5.5 Auto-Switching Function
This switcher has auto-switching and manual-switching modes. When you
select auto-switching mode, it will follow these rules:
5.5.1 New Input principle
5.5.2 Power rebooting principle
5.5.3 Signal removing principle
Once a new input signal is detected, the switcher will switch to this new
signal automatically.
This switcher offers the function to remember the signal last used after
rebooting. Once rebooted, it will automatically enter auto-switching mode,
and then detect all inputs and memorize their connection status for future
reboots. If the last used input signal is still available, then it will choose and
display that signal. If that signal is not available, it will detect all input signals
with priority on HDMI1->HDMI2->HDMI3->HDMI4->VGA(YPbPr/CVBS).
Once the current signal is removed, the switcher will detect all input signals
with priority on HDMI1->HDMI2->HDMI3->HDMI4->VGA(YPbPr/CVBS). It
will transfer the rst signal detected to the output.
Note: Auto-switching function works only when there is a new input signal
or when the current input signal is removed.

5.6 VGA/YPbPr/CVBS Input
The VGA input port supports multiple signal formats, such as VGA/YPbPr/
CVBS. The switcher will auto-detect the input signal type and format. You
can use the convert cable for YPbPr or CVBS signal input.
5.7 Operations of RS-232 Control
