4. System Operations
4.1 Front Panel Button Control

Compact Scaler Switcher 6x1
Front panel buttons can be used for source selections, output resolution adjusting, front
panel buttons management, software updating and output screen setting. (Please refer
to chapter 2.1 ).
Here is the detail information for source selections:
There are 6 sources for choose in total, including HDMI1, HDMI2, HDMI3, HDMI4,
VGA1, VGA2. Video signals support auto-switching and manual-switching (factory
default). Press and hold for SOURCE/AUTO for 3 seconds or more to enter in auto-
switching/ manual-switching mode.
Manual-switching:
Dial ◀to select the previous source, dial ▶to select the next source.
Auto-switching:
In this mode, select input source via front panel button (◀▶) is not available, but
RS232 command and IR remote are able to switch mode. The auto LED turn green and
keep on.
The auto-switching mode abides by the following principles:
New input principle
Once detecting a new input signal, VL120002 would switch to this new signal
automatically.
Rebooting device principle
VL120002 have the ability of power-off memory. If the last switching mode is auto-
switching, once rebooted, VL120002 will automatically enter auto-switching mode, and
then detect all inputs and memorize their connection status for future rebooting using. If
the last displayed signal is still available, VL120002 will output the signal. If not, the unit
will detect all the inputs signals with priority from HDMI1 to VGA2. When detected the
first signal, it will transfer to output.
Signal removing principle
Once removing the current display signal, VL120002 will detect all input signals with
priority from HDMI1 to VGA2. It will transfer the signal firstly detected to be available to
output devices
Operation Examples:
Connect HDMI2, HDMI4, and VGA2 ports with source devices, select HDMI4 to
outputs.
Press and hold for the front button SOURCE/AUTO for 3 seconds or more to enter
in auto-switching mode.
Connect HDMI3 with a source device, and then it will choose HDMI3 to output.
Remove the signal of HDMI3, VL120002 will detect from HDMI1 to VGA2. And

Compact Scaler Switcher 6x1
when it detects that HDMI2 is available, it will choose HDMI2 to output.
Cut off the power of VL120002, then reboot. As VL120002 is in auto-switching
mode, it will choose HDMI2 to output.
4.2 RS232 Control
Here we take the software CommWatch.exe as example.
4.2.1 Control Software Operation
Installation Copy the control software file to the computer connected with
VL120002.
Uninstallation Delete all the control software files in corresponding file path.
4.2.2 Basic Settings
Firstly, connect VL120002 with an input device and an output device. Then, connect it
with a computer which is installed with RS232 control software. Double-click the
software icon to run this software. The icon is showed as below:
