IR Emitter Control
When using an IR Emitter / IR Extender (sold separately), the IR Emitter must be mounted over
the IR Sensor on the front of the KD-MLV4x2Pro. 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-MLV4x2Pro.
Serial IR Control
As a more robust alternative to optical IR, KD-MLV4x2Pro may also be controlled via hard-wired
IR. Use a 3.5mm Male Mono plug with the IR Signal carried on the tip of the connector.
Rack Mounting
Secure the rack ears to each side of the KD-MLV4x2Pro with the supplied hardware then fasten
the unit to the rack rails with the included machine screws.

Front Panel Operation
Mode Select Input SwapLCD Screen HDMI/VGA Input Select
The front-panel of KD-MLV4x2Pro features 3 sets of buttons:
HDMI / VGA input-type select (2 buttons)
› Enables selection of the HDMI digital video input or VGA analog video input for the specified
source
» Note: Selection of VGA or Component video input type for the Analog Video input must be
done by RS-232 or TCP-IP
› To select HDMI or VGA input type:
» 1. Press either HDMI or VGA, as desired
» 2. Using the Output 1 row of buttons, press the desired input number that you’d like to
apply the setting to
» 3. Confirmation of your selection is shown on the LCD screen
» a. Example: When input 1 input-type has been set to VGA, the LCD screen will show
[A/V SOURCE ] INPUT 1 = VGA
Matrix switching source select (2 rows of 6 buttons)
› Enables selection of any input source (1-4) for the respective output, or to enter 4K Quadrant or
2K Quadrant modes
» 2K QV mode divides the image into 4 equally-sized quadrants
» 4K QV mode divides the image into 4 equally-sized quadrants
» The overall image is 4K, making each quadrant a full-1080p resolution
› The selected source is indicated by a blue fill of the respective button
› If any 4K or 2K QV quadrant modes are chosen, the Matrix switching source select buttons will
not be illuminated for the respective output
› Confirmation of your matrix switching selection and respective input-type for selected source is
shown (in parenthesis) on the LCD screen:
» OUT 1: IN 1 (HDMI)
» OUT 2: IN 2 (VGA)
› Confirmation of 4K quadrant mode and respective input-type for sources (in parenthesis) is shown

1080p(2K) Multi-View mode select (5 buttons) and Input Swap (1 button)
› Pressing any of the 5 Multi-View mode select buttons will activate both outputs to
simultaneously enter the selected screen layout
»
IMPORTANT:
Selecting 2K Multi-View mode results in linking of the two KD-MLV4x2Pro

5. Right
› If desired, the layouts can be over-written via the Web Control Interface, RS-232, or TCP-IP, by
saving to the KD-MLV4x2Pro’s preset bank
› Resetting the KD-MLV4x2Pro to factory default will restore these 5 layouts in the preset bank as
layouts 1-5, respectively.
› The
Input Swap
button serves 2 purposes:
» 1. If used in standard 4x2 matrix, full-screen mode, pressing Input Swap will simultaneously
and synchronously switch both outputs:
» 2. If used in Multi-View mode, pressing Input Swap rotates source content of the 4 inputs
through the 4 windows:
› Confirmation of 2K multi-view mode and respective input-type for sources (in parenthesis) is
shown on the LCD screen:

IR Remote Control
The IR Remote Control included with KD-MLV4x2Pro provides
convenient but limited control of the switching features and unit setup.
There are 3 main groups of controls:
› Group for output 1 source and 2K / 4K output resolution select
› Group for output 2 source and 2K / 4K output resolution select
› Group for device select buttons
› Additionally, there are discrete power on and off buttons and
function buttons R1, R2, and R3.
» The remote is powered by a CR2025 type battery
» The circular IR sensor accepts control signals from the
remote control. The sensor is located in the center of the
front panel.
Switching via IR
To execute a switching command, press the desired source select
button within the desired output button group.
Multi-View Modes via IR
1080p (2K) Multi-View presets can be called using the IR remote by pressing the following remote
button sequence:

Addressing via IR
To apply a two-digit address to your KD-MLV4x2Pro unit, press the following buttons on the
remote control:
R3, R1, R2, X1, X2
. X1 and X2 are chosen using the Device Select number pad.
» 00 is the default unit address
If a unit address other than 00 is applied, all commands via IR will require an address prefix, XX.
The address prefix is entered using the Device Select buttons. RS-232 and TCP-IP codes also
require an address prefix if an address other than 00 is applied. More information is available in
the RS-232 and TCP-IP Commands and Protocol section.

Window Transparency and Border Settings
In addition to the possible custom settings applied using the Advanced Video screen of the Web
Control Interface, window transparency and border settings can be applied to all windows in 4K or
2K Quadrant Modes, as well as 2K Multi-View mode.
At the time of introduction, window Transparency and Border settings can only be applied / viewed
via RS-232 or TCP-IP terminal. Please see the RS-232 and TCP-IP Commands and Protocol
section for additional information
Transparency
While in 4K or 2K Quadrant Modes, as well as 2K Multi-View mode, transparency can be applied
to the source windows, allowing windows in the back (ie. Layer 4) to be viewable through windows
in the front (ie. Layer 2, 3, or 4) of a custom layout.
› Transparency settings are not independent for each window.
› The possible transparency setting applied to each window is 0%, 25%, 50%, and 75%
› The RS-232 / TCP-IP command to apply transparency is as follows:
»
SPM TY z
› Set Transparency by z [0=00%, 1=25%, 2=50%, 3=75%]
Window Border
KD-MLV4x2Pro enables a border-line / bezel to be applied and customized if desired. The borderline width and color of the border-line can be specified
› The RS-232 / TCP-IP command to apply border-line width is as follows:
»
SPM BLW z
› Set Border Line Width by z [0=None, 1~9Pixels]
› The RS-232 / TCP-IP command to apply the desired color to the border-line is as follows:
»
SPM BLC rrr.ggg.bbb
» Set Border Line Color by RED/GREEN/BLUE
» (rrr=[001~255], ggg=[001~255], bbb=[001~255]
