Saving and Recalling Input Configuration Presets

The SVS 100 is capable of storing up to 128 input configurations which can be
recalled just prior to switching from one input to another. This save/recall
capability is only available through RS-232/RS-422 commands and not via the front
panel controls of the SVS 100. By recalling preset input configurations just prior to
switching, switching from one input to another can be accomplished in a seamless,
well-planned fashion. See chapter 5, Serial Communication, for details on saving
and recalling memory presets.
The input configurations that can be stored include all the Picture Control
functions, such as color, tint, brightness, contrast, top blanking. The Effects
settings, such as effect, transition, and duration, the audio level, and the Genlock
Controls, such as horizontal phase and sub phase, are not saved. Figure A-1 and
the following Simple Instruction Set commands illustrate how the SVS 100 can
recall a configuration preset for input from an Extron 32 x 32 Matrix 3200 video
switcher.
Figure A-1 — Configuration preset application example
The following sequence of SVS 100 RS-232 commands will recall an SVS 100
preset configuration, send a command to the Matrix switcher which tells the
Matrix switcher where to output an input signal, and finally, send a command to
tell the SVS 100 to switch to the next input (which is now configured with the
recalled preset configuration).

SVS 100 Appendix
Saving and recalling preset input configurations are only available through
RS-232/RS-422 control using the Simple Instruction Set commands or by
using the included Windows
available through the front panel of the SVS 100.
