KD-MSW4x2 Operating Instructions

4.Video Mute command:

IR : R1‡ output 1-2 ‡ Up arrow : Enable Mute

R1 ‡ output 1-2 ‡ Down arrow : Disable Mute

Example:

R1‡ output 1 ‡ Up arrow : output 1 is muted

Note:	R1‡ U4 ‡ Up arrow mutes every output
	RS-232: CCm<number(1~3)> : Enable mute
	CCn<number(1~3)> : Disable mute

5.Fade to Black interval set up command:

Period that will be muted is twice the interval

CCi<number(0~9)>

CCI0 : No mute

CCI1 : 28 ms mute

CCI2 : 40 ms mute

CCI3 : 80 ms mute

CCI4 : 120 ms mute

CCI5 : 160 ms mute

CCI6 : 240 ms mute

CCI7 : 320 ms mute

CCI8 : 400 ms mute

CCI9 : 600 ms mute

6.Power On/Off

s : Power OFF the KD-MSW4x2 unit

q : Power ON the KD-MSW4x2 unit

7.Output set up command:

IR: R1 ‡ 7 : RGBHV mode

R1 ‡ 8 : Component mode

RS-232 : CCOR : RGBHV mode

CCOC : Component mode (factory default)

8.Factory default command: CCF0 : Resets memory

Inputs for every output = 1 Mute Interval = 240 ms

9.IR Remote Control commands:

I :Disable IR Remote Control

u :Enable IR Remote Control

10.Front Panel Pushbutton commands:

d : Disable front panel pushbutton controls

e : Enable front panel pushbutton controls

11.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

z0 : Restores the original input-output configuration

Example:

z3 : Switches both outputs to input 3

KD-MSW4x2 Operating Instructions

Model #: KD-MSW4x2

4 Inputs to 2 Outputs HDTV Matrix Switcher

The Fat Boy Series KD-MSW4x2 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

›Expandable

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

Input/Output Ports and Formats

›The output format = the format of the selected input source

›Each Input and Output Port is comprised of six (6) color-coded RCA jacks:

➔3 analog video connectors

➔2 analog audio connectors

»The analog audio input/output connectors also serve as the horizontal and vertical sync for RGBHV signals

›1 PCM digital coax audio connector
