Automatic Switch Control
The switcher supports automatic switching and allows you to control it without
staying near it or using the IR remote.
When the switcher is powered on, automatic switching will function as
follows:
1. When HDMI sources are inserted, the switcher will switch to the latest
connected source for output display.
2. When the HDMI source selected is removed, the switcher will switch to
the active source with top priority for output display (Priority: input 1 >
input 2 > input 3 > input 4).
Note: Automatic Switching function can only detects 5V of the input source
device. If the selected HDMI source in standby mode provides a continuous
5V power output, the Automatic Switching function will not work, i.e. the
switcher will not switch the input to other active sources. In this case, please
turn off the standby source device selected or remove it from the switcher.
