4. System Operations
4.1 Front Panel Control
Front panel buttons can be used for source selections, there are 4 sources for choose
in total, including HDMI, DP, DVI, VGA. Video signals support auto-switching and
manual switching (factory default).
4.1.1 Manual-switching
Press to SOURCE/AUTO button select one source, press again to select next source,
switching sequentially between HDMI, DP, DVI and VGA.
4.1.2 Auto-switching
Press and hold for SOURCE/AUTO button for 3 seconds or more to enter in autoswitching mode. In this mode, the Scaler Switcher will follow these rules to select input
source automatically.
➢ New input:
Once detecting a new input signal, the Scaler Switcher would switch to this new
signal automatically.
➢ Rebooting device
The Scaler Switcher have the ability to save the last configuration before losing
power. If the last switching mode is auto-switching, once rebooted, the Scaler
Switcher 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, the unit will output the signal. If not, the unit will detect all the
inputs signals with priority from HDMI to VGA. When detected the first signal, it will
transfer to output.
➢ Signal removing
Once removing the current display signal, the Scaler Switcher will detect all input
signals with priority from HDMI to VGA. When detected the first signal, it will
transfer to output.
Notice:
In manual-switching mode, if you set the signal format of VGA/DVI input
to C-video or YPbPr, the system will not be able to enter Auto-switching
mode.
In auto-switching mode, if the signal format of DVI input is C-video/YPbPr,
the Scaler Switcher can’t detect the DVI input, the command 50686%
should be sent via PC to convert C-video/YPbPr into digital signal format,
and then the Scaler Switcher will enter
In auto-switching mode, select input source via front panel button is not
available, but RS232 command and IR remote are able to switch mode.
