Using Preset Values
When a command is entered, the VGA & Audio to HDMI Scaler/Converter will conrm the
entry by returning the function of the command and any parameters. There are several
commands which use a preset value as one of the parameters. When specifying a preset
value as a parameter, the returned preset value will always be one greater than the value
that was specied.
For example, if we look up the #get_timing_preset command, we will see that this
command accepts a single preset value, where param1 is a value from 0 to 5:
#get_timing_preset [param1]
If we set param1 = 2, then the return value will be displayed as 3:
#get_timing_preset 2
