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 example:
(AAA?) where (starts the command
AAAdenotes 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 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. If a command is received that is not understood, a "?" is returned. With absolute settings, "0" is off,
To assure the projector can process a command, wait 3 seconds before entering the next command.
