DOWNFRAMING
If more than 16 video outputs are required, multiple matrix bays must be installed in a downframe configuration. Downframing allows the video
inputs of one bay to be connected to the video inputs of one or more additional bays, providing an additional 16 video outputs for each additional
bay that is downframed. The inputs in the first bay become available to the downframed bays and any video input can be switched to the
additional 16 monitor outputs provided in each downframed bay. A maximum of eight matrix bays can be connected in a downframe configura-
tion, providing a maximum of 128 video outputs.
As viewed from the rear of the matrix bays, Figure 57 illustrates a sample downframe configuration containing a total of 256 video inputs and
32 video outputs. The downframe configuration illustrates downframing to one bay.
