InFocus LP260 Instruction manual
LP260 RS-232 Connection
The LP260 requires the serial control cable (part # 210-0203-xx) that comes with the projector.
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?) (0-22, 10)
Volume (VOL?) (0-80, 0)
Lamp Hours (LMP?) (0-9999, 421)
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.
Write Command Examples
Function Command Response
Brightness (BRT10) Sets the brightness
to 10
Freeze (FRZ1) or
(FRZ8888) Freezes the display
Power (PWR0) Turns power off
Power (PWR1) Turns power on
Error Conditions
Not all commands are supported for all projectors. If an unsupported command is issued, the command will be ignored. If a
command is received that is not understood, a ‘?’ character will be returned indicating the command was not understood.
Limitations
The CLI cannot respond to commands coming in at a high-rate. Therefore, a delay must occur between commands to ensure that
the command gets properly executed. To assure the projector can process a command, wait 3 seconds before entering the next
command.
LP260 RS-232/CLI Values
The following table lists the RS-232 command value ranges for controlling the LP260 projector.
