Command Format
All commands consist of 3 alpha characters f
ollowed 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
AAA denotes the command
? denotes the read request
) ends the command
A read command returns the range and the current setting, for example
:
Read Command Examples
Function Command Response
Brightness (BRT?) (0-200, 100)
Lamp Hours (LMP?) (0-32766, 42)
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
maxim
um 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.
To assure the projector can process a command, wait 3 seconds before entering the next
c
ommand.
