½ HDMI Inputs: The 4 HDMI Inputs are located in the center of the back panel. The Inputs have a
blue LED which will light when a source is connected and synced.
½ HDMI and CAT5e/6 Outputs: There are 4 sets of HDMI Outputs and their associated CAT5e/6
Outputs located on either side of the HDMI Inputs. Both HDMI and CAT5e/6 Outputs have a
blue LED which will light when a display/Balun is connected and synced.
½ The HDMI and CAT5e/6 Outputs are both active simultaneously.
½ There are 4 Serial IR Inputs located on the right side of the back panel. These are standard
3.5mm mono jacks. Connect these to any control system for routing IR over the CAT5e/6
outputs.
½ The 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 only 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.
½ If newer firmware is made available, complete updating instructions will be included with it.
Check the Key Digital website for any firmware updates.
Front Panel Buttons and LED’s:
Output Select Buttons
Input LEDs
IR Eye
½ There are 4 Output buttons along the front panel.
½ Each press of an Output button cycles through each of the 4 Inputs.
½ A blue LED will indicate which Input has been selected for each Output button.
½ There is also an Optical IR window located on the right side of the front panel for the remote
control signals.
KD-CATHD4x4Rx Baluns
If you will be utilizing the KD-CATHD4x4Rx Baluns (included), please follow this procedure.
½ 2 CAT5e/6 UTP or STP cables need to be used.
½ Be careful to connect the “Video/Audio” jacks
to each other and the “Data” jacks to each
other. Do not cross these connections.
½ Use the shortest length HDMI cable you can
when connecting the Balun to the Display.
½ Ensure that the 2 cables are run directly from
the switcher to the Baluns.
½ Do not use patch panels, punch downs or wall plates.
½ Each Balun is supplied with a power supply.
½ Key Digital recommends the use of CAT5e/6 STP cable with shielded RJ45
connectors for optimum performance and distances from your Balun.

Transmitting IR signals with KD-CATHD4X4Rx Baluns
KD-4x4XC can consolidate incoming IR signals to control display/output devices when integrated
with KD-CATHD4x4Rx.
The IR Signal flows only in one direction; from Input (Matrix) to Output (Balun). It cannot be used to
route IR signals from Output (Balun) to Input (Matrix).
The default signal path for Expansion Serial IR Input 1 is output of KD-CATHD4x4Rx output #1 and
continues respectively through Input 4 with Output 4. However, the Input/Output relationship can
be manipulated in full matrix functionality vai RS-232.
When connecting the IR Emitter to the device you wish to control, make sure to find the IR receiver
area on your particular device first. Experiment with locations and test the functionality before
permanently fixing it.
Application Example
Quick Setup Guide:
Connections
1. Begin with the KD-4X4XC and all input/output devices turned off and power cables removed.
2. Connect HDMI sources to the appropriate input ports on the KD-4X4XC.
3. Connect either or both HDMI and CAT5e/6 outputs. You will require 2x CAT5e/6 UTP or STP
cables for each Balun connected.
4. Connect power to the KD-4X4XC as well as to all other input and output devices and turn
them on.
5. Operate the KD-4X4XC 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-4X4XC features a library of 9 internal EDID files, in addition to allowing the Input source to
receive a copy of the EDID information of any selected Output connected via HDMI or CAT5e/6.
The default EDID setting is “01” - 1080i w/ PCM 2ch Digital Audio. Changing to different 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.
Available EDID library settings: (‘01’ is the default)
01
1080i w/ PCM 2ch Digital Audio
06
3D w/ Dolby Audio
02
1080i w/ HD Audio
07

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 KD4X4XC 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.

» 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’

» Where xx = Output numbers [01-04] –OR- [A] for ‘All’ Outputs
» Where yy = Serial IR Input numbers [01-04] or [U, D] for ‘Up’,’ Down’ respectively. ‘U/D’ will
increase or decrease the IR input number from its current position.
» This command will rout the selected Serial IR Input number [1-4] to the desired Output
number over the CAT5e/6 connection.
» Example: ‘SPOASR02’: Will carry IR from IR Input port 2, to ‘All’ Outputs.
‘SPO02SR01’: Will carry IR from IR Input port 1 to Output 2.
EDID Copy and Default EDID Library:
» ‘SP C EDID xx H/C/D yy’: To Copy EDID to Input from Output via HDMI or CAT5e/6, or from

Light Buffer Technology (LBT™)
Light Buffer Technology Dynamic Signal Re-Clock
½ Multiple output viewing mode is supported by a dynamic realignment in clocking that may
appear as a short blink when multiple display/outputs select a single source/input.
½ This dynamic re-clocking improves video quality on all displays and does not affect performance
during non-switching operation.
½ Full Buffer operation can be achieved with the use of KD-HDDA1x1 (sold separately)
Light Buffer / Full Buffer
½ KD-4x4XC: Light Buffer Product
» Each input buffer of KD-4x4XC has a capacity to enable one or more outputs. As displays
select/de-select the input source, the input buffer capacity increases/decreases accordingly
» i. This process is referred to as “dynamic re-clocking”
½ Performance of stand-alone KD-4x4XC (with or without included KD-CATHD4x4Rx baluns):
» Any time more than 1 display views a source, the change in input buffer capacity results in a
blinking of all displays viewing that source
» Operation is not effected during non-switching operation
½ KD-HDDA1x1 (sold separately): Full Buffer product installed for each matrix input:
» The source device is now connected to the input of KD-4x4XC through the KD-HDDA1x1
instead of direct connection.
» The KD-HDDA1x1 effectively increases the KD-4x4XC’s input buffer and overall capacity
enabling switcher outputs. As a result, dynamic re-clocking is performed mush faster
thereby removing blinking when more than one display is connected to a respective input.
½ Performance of KD-4x4XC with each source installed via KD-HDDA1x1:
» Synchronization within the KD-4x4XC assumes all 4 displays will view the source and may
result in a slightly longer initial switch time from the un-viewed state
» This synchronization process occurs only during the initial selection of the source. That is,
when the source is selected from being in an un-viewed state
» Switching to a source that is currently viewed by other zones will no longer result in blinking
or any increase in switching time.
