½The RS-232, Serial IR, Optical IR Sensor, Operation Mode Switch and Power connections
are located on the right side of the back panel. The Operation Mode switch is used to update
the unit’s firmware which is done using the DB9/RS-232 port. The firmware version as well as
all RS-232 commands is available through the RS-232 command ‘H’. A detailed list of RS-232
commands is available later in this guide.
½If newer firmware is made available, complete

Quick Setup Guide:
1. Begin with the KD-4X4 and all input/output devices turned off and power cables removed.
2. Connect HDMI sources to the appropriate input ports on the KD-4X4.
3. Connect HDMI outputs to the appropriate output device (display, projector, AV Receiver, etc).
4. Connect power to the KD-4X4 as well as to all other input and output devices
and turn them on.
5. Operate the KD-4X4 switcher via front panel buttons, IR Remote, Serial IR or RS-232 control.
Operation:
After performing the setup above, the unit is ready for operation.
There are several options for controlling the unit. Commands can be issued via IR remote control,
RS-232 or by using the front panel buttons. Note that the advanced commands are available only
via the RS-232 protocol.
Settings
The KD-4X4 features a library of 9 internal EDID (Extended Display Identification Data) files, in
addition to allowing any Input source to receive a copy of the EDID information of any selected
Output connected via HDMI. The default EDID setting is “01” – 1080i w/ PCM 2ch Digital Audio.
Changing to EDID settings may be necessary when connecting to or from an AV Receiver, or for
passing 3D content derived from a Cable or Satellite source if the default EDID has problems. They
can also speed up the switching process with cable or satellite sources.
The possible EDID settings can range from ‘01’ to ‘09’. (‘01’ is the default).
01 1080i w/ PCM 2ch Digital Audio 06 3D w/ Dolby Audio
02 1080i w/ HD Audio 07 3D w/ HD Audio
03 1080p w/ PCM 2ch Digital Audio 08 DVI VESA 1280x1024
04 1080p w/ HD Audio 09 DVI VESA 1920x1200
05 3D w/ PCM 2ch Digital Audio
When selecting an EDID from the library (settings 01-09), your source device will “see” the KD-4X4
EDID choice instead of the displays EDID, over riding the displays own EDID information.
If your display is not capable of accepting the video resolution or audio type selected, you may
not see a picture or sound. In this case please choose another more compatible EDID, or use the
default EDID.
EDID settings can only be changed through the RS-232 command protocol. See the RS-232
command section below for a list of EDID commands available.
Remote Control
You may control the KD-4X4 switching commands by using the
supplied IR Remote control. There are 4 groups of controls, one
group for each Output. Each Input can be selected by pressing the
Input numbers 1-4.
IR Extender:
You may want to use an IR extender, such as the KD-IRKIT300:
Front and Rear panel sensors are available for use with the IR
extender. A wired IR serial connector is also provided at the rear of
the unit.
Wired IR Extender KD-IRB3099 Unit included in the KD-IRKIT300
uses a 3.5mm male-to-male Mono cable.
RS-232 Commands:
The KD-4X4 provides access to all functions when used with an RS-232 control system.
The connection protocol is as follows:
»Baud rate: 57,600
»Data Bits: 8
»Parity: None
»Stop Bits: 1
»Flow Control: None
»Carriage Return: Required
»Line Feed: Required
Pin 5 – Ground
Pin 3 – Receive
Pin 2 – Transmit

NOTE: All commands are case-insensitive. Spaces are shown for clarity; all commands should not
have any spaces. Every command below requires a carriage return at the end of the string for the
command to be executed. If a new line character is received, a prompt should be sent back.

½STA: Status Command - Displays unit status for all internal variables such as Video Input, and
EDID selected for each Input.
½PF: Power Off - Power Off command
½PN: Power ON - Power ON command
Commands:
Video Switch:
»‘SP O xx SI yy’ To switch the desired Video Input to the desired Output:
»Where xx = the Output number [01-04] –OR- [A] for ‘All’
»Where yy = the Input number [01-04] –OR- [U, D] for ‘Up’,’ Down’ respectively.
»‘U/D’ will increase/decrease the input number from its current position.
»This command will switch Inputs to your desired Output.
»Example: To switch Input 3 to Output 1, issue the command; ‘SPO01SI03’
»Example: To incrementally switch the Input Up from its present number for Output 1, issue
the command: ‘SPO01SIU’
»Example: To switch All Outputs to Input 3, issue the command: ‘SPOASI03’
EDID Copy and Default EDID Library:
»‘SP C EDID xx H/D yy’: To Copy EDID to Input from HDMI Output, or from a Default Library
»Where xx = Input numbers [01=04] –OR- [A] for ‘All’ Inputs
»Where H = EDID Copy from HDMI Output
»Where D = Default EDID Library selection (see list below)
»Where yy = Output numbers [01-04] when ‘H’ variable is selected
–OR-
Default EDID library settings [01-09] when ‘D’ variable is selected.
»This command will either copy the EDID information from a selected Output to a specific
Input (or All Inputs), or, write EDID information from an internal library of default EDID settings
to a specific Input (or All Inputs).
»Example: To copy the EDID information from HDMI Output 2 to Input 4, issue the command:
‘SPCEDID04H02’
»Example: To write the EDID information from the built-in default EDID library using default
EDID 1 to Input 2, issue the command; ‘SPCEDID02D01’

05 3D w/ PCM 2ch Digital Audio
Front Panel Buttons Enabled/Disabled:
»‘SP C FB E/D’
»Where ‘E’ will Enable the front panel buttons and ‘D’ will Disable the front panel buttons.
»Example: To Disable the front panel buttons, issue the command; ‘SPCFBD’
Reset to Factory Defaults:
»‘SP C DF xx’
»Where ‘xx’ = [01-09] and is the default EDID library loaded during a factory reset.
»This command will return the unit to its factory default settings including a user chosen
default EDID setting. (See above for a list of possible default EDID library settings available)
»Example: To reset the unit to factory default with an EDID setting of 1080i 2CH PCM, issue
the command; ‘SPCDF01’
»Example: To reset the unit to factory default with an EDID setting of 3D 1080p 2CH PCM,
issue the command; ‘SPCDF07’
