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)
