Controller Diagnostics
The Galaxy
®
Large Matrix GS6 controller is located in
the lower-left portion of the display in an environmental
enclosure. The controller receives incoming signal from
the control computer and routes that signal to the
display. The controller has three LEDs on it that can be
useful when troubleshooting a communication issue.
shows those LEDs.
PLR Diagnostics
The ProLink Router (PLR), receives signal from the display
player, which transfers it on to the modules through SATA
cables. Galaxy
®
Large Matrix GS6 series displays are
equipped with a redundant signal path, meaning two
SATA cables are connected to each module. If one of
the two SATA cables fail, the module continues to receive
data from the other SATA cable and the display continues
functioning normally.
PLR Self-Test
When put into self-test mode, the PLR tests for correct
operation and displays pass/fail status on the 7-segment
display.
To put the PLR into self-test mode, loop a SATA cable
between ports A and B. Then take a fiber cable and
connect the fiber ports together. Refer to
the cables are connected, cycle power to the PLR and it
will boot-up in self-test mode. Following is a table of a few
possible messages. Contact Daktronics Technical Support
for additional information or questions.
