Quick Setup Guide:

1. Begin with the KD-2x2CS and all input/output devices turned off and power cables removed.

2. Connect HDMI sources to the appropriate input ports on the KD-2x2CS.

3. Connect HDMI outputs to the appropriate output device (display, projector, AV Receiver, etc).

4. Connect power to the KD-2x2CS as well as to all other input and output devices
and turn them on.

5. Operate the KD-2x2CS 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-2x2CS features a library of 12 internal EDID (Extended Display Identication Data)
les, 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 “04” – 1080p 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 ‘12’. (‘01’ is the default).

01 1080i, 2CH Audio 07 3D, 2CH Audio

02 1080i, DOLBY/DTS 5.1 08 3D, DOLBY/DTS 5.1

03 1080i, HD Audio 09 3D, HD Audio

04 1080p, 2CH Audio 10 1280x1024 DVI

05 1080p, DOLBY/DTS 5.1 11 1920x1080 DVI

06 1080p, HD Audio 12 1920x1200 DVI

When selecting an EDID from the library (settings 01-12), your source device will “see” the KD­2x2CS EDID choice instead of the display’s EDID, overriding the display’s 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 hear 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-2x2CS switching commands by
using the supplied IR Remote control. There are 2 groups
of controls, one group for each Output. Each Input can be
selected by pressing the Input numbers 1-2.

» Baud rate: 57,600

» Data Bits: 8

» Parity: None

» Stop Bits: 1

» Flow Control: None

» Carriage Return: Required

» Line Feed: Required

Pin 5 – Ground

› STA: Status Command - Displays unit status for all internal variables such as Video Input, and

EDID selected for each Input.

› PF: Power Off - Power Off command
› PN: Power ON - Power ON command

Commands:

Video Switch:

» ‘SP O xx SI yy’ To switch the desired Video Input to the desired Output:

» xx = the Output number [01-02] –OR- [A] for ‘All’

» yy = the Input number [01-02] –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.

KD-2x2CS_Manual.indd 4-5 1/18/13 1:17 PM

» Example: To switch Output 1 to Input 2, issue the command; ‘SPO01SI02’

» 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 2, issue the command: ‘SPOASI02’

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

» xx = Input numbers [01-02] –OR- [A] for ‘All’ Inputs

» H = EDID Copy from HDMI Output

» D = Default EDID Library selection (see list below)

» yy = Output numbers [01-02] when ‘H’ variable is selected

–OR-
Default EDID library settings [01-12] when ‘D’ variable is selected.

» This command will either copy the EDID information from a selected Output to a specic

Input (or All Inputs), or, write EDID information from an internal library of default EDID settings

to a specic Input (or All Inputs).

» Example: To copy the EDID information from HDMI Output 2 to Input 2, issue the command:

‘SPCEDID02H02’

» Example: To write the EDID information from the built-in default EDID library using default

EDID 1 to Input 2, issue the command; ‘SPCEDID02D01’

» The possible EDID settings can range from ‘01’ to ‘12’. (‘01’ is the default).
