Selecting Inputs Using Delimiters
When selecting inputs to the projector, or display (Dsp) and/or the System 4xi switcher (Sw), audio and video can be switched together (follow) or separately (breakaway). An input is selected by its ASCII number, followed by a delimiter character. The delimiter ends the command and also determines which inputs (audio/video) are affected. System 4xi delimiters are listed and explained below. There are four delimiters that affect the
System 4xi. They are:
!Affects Audio & Video (Aud/Vid) for the switcher (Sw) and affects only video for the projector (Dsp/Sw) @ Affects Audio and Video (Aud/Vid) for switcher only (Sw)
$ Affects Audio only (Aud) for the switcher (Sw)
&Affects Video only (Vid) for both projector and switcher (Dsp/Sw)
