LP1000 RS-232 Command Values

Communication Configuration

To control this projector from an RS-232 control system, connect the serial cable or a null modem cable and the InFocus

RS-232 Adapter (SP-CWRS232) and set the control system serial port settings to match the following communication

configuration*:

RS-232 Port Settings

Setting Value

Bits per second 19,200

Data bits 8

Parity None

Stop bits 1

Flow control None

Emulation VT100

LP1000, RS-232 Connection

The RS-232 connector on the LP1000 is amale DB9 connector. Use a null modem serial cable (9pin female -9pin

female) to connect between the RS-232 port and the serial port of the computer source. The connector scheme (from left

to right) is:

otop (pins 9,8,7,6): not used, not used, not used, not used

obottom (pins 5,4,3,2,1): ground, not used, send data, receive data, not used

Three pins need to be terminated: ground, send and receive (5, 3 and 2 respectively).

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.

Commands

The following table lists the RS-232 command value ranges for controlling the LP1000.

Note: Specified commands and values apply to the LP1000 with version 1.33 software or higher. The version number of

the software is the first number listed in the upper right corner of the on-screen menu. Command values for LP1000s with

earlier software versions may vary. If your LP1000 does not have version 1.33 software or higher, go to the

Software/Downloads page to download and upgrade the projector software.

0 = Off, 1-9999 = On for absolute command value ranges of 0 -1, unless otherwise noted.
