Control Software

You can use any one of a variety of available RS-232 programs to control a projector. Hyperterminal, for

example, comes with all versions of Microsoft Windows. Also consider Look RS232 (available at

www.lookrs232.com/). Some programs will allow you to assign RS-232 strings to hot keys or buttons.

Companies such as Crestron (www.crestron.com) and AMX (www.amx.com) make RS-232 control boxes

that make it easier to control your projector.

Command Format

All InFocus projectors use ASCII format command format. All commands consist of 3 alpha characters

followed by a request and all enclosed by 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 will report information to you, such as lamp hours. A write request is to tell the projector to

change a setting.

Command Examples

A read request example:

Command to request Brightness setting is (BRT?)

(starts the command

BRT denotes the brightness command

?denotes the read request

)ends the command

The response would appear as (0-22, 10), where

0-22 is the brightness range of the projector.

10 is the current brightness setting

Here are some other examples. To interpret the responses, you may need to refer to the actual list of

commands.

Function Command Response Description

Lamp Hours (LMP?) (0-32767, 250) 250 lamp hours

Aspect Ratio (ARZ?) (0-4, 1) 16:9 aspect ratio

Vertical Keystone (DKC?) (53-203, 60) Vertical keystone set to 60

A write request example:

Command to change Brightness setting to level 10 is (BRT10)

(starts the command

BRT denotes the brightness command

10 denotes the write request

)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.

Here are some other examples. Refer to the projector’s command list for other commands.

Function Command Response

Aspect Ratio (ARX2) Sets the aspect ratio to 4:3

Flip the image for

ceiling projection (CEL1) Enable ceiling projection

mode. Flips image.

Power up (PWR1) Powers up the projector.

Power down (PWR2) Powers the projector down.

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

command.

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.

Below is a list of common errors.

Function Command Response Reason

Aspect Ratio (ARZ2)A ? Too many characters

Flip the image (CEILING1) ? Too many characters.

Improper command.

Power Up (PWR99999) ? Invalid value. Too many 9s.

Most programs do not require a line feed after a command. Using a line feed, may cause the projector to

respond with a “?” indicating an invalid command. Commands should respond within seconds of entering

a command. If it does not, then there may issues with your connection, syntax or RS-232 software.

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.

Some commands may only be valid when the projector is receiving an active computer or video signal. If

a setting is not an active feature in the menu, the CLI command will not work. For example: aspect ratio,

color and tint are functions that require an active source.
