Control Connections
Decide how the KD-MSW4x2 will be controlled
If using an IR (Infrared) Extender, the wired IR, or an external Control System (via the RS-232 port
on the KD-MSW4x2), make the appropriate connections
Power
Use ONLY the external power supply provided with the KD-MSW4x2 unit. Use of any other
power supply VOIDS the Key Digital
™
Warranty and may
potentially damage the unit and any associated equipment.
Connect the external power supply provided with the
KD-MSW4x2 to the jack on the rear panel of the unit.
Connect the power supply to an appropriate source of power,
such as from a wall outlet.
Operation
Follow all manufacturer instructions for the safe and proper operation of the source and display
products that have been connected to the KD-MSW4x2.
Using one of the convenient control options for the KD-MSW4x2, separately select source input
1, 2, 3, or 4 for output display 1, and source input 1, 2, 3, or 4 for output display 2.
Use the IR remote control with an extensive command and control capability.
See the description for the IR remote control provided later in this Operating Manual.
It is also possible under RS-232 control to allow any one of the four inputs to be switched and
distributed to both outputs [see the RS-232 Command List].

Additional Product Features
Several new features have been added to this generation of Key Digital
™
switchers, called “Fade-to-
Black” and “Video Mute.” Both of these features let the user switch like a pro, like in a live studio.
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.
Video and Audio Mute
Video and Audio Mute enables the user to mute the audio and video signal (the display goes
to black) at the chosen output, using the RS-232 [see the RS-232 Command List] or IR remote
control. Using the IR remote control for Video and Audio Muting:
Activate Video & Audio Mute:
R1 ‡ output (1~2) ‡ up arrow
Deactivate Video & Audio Mute: R1 ‡ output (1~2) ‡ down arrow

IR Remote Sensor
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.
Input 1, 2, 3, and 4 LED indicators
Note: Since the KD-MSW4x2 Matrix Switcher does NOT perform video processing,
the output video format is the same as the input video format. This means that the
video resolution is not changed and also that form of video is input to the unit, for
example Component Video, the output will be in exactly the same format.
