Control commands
IMPORTANT: When formatting commands sent from a control system or computer, enclose 
commands in parentheses “(“ and “)”. 
Serial Communication Configuration

Network Communication Configuration
For network control, you can access the projector through Port 23 (Telnet).
We use the same control codes on serial as we do over the network. InFocus network control 
uses the Telnet packet structure.
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 
 
AAA denotes the command 
 
? denotes the read request
 
) ends the command
A read command returns the range and the current setting, for example
:

 (BRT?)

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 
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.
To assure the projector can process a command, wait 3 seconds before entering the next 
command.
