored on the controller.
Display Address: An identification number assigned to each display of a network. The control software uses the
address to locate and communicate with each display. Displays that are on the same network must have different
addresses.
Driver/LED Board: The components of a module. This board is responsible for the on/off and intensity levels of the
LEDs.
Galaxy®: The name given to Daktronics LED matrix displays that can be monochrome, tri-color, or RGB.
Light Emitting Diode (LED): A low energy, high intensity lighting unit.
Mirror: The second display in a two-face configuration. The mirror display does not have a controller so it displays
an exact copy of the information on the primary display. All signal information to the mirror is received through an
interconnect cable from the primary display.
Module: The board containing the LEDs and driver. Galaxy®AF-3220 34 mm modules are 8 pixels high by 16 pixels
wide. Each is individually removable from the front panel of the display.
Network: Multiple displays connected to each other. As many as 240 primary displays can exist on one network.
Pixel: A cluster of LEDs acting as one unit on the module. The number of LEDs in a pixel will depend on display
application.
Primary: A single-face unit or the first display in a primary-mirror (2V) configuration. The communication signal,
light sensor and temperature sensor will be connected to this display. An interconnect cable transfers information
from the primary display to the mirror display so that it shows exactly the same information.
Venus® 1500 software: Name of Daktronics software that is used on the control computer to communicate with
these displays. This software can create messages and send them to the displays, schedule messages, and perform
diagnostics. The Venus® 1500 software manual is included on the installation disk.
