RS-232 terminal Product Interface specifications
Communication configuration
To control the projector from an LCD control panel, connect an RS-232 cable to
the serial control connector on the projector and set your computer’s serial port
settings to match this communication configuration:
Command format
All commands consist of 3 alpha characters followed by a request, all enclosed in
“greater than” and “less than” signs. The request can be a read request (indicated
by a “?”) or a write request (indicated by 1 to 4 ASCII digits).
A read request format: <AAA?> where
< starts the command
AAA denotes the command
? denotes the read request
> ends the command
A write request example: <AAA=####> where
< starts the command
AAA denotes the command
=#### denotes the value to be written
(leading zeros not necessary)
> ends the command
Some commands have ranges, while others are absolute. If a number greater than
the maximum range is received, it is automatically set to the maximum number for
that function. With absolute settings, “0” is off, 1-9999 is on. The one exception is
the Power command, where 0 is off and 1 is on .

uct Interface formats.
