Remotely Cycle Power
Each Daktronics 5000 series display ships with
a SmartLink
TM
. The SmartLink
TM
has four different
relays that the Daktronics help desk uses to
remotely cycle power to some control and display
components. Refer to Figure 12 while reading the
relay function table below:
Relay Component
R1 ISP Enclosure
R2 DMP-8065
R3 Display
R4 Auxiliary Power
If remote troubleshooting is desired, call Daktronics help desk at 1-877-DAK-HELP and
they can assist. Do not press the buttons in the SmartLink
TM
to cycle power to the
components because it can take as long as an hour to reset the relays.
