Operation and Configuration, cont’d

An LED near each video connector indicates which input type is active. Select “Yes” from the Autoselect #7 submenu to activate autoselection.

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.
