. Creating the Serial Strings
The serial string to the projector can be comprised of ASCII characters,
hexadecimal bytes, relay control sequences and wait times embedded in
the strings. The length of each serial string must not exceed 250
characters. The current length of each string will be displayed in the String
Length box. In the Projector Commands drop down menu there are 10
options which are related to the string that would be sent when that
particular button is pressed. Select the Projector command you wish to
edit and then start typing the serial string into the Serial String text box.
1. Source = SRC1 On / Off
The On command will be issued when the Source 1 VGA/HD
input is selected via the VSA-31-SP‟s front panel button and the
button is illuminated. This command can tell the projector to
select the VGA input.
The Off command is issued when the Source 1 button is pressed
again. The button LED turns off, and Source 1 audio/video is
disconnected. (Microphone Volume is still active at this time)
2. Source = SRC2 On / Off, SRC3 On / Off
The Source 2 and Source 3 commands function in the same
manner as Source 1. Source 2 corresponds to the second
VGA/HD input, while source 3 is for Composite/S-Video input.
The VSA-31-SP converts the Composite video into S-Video so
the projector is always receiving S-Video when Source 3 is
selected. The serial command associated with this command will
tell the projector to select the S-Video input.
