Note on video signals that go to the Projector

When you select either of the 2 VGA inputs (Source 1 or Source 2), the VGA
output to the projector has the selected signal and the S-Video output is blanked
out. Conversely, if the input is Composite Video or S-Video (Source 3), only the
S-Video output to the projector will have a signal. This means that it is possible to
use the projector’s auto-detect mode to switch between video inputs and not even
connect the serial port to the projector. However in doing so, you will not be able
to use the on/off button on the sender to control the projector, and you will still
have to rely on the projector’s remote control to turn the projector on and off.

Prior to final installation of the user interface and connector panel wall plates, you
need to use the supplied Windows™ software and the serial cable to program the
serial codes needed to operate the projector into the sender wallplate.
