Remotely Cycle Power
Daktronics DB series displays ship with an integrated
SmartLink
TM
for remote power control of display
components. The SmartLink
TM
has four relays for
independent control of various components as shown
in the relay table. The DMP-8000 monitors equipment on
the network and attempts recovery via communication
between it and the SmartLink
TM
. Refer to
while
reading the relay function table:

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.
