ASCII a (or Hex 61)
Enters ‘Auto’ mode.
In Auto mode, the device automatically switches to the
video & audio input source that is active. “Active” means
that video signal has sync signal, it does not mean there is
a non-static screen!
ASCII s (or Hex 73)
Enters ‘Scan’ Mode.
The user is first prompted to enter the switching time
delay from 1-60 seconds.
“Seconds between switching? (1-60)”
The users are then prompted to select whether ‘non-
active’ video input channels should be scanned or not.
“Scan non-active? (Y/n)”
ASCII b (or Hex 62)
Blanks the output. When the output is blanked, only the
color intensities of the output are reduced to zero
(resulting in a black screen), the unit still operates in
normal fashion and sync signals are still routed to the
output. Audio output is muted.
ASCII u (or Hex 75)
Un-blanks the output.
