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.
