If you wish to carry remotes that have the same codes from room-to-room, use a Dedicated IR Bus
System as shown in Fig. 4.
5. A 490-30 "Micro Link" IR Receiver plugs into the 789-44 for local control of the source equipment (i.e.
equipment behind closed doors, etc.).
6. A "STATUS" system is included. This permits the power "ON/OFF" status of the A/V receiver or
amplifier system to be visible in each of the remote rooms. It also permits the power management
capability of the Smart Pad
3
to operate.
7. The "STATUS" indicator LEDs on the 780-80 "J" Box IR Receiver, the two MIRV1 Volume Controls
and the Smart Pad
3
, are powered by a 786-00 Power Supply plugged into a "SWITCHED" AC outlet
on the A/V receiver or amplifier system. When the switched outlet is "ON", +12 Volts from the
786-00 passes through one of the 4 bus-conductors (STATUS line) to the LED indicators.
NOTE: A resistor can be placed in series with the STATUS terminal at each IR receiver (IR receivers
only, if so equipped) for adjustment of the brightness of the Status LED. See the specific installation
instructions for the IR receiver for details.
NOTE:
When connecting system devices, be sure to carefully match up the terminals according to
their markings as follows:
IR IN (IR), STATUS (ST), GND (G) and +12VDC (V).
Power Supply Considerations
Up to 3 RAT1's plus associated MIRV1's and IR components can be used with one 782-00 Power Supply.
(e.g. 9 RAT1's with associated components would require 3 of the 782-00 Power Supplies). Typical power
supply connections are shown in Figs. 3, 4 and 6.
