SIS command processing
When an AV switcher is connected to the RS-232 Pass Thru port, SIS commands are
processed in one of the following ways:
• Passed through to the AV switcher without being acted on by the SW USB
• Performed by the SW USB and not passed through to the AV switcher
• Performed by the SW USB and passed to the AV switcher, which also performs them.
This applies only to the input selection command X! !, where X! is the input number.
The table below shows how the SIS commands are handled by an SW USB with a
connected AV switcher. (Unless otherwise indicated, commands are not case-sensitive.)
