4. System Operations
4.1 Front Panel Button Control
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, SC61E would switch to this new signal automatically.
Rebooting device principle
The SC61E has the ability of power-off memory. If the last switching mode is
auto-switching, once rebooted, it 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, It 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, Compact Scaler Switcher will detect all input
signals with priority from HDMI1 to VGA2. It will transfer the signal first 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.

ALFATRON ALF-SC61E

Remove the signal of HDMI3, Compact Scaler Switcher will detect from HDMI1 to
VGA2. And when it detects that HDMI2 is available, it will choose HDMI2 to output.
Cut off the power of Compact Scaler Switcher, then reboot. As the unit 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 Compact
Scaler Switcher.
Uninstallation Delete all the control software files in corresponding file path.
4.2.2 Basic Settings
