. 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-32’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-32 up-scales 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.
