Definitions
The following terms, which apply to Extron matrix switchers, are used throughout
this manual:
Tie — An input-to-output connection.
Set of ties — An input tied to two or more outputs. (An output can never be tied
to more than one input.)
Configuration — One or more ties or one or more sets of ties.
Current configuration — The configuration that is currently active in the
switcher (also called configuration 0)
Global memory preset — A configuration that has been stored. Up to 32 global
memory presets can be stored in memory. Preset locations are assigned to
the input buttons and output buttons. Up to 20 or 32 (depending on the
number of input and output buttons) presets can be selected from the front
panel for either saving or retrieving. When a preset is retrieved from
memory, it becomes the current configuration. All models have 32 presets;
on models with fewer than 32 input and output buttons, preset numbers that
are too high to be available from the front panel are accessible via serial port
control.
