Applications of the RS232/RS422 connection
Remote control:
• easy adjustment of projector via IBM PC (or compatible) or MAC connection.
• address range : 0 and 1.
• allow storage of multiple projector configurations and set ups.
• wide range of control possibilities.
Data communication: sending data to the projector or copying the data from the projector to the computer.
To set up the baud rate of the projector, see "Baudrate setup", page 74.

Trigger outputs
Aspect ratio
When the internal projector aspect ratio is switched to 4 by 3 or 5 by 4 a 12 V DC voltage will set on the Aspect Ratio output. In all
other cases the is no voltage available on that output.
This 12 V voltage can be used to trigger e.g. the curtains next to the screen when switching from wide image to a small image.
Screen
When the projector is in operational mode, a 12 V DC voltage is set on the Screen output. When the projector is in standby, there
is no voltage at the output.
This 12 V voltage can be used to trigger e.g. a motor which rolls out the screen when starting up the projector.
