SERIAL FUNCTIONAL SPECIFICATION 1. Overview 1.1. This Specification defines projector control commands for LV-X4 (0.8”XGA model). 1.2. The projector control commands are for controlling projector through RS232C from a computer. 2. Interface Specification Item Shynchro system Transmission Speed Data Length Parity Stop Bit Flow Control Specification Asynchronous 9600 / 19200 8 bit None 1 None 1. Transfer rate: initial setting value is 19200 2. Transfer rate can be changed by service mode 3.
SERIAL FUNCTIONAL SPECIFICATION 4. Notes for Communication 4.1. The projector command is defined one command/one line that starts “C” and ends carriage return (0x0D). 4.2. The projector starts decoding after the carriage return. 4.3. There are two types of command, functional execution commands and state read commands. Example of Functional Execution Command: “C05” [CR] Example of State Read Command: “CR0” [CR] 4.4. It clears information of accepting buffer as following terms. 1.

SERIAL FUNCTIONAL SPECIFICATION 8. Status Read Command 8.1. Format 1. A PC issues commands fin format as below. “CR” COMMAND [CR] COMMAND: 1 character (See Status Read Command Table) 2. When a projector receives the appropriate command, it returns a character line as the required data. Required Data [CR] Required Data: A character line (See Status Read Command Table) 3. 8.2. When receiving data cannot be decode, the projector returns, “?” [CR].
SERIAL FUNCTIONAL SPECIFICATION 8.3.2. “80” [CR] Status: Standby When the status is Standby, Status Read Commands are always acceptable, but Functional Execution Commands are not acceptable except Power ON Command. 8.3.3. “40” [CR] Status: Processing Count down When “Display” in Setting Menu is ON and Power ON is executed, it starts processing Count Down. When “Display” OFF in the setting menu is set, processing Count Down is skipped and the status moves to Power ON quickly. 8.3.4.
SERIAL FUNCTIONAL SPECIFICATION 8.3.9. “02” [CR] Status: RS232C Command is unacceptable When a computer receives this response, try to execute Status Read Command again. 8.3.10. “24” [24] Status: Processing cooling down by power save When Power Management function is ON in setting menu and there is no signal for 5 minutes, it moves on to Power Save/Cooling Down after tuning off the lamps. (During this process, Green LED is OFF) The control command is invalid.
