InFocus LP1000 Configurations

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 a male 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: o top (pins 9,8,7,6): not used, not used, not used, not used o bottom (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

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.

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.
