Model #:  KD-MSW4x2Pro — 

4 Inputs to 2 Outputs HDTV Matrix Switcher

The Fat Boy Series KD-MSW4x2Pro by Key Digital

‚ is an analog HDTV 4-Input to 2-Output matrix 

switcher and distribution amplifier. 

Matrix Switching

Supports Video and Audio 
Four (4) Input Ports and two (2) Output Ports provided
Matrix switch one of up to four inputs to either of two outputs

For each of the two outputs that can be used to drive separate displays, one of the four 

source inputs can be 

independently

 selected

Also acts as a distribution amplifier, simultaneously routing any individual input to both outputs

Using RS-232 control

Analog Audio Volume Control with Muting provided

Expandable

The KD-MSW4x2Pro Fat Boy expansions have four (4) Input Ports and expanded Output Ports:

KD-MSW4x4Pro

4 output ports

KD-MSW4x6Pro

6 output ports

KD-MSW4x8Pro

8 output ports

Professional Switching Features

Fade-to-Black: 

 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
Fade time interval is programmable via the RS-232, and is equivalent to a “Video Mute” to 

force the video to black during switching

See the RS-232 Command List

Video Mute:

 enables the user to mute the video signal (the display goes to black)  

at the chosen output

»

note:

  The following Technical Specifications are for a base KD-MSW4x2Pro HDTV Matrix 

Switcher.  The Technical Specifications for Fat Boy expansion configurations scale accordingly, with 

the outputs incrementing in steps of two (2).  The expansion packages are comprised of multiple 

KD-MSW4x2Pro units ganged together and tested from the factory with a special cable kit.   

output set up command: 

 

IR: R1 

 7 : RGBHV mode 

 

R1 

 8 : Component mode 

 

RS-232 : CCOR : RGBHV mode 

 

CCOC : Component mode (factory default) 

 

note: 

  If this bit is not set correctly, the Video Mute function will not work and the user I 

not able to see any output video. 
If the KD-MSW4x8Pro is set to RGBHV mode, none of the volume control 
commands ( IR /  RS-232 ) will work.

Factory default command: 

 

CCF0 : Resets memory 

 

 

Inputs for every output = 1 

 

 

Mute Interval = 240 ms 

 

IR Remote Control commands: 

 

I : Disable IR Remote Control 

 

u : Enable IR Remote Control

 Front Panel Pushbutton commands:

 

 

d : Disable front panel pushbutton controls 

 

e : Enable front panel pushbutton controls

 Switching any input to both outputs commands (Distribution Amplifier mode): 

 

z<number(1~4)> : Switches both outputs to any one input temporarily;   

 

 

             can be restored to original selection 

 

For Fat Boy expansions, ALL outputs follow the selected input 

 

z0 : Restores the original input-output configuration 

 

 

Example: 

 

z3 : Switches both outputs to input 3

 Volume Control commands: 

 

 CCV<output( 1~2 )><volume( 00~30 )>  : Adjusts analog stereo L&R volume 
Default : ‘15’ [unity-gain through the product] 
Level ‘00’ can be used as mute
