RS-232 terminal specifications for IN74 and IN76Communication configurationTo 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 formatAll 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 commandAAA denotes the command? denotes the read request) ends the command
A read command returns the range and the current setting, for example
:
A write request example: (AAA####) where
( starts the commandAAA 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. If a command is received that is not 
understood, a “?” is returned. 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
