Installation and Operation
Before permanently securing the unit for final installation of cabling behind walls or ceilings, test
for proper operation of the unit and the cables in your system. It is recommended that you leave
enough ventilation space to provide sufficient airflow and cooling, especially if you are going to
leave the unit powered at all times.
Pushbutton Control
Your KD-HDRV unit may be controlled via the pushbutton on the front of the unit. Select your
desired input by depressing the “Input Select” button. The front LED indicators (1, 2, 3, 4)
correspond to the input that has been selected.
IR Remote Control
The KD-HDRV can also be operated using the IR remote control provided with your unit. The
KD-HDRV switcher features IR sensors on the front and rear of the unit for reception of the IR
command signals.

Serial IR & IR Emitter Control
½The “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.
½When 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.
RS-232 Commands and Protocol
½KD-HDRV units are compatible with all Control Systems, such as AMX

½Connect your Control System’s Master Controller to the KD-HDRV unit using the RS-232 port.
Follow all instructions provided with your control system.
½RS-232 Protocol:
»Baud Rate = 9600 bits per second
»Data Bits = 8

Multiple KD-HDRV Unit Configurations
Up to 99 individually addressable units can be installed. KD-HDRV 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.
½Addressing Buttons / Units via IR
»With power enabled on the unit, press the “Power On” button. The “Input Select” LED
lights will begin to blink, indicating that the KD-HDRV 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
received “Input Select 1” and “Input Select 2” LED’s will blink.
»Press the Input Select button (Input 1 – Input 4, Up or Down) that you wish to assign the
two-digit address to. Once this is completed, all “Input Select” lights will become solid
indicating that the Input Select button has now been re-addressed.
»Repeat Steps 2 through 4 if you wish to assign an address to additional “Input Select”
buttons or to your entire KD-HDRV unit.
»Press “Power On” button to exit addressing mode when completed.
½Addressing Buttons / Units via RS-232
»See “RS-232 Commands and Protocol” section for RS-232 Addressing Commands
»To address an Input, use “sir_x_x_y” command. To address an entire unit, repeat command
for each Input, Up, and Down
»For address settings, use “gir” RS-232 command to receive a list of address settings
»To delete address settings, issue “dir_y” RS-232 command

EDID Control Settings
At times, your HDMI sources and display may not synchronize properly.
This is when EDID* control should be utilized. KD-HDRV switchers
feature an internal library of default settings that modify KD-HDRV input
port’s EDID to ensure that your HDMI source’s output is compatible with
your display.
Dip Switch Configurations:
Configuration Description
000 Bypass (EDID Information of Display)
001 Video = 1080i, Audio = L/R Stereo
010 Video = 1080i, Audio = All Audio formats including HDMI 1.3a/b
011 Video = 1080p Audio =L/R Stereo
100 Video = 1080p Audio = All Audio formats including HDMI 1.3a/b
All Others Bypass (EDID Information of Display)
*EDID (Extended display identification data) is a data structure provided by a display to describe its
capabilities to a source device.
