Control commands
IMPORTANT: When formatting commands sent from a control system or computer,
enclose commands in parentheses “(“ and “)”. When entering custom commands into
Scheduled Tasks in the projector’s web interface, enclose commands in less than/
greater than symbols “<” and “>” instead.
Serial Communication Configuration
Visit our website for additional RS-232 settings and information.
To control this projector via RS-232, connect a null modem cable and set the control
system serial port settings to match the following communication configuration:

RS-232 Port Settings

Setting Value
Bits per second 115,200
Data bits 8
Parity None
Stop bits 1
Flow control None
Emulation VT100
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 d o over the network. InFocus networ k
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:

Read Command Examples

Function Command Response
Brightness (BRT?) (0-100, 50)
Volume (VOL?) (0-100, 50)
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.
