System 7SC • Operation and Configuration
If the autoselect feature is on, the last input (input 7 if no slave is attached) is
selected, and video signals are present at all ports for that input, computer
video (RGB) will be selected as the default source.
Inputs are autoselected as follows:
• RGB input (highest priority),
• S-video input,
• composite video input (lowest priority).
The LCD will display Autoselect #7 if the System 7 is not set up for a slaved
switcher. If a switcher is slaved to the System 7, the LCD will display
Autoselect #10, Autoselect #12, Autoselect #14, or Autoselect #16, depending
on the size of the slaved switcher.
