Notes for Communication 4.1. The projector command is defined one command/one line that starts "C" and ends carriage return (0x0D). 4.2. 4.3. The projector starts decoding after the carriage return. 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) 2) When a projector receives LF0xoA or EOF0x1A 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. 1) 2) COMMAND such as "VOLUME +/-" ! 100ms Other COMMAND ! 500ms 4.6. Wait at least 500 ms after the response, when status read command pipelining. 4.7. Do not issue any command before the Response. When there is no response after 5 seconds, issue next command. 4.8. It takes about 7 seconds for internal initialization after plugging in AC. cannot process command. Do not issue any commands. 4.9. 7 seconds after StandBy or Power ON, even when a projector receives a command, a computer receives acceptable response, but it does not execute for internal initialization and lamp lighting process. However, Status Read Commands are executed after 500ms when they receive acceptable response. 4.10. About performance during processing count down or cooling down. When a projector receives After Stand By or Power ON, Even when a projector receives a command, a computer receives response to accept the command, but it does not execute for internal initialization and lamp lighting process. executed. 4.11. About performance when changing INPUT. After receiving INPUT switching command, when receiving commands between 5 seconds from starting the switching to completing the switching, a computer receives acceptable command, but it is not executed. However, status read commands are executed after a computer receives response to accept the command, after 500ms. 4.12. Response for Status Read Command after accepting has different characters. See "Status Read Command Table". 4.13. Characters for commands must be Capital (A - Z). However, Status Read Commands are During this time, it SERIAL FUNCTIONAL SPECIFICATION Page 5 of 18 5.

Functional Execution Command 7.1. Format "C" COMMAND [CR] 1) PC issues a command as below form at 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]:0x06,0x0DWhen received functional execution commands. "?" [CR]: When cannot read received data 7.2. When the command pipelining is needed When some functions need command pipelining , the performance is the same as the remote control's performance. 1) System: issue any commands every 100ms after receiving response 2) When receiving the same command continuously with 120ms, the function is executed for 120ms from that moment. 3) When receiving the same command continuously, with 120ms, the function is executed for 120ms form the moment. 4) 5) The next command is not issued after 120ms, and the execution is stopped.
