    RS-232 terminal specifications for IN74/IN76/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 th is communication configuration:Command formatAll commands consist of 3 alpha char acters followed by a request, all 
    enclosed in parentheses. The request ca n 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 exam ple: (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 rece ived, it is automatically set to the 
    maximum number for that function. If a command is received that is not 
    understood, a “?” is re turned. With absolute settin gs, “0” is off, 1-9999 is on. 
    The one exception is the Power command, where 0 is off and 1 is on
    .
