KD-MSW4x2 Operating Instructions

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.

Input 1, 2, 3, and 4 LED indicators

Use this front-panel pushbutton to select any of the up to four source input devices to drive the display and audio system wired to Output 1. Press the button and cycle through Input 1, 2, 3, and 4.

Repeat for Output 2 using the appropriate Output 2 pushbutton and LEDs for monitoring the input selection.

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

Control via:

KD-MSW4x2 Operating Instructions

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:

1.Addressing desired Unit:

Depress button 1 through 8 to select the desired unit

2.Addressing desired Output:

Depress button ‘output 1’ (to select Output 1), or ‘output 2’ (to select Output 2)

3.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.
