Section 2— Startup and Configuration
Configuring Switcher Inputs
Primary video and key inputs to the switcher are numbered 1 
through 64. Any of these inputs can be treated as either a video 
signal or a key signal.
Each input, including Black and Background, can be mapped to 
any vertical column of source select (“crosspoint”) buttons.
NOTE:  
The external video and key assignments are set up following 
installation to correspond to the video and key inputs connected to the 
frame. These assignments should never be changed by the operator.
Internally-generated sources (black, backgrounds, mask, etc.) are 
also available for selection on the crosspoint matrix.
Thirty-two sources may be assigned at one time to the crosspoints 
— 16 unshifted and 16 shifted selections. During the installation 
procedure, each of the 32 input buses is assigned a video signal, a 
key signal, and a chroma key signal.
All inputs are defined by function, name, crosspoint, input 
number, and signal format.
You may determine the input assignments and the characteristics 
of the input signals through the use of the Configuration 
submenus, as described in the following procedures.
