border shrouding and back sheets. If ANY modifications are made to the weather
tightness of the display, detailed drawings of the changes MUST be submitted to our
engineering staff for evaluation and approval or the warranty will be null and void.

Daktronics is not responsible for the integrity of the mounting structure or any
mounting hardware not provided by Daktronics. It is the customers responsibility to
ensure that the structure and any additional hardware have been approved by a
qualified structural engineer.

2.1 Mounting Kit

An optional mounting kit is available when ordering a display. The mounting kit includes the
hardware to either mount the display on a pole or to a wall. Please specify the desired mounting
method when ordering a mounting kit. When using a Daktronics mounting kit, refer to the
instructions in Section 2.2.

2.2 Cabinet Display Mounting

L Note: There are end caps located at either end of the display for maintenance access. Care

must be taken when mounting the display not to obstruct the end caps. The following two example
mounting methods, wall mount and pole mount, take this into consideration.

2.2.1 Wall Mount

Reference Drawings: Wall Mount ...................... Drawing A-79703

L Note: Because each site differs, the Daktronics wall mount kit is not a complete

installation kit. It is the customer’s responsibility to determine the proper wall mounting
method and location.

Refer to Drawing A-79703 for a suggested mounting method. The number of wall
brackets needed and the wall structure must be reviewed by a qualified structural engineer
and meet all local codes.

Power/Signal Termination Panel ............. Drawing A-88427

Overall Dimensions; G-1000 ................ Drawing A-88154

Daktronics does not include the conduit. Knockouts will be provided. Separate conduit must
be used to route:

C power
C signal IN wires
C signal OUT wires (if signal is required for another display).

The conduit holes are located at the bottom right (rear view) of the back of the display.

To access the knockouts, remove the right end cap (front view) on the bottom line and slide the
face panel out until the left module is cleared. Refer to Drawing A-88154 (Section 1) and Section

4.3 to remove the module.

Punch or drill out the desired knockouts. Note: Be careful that none of the components are damaged.
Attach the conduit and route the power and signal cables. Refer to Drawing A-88427 for the signal
and power termination panel.

For displays with more than one face, signal and temperature sensor wiring between the displays can
be routed through the same conduit.

3.2 Grounding

The display must be connected to earth-ground. Proper grounding is necessary for reliable
equipment operation. It also serves to provide protection to the equipment against damaging
electrical disturbances and lightning. If the following grounding methods are not adhered to,

the warranty will be void.

˜ Displays MUST be grounded according to the provisions outlined in Article 250 of the

National Electrical Code.˜

The support structure for the display cannot be used as grounding. The support is generally
embedded in concrete, and if in earth, the support is either primed or it corrodes, making it a poor
ground. Use one ground rod at each support column.

The National Electrical Code requires the use of a lockable power disconnect near the display.
Provide a lockable disconnect switch (knife switch) at the display location so that all power lines
can be completely disconnected. Use a multi-conductor disconnect so that all the hot and the
neutral lines can be disconnected. This is important in protecting the display against lightning.

There are two considerations for power installation, New Power and Existing Power Installation.
These two power installations differ slightly, as described in the following paragraphs.

Electrical
Installation 3-1

3.2.1 New Power Installation

The power cable must contain a separate earth-ground conductor. When a separate
ground conductor is used, do not connect neutral to ground at either the disconnect or the
display. To do so violates electrical codes and voids the warranty (refer to Figure 1).

Figure 1: New Power Installation

3.2.2 Existing Power Installation With No Earth Ground Conductor

When a separate ground conductor is not available, connect the neutral to the earth-ground
at the disconnect, never at the display (refer to Figure 2).

Figure 2: Existing Power Installation

Electrical

Installation3-2

3.3 Control Cable Requirements

3.3.1 RS/232

This cable is a 2-conductor shielded cable used to transmit a RS/232 signal (Daktronics
part number W-1117). This shielded cable should not be subjected to mechanical flexing
after installation. This cable is not for direct burial and should be routed in a dedicated,
grounded metallic conduit at the base of the display structure. This cable has a maximum
length of 25 feet.

3.3.2 RS/422

This cable is a 6-conductor unshielded cable used to transmit a RS/422 signal (Daktronics
part number W-1210). This unshielded cable consists of paired wires. They should not be
subjected to mechanical flexing after installation. This cable is not for direct burial and
should have one of the following routings:

1. In dedicated metallic conduit

2. In plastic conduit away from interference signals

3. Inside buildings - if cable is not in conduit, keep away from interference signals.

L With interference signals, such as power conductors, intercom, etc., a two-

foot separation is typically required.

3.3.3 Modem

The modem option will use standard telephone cable routed through conduit. The local
telephone company will need to assist in this installation.

Ask the telephone company which colors are used by the TIP, and the RING for signal
hook up. U Note: The telephone lines must be dedicated lines and not run through a
switch board/communications system.

3.4 Signal Termination From Computer To Display

3.4.1 RS/232

Reference Drawings: Signal/Power Termination Panel ..... Drawing A-88427

System Riser Diagram (232) ........ Drawing A-96058

One end of the signal cable should be terminated to the 10 position terminal block in the display
labeled “DATA IN” (TB42). Drawing A-88427 is an example of the termination panels. The
other end is terminated at the J-box at the display structure. The laptop PC connects to the

must be removed.

4.6.3 Controller Address and Test Mode

Before a display can be run in a sign network, it must have an
“address.” The display address can be set by the use of “DIP”
switches located on a PC board known as the MDC. The MDC
is the circuit card mounted in the lower right corner of the
controller board (as seen in Figure 11).

Locate the DIP switches on the MDC. They should be on the
bottom end of the card (if it is oriented as shown in Figure 11).
Refer to Figure 12 for a picture of the DIP switches.

When replacing a controller board, be sure to set the DIP
switches in the same address configuration as the defective
controller.

footings, structural tie points and ground rods. Fasteners should be checked and tightened or
replaced as required.

At least once a year, check the inside of the display for sign of water intrusion, i.e. water stain
marks. Water can enter a display where weather stripping has come loose or deteriorated, where
fasteners may have come loose allowing gaps in the panels, or where moisture may be entering
around hardware which is in the top of the display. Check the electronic components for signs
of corrosion.

4.14 Unit Exchange/Replacement Procedure

Daktronics unique exchange program was designed with the client’s needs in mind. This is the
quickest and most economical way available for product repair. If a component has failed,
Daktronics will send the customer a replacement. The customer, in turn, sends the failed
components to Daktronics. This not only saves money but also decreases the amount of time
that the display is inoperable. Daktronics offers a repair and return on a timely basis, but in
urgent situations, every attempt is made to ship by the fastest transit method available.

1. Packaging for Return: Package and pad the item well so that it will not be damaged in

shipment. Electronic components such as printed circuit boards should either be
installed in an enclosure or should be put in an anti-static bag before boxing.

Please enclose your name and address with all symptoms listed as best you can describe
them.

2. LED Display Board or Driver Board Packaging Instructions: LED modules should

be placed in a static-free enclosure for return shipping. An anti-static convoluted foam
packing is available from Daktronics, part number PK-1135 for your use if needed. The
shipping box (Daktronics part number PK-1006) should be used in conjunction with the
foam.

3. Where to Send: To return parts for service, contact your local representative prior to

shipment to acquire a Return Material Authorization Number (RMA#). This will speed
up the repair of your unit.

For return of defective items under the exchange program, please utilize the UPS Blue
Return Tags found in the package containing the exchange unit sent from Daktronics.
This will speed up the transaction and will also avoid any confusion when the part is

returned to Daktronics. @ The defective item must be returned within 15 days of
receiving a replacement part. Using the UPS Blue Return Tag immediately will

eliminate the possibility of late charges being assessed against your account.
