RS232 Terminal Specifications
Communication configuration
To control the projector from an LCD control panel or terminal 
software, connect a null modem type RS232 cable and set your 
computer ’s serial port settings to match this communication con-
figuration:
Here are the pinouts of the RS232 connector (outputs and inputs 
are relative to the projector):
Command format
All commands consist of 3 alpha characters followed by a 
request, all enclosed in parentheses. 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

Appendix
A read command returns the range and the current setting, for 
example:
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
NOTE: To assure the projector
can process a command, wait 3
seconds before entering the next
command.
Some commands have ranges, while others are absolute. If a 
number greater than the maximum range is received, it is auto-
matically set to the maximum number for that function. If a com-
mand is received that is not understood, a “?” is returned. With 
absolute settings, “0” is off, 1-2147483647 is on. The one exception 
is the Power command, where 0 is off and 1 is on.
