IR Remote Control
The IR Remote Control included with KD-VW4x4Pro provides
convenient, but limited control of the switching features and
unit setup.
In addition to discrete power on, power off buttons and
function buttons R1, R2, and R3, there are 3 main groups of
controls:
»A. Output Selection or Video Wall Selection
»B. Input Selection or Source Type
»C. Device Select buttons.
›The remote is powered by a CR2025 type battery
›The circular IR sensor accepts control signals from the
remote control.
The sensor is located on the center of the front panel.
Matrix Switching via IR
To execute a matrix switching command, press the desired
Output number, or “ALL” (A) and then the desired Input
number (B).

More information can be found on the Video Wall Modes section for a more in-depth description of
the modes.
EDID Control via IR
KD-VW4x4Pro has a built-in library of 5 EDID settings and the ability to copy EDID data from any
output specified via IR, RS-232, and TCP-IP. EDID Control setup via RS-232 and TCP-IP can be
found in the RS-232 Commands and Protocol TCP-IP Setup and Control sections.
›Set to Default EDID
»To change the EDID settings for a particular input via IR, press the following buttons on the
IR remote control: R2
» R1 » R3 » B » C
»B= Desired Input to provide EDID. Chose from Input buttons 1-4 (B)
»C= Desired Default EDID. Chose a number from below to the corresponding Device

»B= Desired Input to provide EDID. Chose from Input buttons 1-4 (B)
»A= Desired Output to copy EDID from. Chose from Output buttons 1-4 (A)
EDID Control
EDID authentication is provided from the KD-VW4x4Pro unit to the connected input / source
device. The EDID file (AKA “handshake”) is selected by using the IR remote or RS232/TCP-IP
commands. This file provides a list of compatible video and audio formats as well as digital data,
informing the source device what it should output. Most sources will comply with a new EDID file
without a power-cycle, but each source may behave differently.

Addressing via IR
The KD-VW4x4Pro may be addressed to avoid controlling multiple units with one IR remote. Once
applied, all IR remote controls must precede with a two digit number before sending the IR remote
control. The default address is 00.
›Set a two-digit address to your KD-VW4x4Pro unit
»Press the following buttons on the remote control: R3 » R1 » R2 » C
1
» C
2
»C
1
= Number value 0 to 9 from the Device Select Number Pad (C)
»C
2
= Number value 0 to 9 from the Device Select Number Pad (C)
›Example: If you want to set the system address to 05, using the IR remote, the sequence must
be: R3 » R1 » R2 » 0 (Device Select) » 5 (Device Select)
If a unit address other than 00 is applied, all commands via IR will require an address prefix. The
address prefix is entered using the Device Select buttons.
›Example: If system address is 02 and you want to set all outputs to input 1, using the IR remote,
the sequence must be:
0 (Device Select) » 2 (Device Select) » ALL (Output Selection) » 1 (Input Selection)
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.
Video Wall Modes
KD-VW4x4Pro supports 8 video wall modes:
# Video Wall Mode Configuration
12 Vertical x 2 Horizontal
21 Vertical x 4 Horizontal, Rotated Displays CCW
34 Vertical x 1 Horizontal
41 Vertical x 4 Horizontal
51 Vertical x 3 Horizontal
63 Vertical x 1 Horizontal
71 Vertical x 2 Horizontal, Mirrored
82 Vertical x 1 Horizontal, Mirrored
Important Note about Source Content:
It is necessary to obtain/create content that maintains the aspect ratio of the video wall mode.
»A common display’s aspect ratio is 16:9.
»Example: Working in the 4V x 1H mode, the width is 1 to 1 (1:1), but the height is 1 to 4
(1:4) because of the 4 vertical displays.
»Therefore, the correct source content should be 16:36
»Tip: 16 times 1 equals 16 for the width. 4 times 9 equals 36 for the height.
