VGA/Stereo Audio Selection Switcher 4X1 6. System Diagram 7. Auto-switching Function Under the auto-switching mode, WVG4A will detect the input source and switching automatically, following some priority principle: 1: Priority of the new connection When you connect a new valid VGA source to WVG4A, under the auto-switching mode, WVG4A will switch to this new source.
VGA/Stereo Audio Selection Switcher 4X1 EXAMPLE: Connect the input 2 and input 4 ports to the source devices, press and hold on the front key INPUT 1 for 3 seconds, the LED indicator Auto-SW will be on. Then WVG4A begins to run in auto-switching mode. WVG4A detects the signal from the port input 1 to input 4 one by one. When it detects that input 1 is not available, and then it turns to detect input 2.
