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.

RJ45 Adapter Cable Pin-outs
Most RJ-45 to DB9 adapters ship fully assembled, however, some are available only partially assembled,
allowing them to be customized if necessary. Additionally, some organizations may wish to build their own
adapters. The pin-outs below are provided to enable the completion of these adapters.
