Serial IR & IR Emitter Control
½
The “Serial IR” port requires the use of a Male 3.5mm Mono cable (not included) with the IR
command signal being carried on the “Tip” of the input inserted into the KD-HDRV unit. The
location of the IR signal may vary by control system used. Please verify the location of the IR
signal with your control system.
½
When using the IR Emitter / IR Extender (sold separately), the
IR Emitter must be mounted over the IR Sensor on the KD-
HDRV unit. It is recommended that the rear IR sensor of the
KD-HDSW unit be utilized for these applications. One end of
the cable is connected to the IR Receiver / Master Controller
/ IR Extender / IR Connecting Block, while the other end is
mounted over the IR Sensor of the KD-HDRV unit.
