857 CONNECTIONS
Power: Connect a 12 VDC 200 mA to 1A power supply to the power jack.
2.1mm + Tip – sleeve. The red LED will be illuminated when powered. This
will power all of the IR components connected to the system. Depending on
the type of components and the number of components will determine how
much current the power supply will need to provide.
Status Power: 12VDC 200mA 2.1mm + tip –sleeve. Connecting a power sup-
ply to this connection will power the status connection. The green LED will
be illuminated when powered. This can be from a 12 volt trigger output or
from a wall type power supply plugged into a switched outlet of a stereo
receiver. If you are using products like the 858 that have a status indicator,
simply plug a 12 VDC power supply into the switched outlet and when the
receiver is turned on the status LED will be illuminated.
