Operation
Matrix Switching
With all of the video and audio sources connected to the four Input Ports, and the displays and
audio systems connected to the two Output Ports of the KD-MSW4x2 unit, the matrix switcher is
ready to operate. The routing of video and audio signals from the available inputs to either output is
easily implemented using the front panel pushbuttons, and visually verifiable via the LED indicator
arrays.
The front panel of the unit provides the user with a visual representation of the two outputs.
Each of the two output sections consists of a large pushbutton switch and an array of four LED
indicators. Each of these appropriately numbered LED indicators corresponds to one of the four
available inputs.
For either display that is connected to the output of the KD-MSW4x2 unit, the desired source input
is switched by depressing the appropriate pushbutton until the LED indicator corresponding to the
chosen input is lit. The video and audio sources connected to that input are automatically switched
to the selected output. The unit also acts as a distribution amplifier, simultaneously routing a single
input to both outputs, by simply repeating the same procedure for both outputs.
Summary: Control and Monitoring
Select one of four input sources for each of the two outputs
Front-panel LEDs indicate the selected input, for each output

Fat Boy Expansion Control
Fat Boy expansions have multiple KD-MSW4x2 units pre-wired from the factory. Each unit in the
expansion is individually addressable.
Configuring a particular unit with the desired input and output combination requires the following
successive steps:
Addressing desired Unit:
Depress button 1 through 8 to select the desired unit
Addressing desired Output:
Depress button ‘output 1’ (to select Output 1), or ‘output 2’ (to select Output 2)
Addressing desired Input:
Depress numerical digits 1 to 4
Additional Product Features
Fade-to-Black
The Fade-to-Black feature allows for switching between input/output combinations without the
usual visual signal noise, glitches, and sync roll that traditionally accompany switching between
video signals. The feature momentarily forces the video image to black as the desired source
input is selected for the chosen output. This feature is applied automatically and the fade time
interval is programmable via RS-232 [see the RS-232 Command List].
Video Mute
Video Mute enables the user to mute the video signal (the display goes to black) at the chosen
output. Activated via IR remote control or RS-232 [see the IR remote control section of this
manual, and the RS-232 Command List for explicit instructions].
Distribution Amplifier
It is also possible under RS-232 control to allow any one of the four inputs to be switched and
distributed to both outputs.
Power On/Off
Turn the KD-MSW4x2 On and Off. In the power-off mode, all front LEDs are Off and the video
outputs are muted.
