Definitions
The following terms 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 multiple
inputs.)
Configuration — One or more ties or sets of ties.
Current configuration — The currently active
configuration (also called configuration 0).
Preset — A configuration that has been stored. One
preset can be assigned to each input and output
button. Additional presets are available under
RS-232/422 control. When a preset is retrieved, it
becomes the current configuration.
Front Panel Controls
Input and output buttons select and identify
inputs and outputs. The buttons also select
presets.
Enter button saves changes when you change the
configuration.
Preset button saves a configuration as a preset or
recalls a previously-defined preset.
Input and output buttons can hold text or icon
inserts that can be created easily with Extron’s
label software.
LCD Displays
To view the current configuration, press and release
the button for the desired input. The LCD displays
the input number for approximately 1 second and
then the current configuration for approximately
10 seconds. The LCD displays each output number
on the top line and the tied inputs on the bottom
line. To check the status of another source, press
and release another Input button.
