AUTO SWITCHING
The switch supports both automatic and manual switching modes. When automatic
switching mode is enabled, it functions according to the following principles.
When a new input signal is detected, the unit will automatically switch to that
input.
When the unit is powered off, it remembers the last selected input and will return
to that input when power is reapplied. If the last input is no longer available, the

9
unit will detect all inputs in the order HDMI 1 > HDMI 2 > HDMI 3 > HDMI 4 > VGA
and will automatically select the first active input.
If the currently selected input is removed, the unit will detect all inputs in the order
HDMI 1 > HDMI 2 > HDMI 3 > HDMI 4 > VGA and will automatically select the first
active input.
VGA INPUT
The VGA input can accept VGA, Component (YPbPr), and Composite (CVBS) video signals.
The unit will automatically detect the input type and will convert and scale it to the HDMI®
output.
When connecting to a VGA input, use a standard DB15 VGA cable (not included).
When connecting to a Component (YPbPr) video source, connect the Red, Blue, and
Green plugs to the corresponding video outputs on your Component source device.
When connecting to a Composite (CVBS) video source, plug the red connector into
the video output (normally yellow).

INSTALLATION
Perform the following steps to install this switch.
1. Ensure that all equipment to be connected is powered off and unplugged from its
power source.
2. Using a High Speed HDMI® Cable (not included), plug one end into the HDMI input
on your display, then plug the other end into the HDMI port in the OUTPUT section
on the scaler/switcher.
3. Using the included audio cable, plug one end into the 3.5mm AUDIO jack in the
OUTPUT section, then plug the other end into the inputs of powered speakers, a
stereo amplifier, or other analog audio device.

11
4. Using a High Speed HDMI® Cable (not included), plug one end into one of the HDMI
ports in the INPUT section on the scaler/switcher, then plug the other end into the
HDMI output on your video source device. Repeat for up to three additional HDMI
video sources.
5. Using a VGA cable, plug one end into the VGA port in the INPUT section on the
scaler/switcher, then plug the other end into the VGA output on your computer,
laptop, or other device. Alternatively, plug the included video cable into the VGA
port in the INPUT section on the scaler/switcher, then plug the other end into the
RGB outputs of a component (YPbPr) video source or plug the red connector into
the video output jack of a composite (CVBS) video source.
6. Using a 3.5mm audio cable (not included), plug one end into the AUDIO jack in the
INPUT section on the scaler/switcher, then plug the other end into the audio output
jack on your computer or laptop. Alternatively, using the included audio cable, plug
one end into the AUDIO jack in the INPUT section on the scaler/switcher, then plug
the other end into the stereo RCA audio output on your component or composite
video source device.
7. (Optional) If you want to use your computer for RS232 control of the
scaler/switcher, plug one end of a serial cable (not included) into the 3-pin RS232
terminal block in the CONTROL section on the scaler/switcher, then plug the other
end into one of the COM ports on your computer or laptop.
8. (Optional) If the IR "eye" on the front panel will be obscured, such as when installing
this system into a closet or cabinet, plug the included IR receiver into the IR jack in
the CONTROL section on the scaler/switcher, then position the IR "eye" where it can
receive IR signals from the included remote control.
9. Plug the DC barrel connector on the included AC power adapter into the 12V DC
jack on the scaler/switcher, then plug the adapter into a nearby AC power outlet.
10. Plug in and power on all connected equipment, then start video playback on all
video source devices. Verify that the video from each device can be viewed on the
connected display and that the audio can be heard.
