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.

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®-based control software. These operations are not available through the front panel of the SVS 100.

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-1and 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).

1. The first SIS command to the SVS 100 will recall a configuration preset:

1*30

In this example, preset #30 has been recalled for Input #1 of the SVS 100.

2. This SIS command to the Matrix switcher will switch its input to an output.
