1.2 Display Identication
This section provides information that is helpful in understanding a Daktronics digital billboard
display label. Refer to Figure 1 while reading the table below.
1.3 Terms Used in this Manual
DMP-8065: digital billboard control card that sends content to the display. The DMP regulates
display content and content hold times.
Lanyard Attachment Ring: a ring found on the back of each module and on the display doors
that attaches to a lanyard and prevents the module or door from falling.
Latch Release: a device that holds the module firmly to the display frame. There are two per
module, one on the top and one on the bottom.
Light Emitting Diode (LED): low-energy, high-intensity lighting unit.
Line Filter: a device that alternates electromagnetic interference that might disrupt local
communication channels and internal equipment operation.
Louver: a black plastic shade positioned horizontally above each pixel row. Louvers increase
display contrast.
Module: consists of a display board with LEDs, a driver board or logic card, housing, a module
latch assembly, and a louver. Each module is individually removable from either the front or
back of the display. Module part numbers vary by pixel pitch.

ProLink Router (PLR): the PLR takes data in from the DMP and then routes that data to other
areas in the sign. There is typically one PLR per display section.
Power Supply: a device that converts AC line voltage from the panel board to low DC voltage for
driver boards. One power supply powers multiple modules.
Serial Advanced Technology Attachment (SATA) Cable: allows high-speed signal transfer from
device to device. In digital billboards, they run signal from module to module.
Termination Block: an electrical connection point, usually used to connect internal power or
signal wires of the same type coming into the display from an external source.
1.4 Spare Parts Box
Every Daktronics digital billboard is shipped with a spare parts box that includes commonly
replaced components. The table below lists some of the components that may be included in the
spare parts box. Refer to the spare parts inventory list on the top of the display spare parts box
for a list of the parts in your spare parts box. Contact the Account Service Manager (ASM) to
order additional spare parts.
1.5 Field Replaceable Units
The table below lists component names and part numbers of components that can be replaced in
the display and the control system. Some of these components may be located in the spare parts
box. Contact the ASM to order components when needed.

Display and Control Overview
Section 2: Display and Control Overview
This section describes generic power and signal paths for Daktronics digital billboards. Refer to display
specific signal and riser drawings for component locations on your display.
2.1 Internal Display Control System Flow Overview
Figure 2 shows the location of the ISP enclosure and the DMP-8065. The control system bay or
components may vary by display. Refer to project specific drawings for your display control
location, signal path, and power path.

2.2 Display Power Overview
The power system for the 4203 series is significantly different than any previous series of
Daktronics digital billboards. Each 65 Watt power supply powers two modules. In most cases, the
module power path follows the signal path. Figure 3 shows a basic overview of what the power
system looks like in an individual display section. Power to the display section enters into the
termination panel and is redistributed to the power supplies. Refer to the layout drawing for
display specific power distribution.

Display and Control Overview
2.3 Display Signal Overview
This section provides generic signal path illustrations for even module tall sections, Figure 4, and
odd module tall sections, Figure 5.
Signal is sent from the DMP-8065 and is sent to the ProLink Router (PLR) in the display section.
The PLR then sends the signal to the first module in the section. From that module, the signal is
then sent to the other modules in the section. The PLR not only sends signal to the first module in
the chain but also receives signal from the last module in the chain and creates a redundant signal
path.
