PC COM 1 Projector SERVICE PORT 1 2 3 4 5 6 7 8 CD RXD TXD DTR SG DSR RTS CTS RING 1 2 3 4 5 6 7 8 9 (D-Sub 9 Pin) (Mini-DIN 8 Pin) Item Overview Page 4/18 SERIAL FUNCTIONAL SPECIFICATION 4. The projector command is defined one command/one line that starts "C" and ends carriage return (0x0D). 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. When a projector receives LF (0xoA) or EOF (0x1A) When it takes more than one second to receive on e command (Until the projector receives the carriage return after the projector receives the first data) 4. 5. When control command pipelining, after the response, wait interval of time as below. Wait at least 500 ms after the response, when status read command pipelining. Do not issue any command before the Response. When there is no response after 5 seconds, issue next command. If the projector receives other incoming commands within 120ms, the execution is stopped. 7. 3. Transfer Example Change to Video mode with Basic Command Command PC Projector Projector PC Processing (A few ms--1s) 7. 4.
