2 Display and Control Overview
This section describes generic power and signal paths for Daktronics digital billboards.
Refer to display-specic signal and riser drawings for component locations on your
display.
Display Control System Flow Overview
Figure 5 shows the location of the
ISP enclosure and the SmartLinkTM
power control device. The control
system bay or components may
vary slightly by display. Refer
to project-specic drawings for
display control location, signal
path, and power path.
Display Power
Overview
Each 400W power supply powers 10
modules in DB-65 series billboards.
Power to the display section enters into the termination panel and is redistributed to the
power supplies. Refer to the layout drawing for display-specic power distribution.
Display Signal Overview
Signal is sent from the DMP-8000 to the VIP-5160. The VIP-5160 sends signal to the PLR,
which sends the signal to the rst module in the section. From that module, the signal is
sent to the other modules in the section. The PLR not only sends signal to the rst module
in the chain but also receives signal from the last module in the chain and creates a
redundant signal path.
See Block Diagrams DWG-04269758, DWG-04269759, and DWG-04269760 in Section A:
Reference Documents (p�25) for signal routing details.

Issue Issue Image Troubleshooting Steps
Blank display
section
1. If applicable, verify the ber interconnects
are installed.
2. On displays with multiple sections or power
entrances, verify the power interconnect
cables between the display sections are
connected.
3. Check the modules at the beginning and
end of the affected area. This issue can
be caused by disconnected or bad SATA
cables on both of those modules. If the
module power indicator is on, there is most
likely a SATA cable issue. If the module
power indicator light is off, there is most
likely a module issue.
4. Measure site power and verify it meets
the requirements listed on the system
riser. If this issue appears when there is
white or light content, it is possible there
is insufcient power to the display. If this
is the case, work with an electrician to
establish the correct site power.
5. Verify the PLR has power and is
functioning. Disconnect and reconnect
power to the PLR.
6. Verify there is power to that display section
by checking module status indicators on
multiple modules. If there is no power,
check the breakers on that sections term
panel.
7. Check that the contactors in each display
section are closed which means that
section should be receiving power.
1 module out
1. Ensure the SATA and power cables to the
module are connected and secure.
2. A SATA cable may be damaged, replace
both SATA cables to the module to see if
this addresses the issue.
3. It is likely a bad module. Swap the module
with a replacement module and verify
that the new module functions correctly.
Multiple modules
out
1. Check module output with a multimeter
to verify there is output from the 12VDC
supply. If there is no output, and there is
power connected to the power supply,
replace the power supply.
2. If there is power to the power supply and
the modules, check the SATA cables to
the modules. It is possible the SATA cables
at the beginning and end of the affected
modules are disconnected or bad.

Issue Issue Image Troubleshooting Steps
3 or more
modules out
in a line within
the same PLR
section
1. Check the modules at the beginning and
end of the affected area. This issue can
be caused by disconnected or bad SATA
cables on both of those modules. If the
module power indicator is on, there is most
likely a SATA cable issue. If the module
power indicator light is off, check the
power supplies for the modules at each
end of the issue are on. If not power or
signal, it is most likely a module issue.
2. Measure the site power to verify it meets
Daktronics requirements. If this issue is only
seen with white or light-colored content,
there is most likely a power issue. If there is
insufcient power, work with an electrician
to establish proper site power.

Test and Replace a ProLink Router
A ProLink Router (PLR) sends the signal from the DMP-8000
to the modules via SATA cables.

Test a PLR
Before replacing a PLR, it may be benecial to perform a
self-test. To perform this test:
1� Connect a duplex ber cable from Fiber Port A to
Fiber Port B. Refer to Figure 24.
2� Connect a working SATA cable from SATA Port A to
SATA Port B.
3� Connect the power cable to the PLR. This will
start the PLR self-test.
4� Wait for the test to complete. This may take up
to 90 seconds. If the PLR has successfully sends
and receives data through each of the ports,
the letters P.A.S will appear on the Seven
Segment Display. If the letters E.r.r appear, the
Seven Segment Display will show the port
numbers with issues. Refer to the ProLink Router
6050 Manual in Section A: Reference
Documents (p�25) for a full list of error codes.
The PLR outputs test patterns in a specic order
starting with Red, Green, Blue, and White. The PLR
sends out these patterns with full redundancy (out
both port A & B at the same time). If all of the modules change colors, it shows they all
work and that visually the display is ne, but there
could still be a signal failure that will not show
up visually because of redundancy. The Amber/
Yellow and Magenta test patterns provide a way
to nd the normally non-visual breaks.
After it shows the White test pattern, the PLR shows
a Yellow pattern, but it only sends the that pattern
out on port A (no redundancy), any modules that
receive that command will turn Yellow. However, if
there is a signal break, the modules will not receive
the command to turn Yellow and will remain at
their previous color, which was probably White, as
shown in Figure 25. The modules that turn Yellow
are working correctly. Modules that are not Yellow
indicate where the signal break is. If all of the
modules turn Yellow, it indicates the signal path in
the “A” direction is working 100 percent.
After showing the Yellow pattern, the PLR shows the Magenta pattern, but it only sends
that pattern out on Port B. Any modules that do not receive the magenta command will
remain at their previous color, which is probably Yellow, as shown in Figure 26. Wherever
they do not turn magenta indicates a signal break. If they all turn Magenta it means the
signal path in the “B” direction is 100 percent.
