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-HDSW 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-
HDSW 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-HDSW unit.

Multiple KD-HDSW Unit Configurations
Up to 99 individually addressable units can be installed. KD-HDSW switchers allow you to assign
a two-digit address to each unit or each of the selectable inputs. This capability can be configured
via IR or the RS-232 port.

With power enabled on the unit, press the “Power On” button. The “Input Select” LED
lights will begin to blink, indicating that the KD-HDSW unit is ready to receive the address
information.
»
Press the first digit (0 – 9) of the two-digit address. Once this first digit has been received
“Input Select 1” LED will blink.
»
Press the second digit (0 – 9) of the two-digit address. Once this second digit has been
