1. Overview 1.1 This Specification defines projector control commands for LV-S3 (0.5”SVGA model). 1.2 The projector control commands are for controlling projector through RS232C from a computer. 2. Interface Specification Specification Shynchro system Asynchronous Transmission Speed 9600 / 19200 Data Length 8 bit Parity None Stop Bit 1 Flow Control None 1. Transfer rate: initial setting value is 19200 2. Transfer rate can be changed by service mode 3.
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. 4.4.1 When a projector receives LF（0xoA） or EOF（0x1A） 4.4.
4.12 Characters for commands must be Capital (A - Z). 5.

. Functional Execution Command Table 7.1 Format 1. PC issues a command as below form at “C” COMMAND [CR] Command: 2 characters (See Functional Execution Command Table) 2. A projector decodes received data and sends a return result after being ready to receive next command. [ACK] [CR]:（0x06,0x0D）When received functional execution commands. “?” [CR]: When cannot read received data 7.
7.4 Operation Requirements When the projector’s status in this below, functional execution commands are limited. Status Read Commands are available even in this table status.

8.2 Transfer Example Get input mode for the projector by basic commands. COMMAND（(current input mode command issue)） PC Æ Projector “C” ”R” ”1” CR Projector Æ PC ”1” ←―――→ CR Response (A few ms--1s) (Shows Computer 1 is selected) 8.
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. This Count Down finishes in 60 seconds and moves to Power ON. During this process, control commands except Power ON Command (“CC00”)[CR]) are unacceptable. When Power ON Command is executed, processing Count Down is terminated and the status moves to Power ON.
8.3.8 “88” [CR] Status: Normal status after recovering abnormal temperature. When the temperature goes down after cooling down and moving to Standby status, this is the response. This status keeps until the next operation. In short, when Power On is executed, the temperature information is canceled, and works normal. 8.3.9 “02” [CR] RS232C Command is unacceptable. When a computer receives this response, try to execute Status Read Command again. 8.3.
