Remotely Cycle Power
Daktronics DXB 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

reading the relay function table:

TRON (325-8766) for assistance. 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.
