1.x of the projector. • Commands in this document are to communicate with LV-NI02, but most commands are used to control a projector remotely from a computer with RS-232C. Therefore commands in this document are defined as Expand Serial Commands. 2. Serial Interface Specification 2.1 Transfer Specification Item Specification Synchronous System Asynchronous Transmission Speed 9600 / 19200 Data Length 8 bits Parity N/A Stop Bit 1 Flow Control N/A Note1) Transmission Speed: initial setting value is 19200 Note2) Transmission Speed can be changed in Service mode. 2.2 Connection Dedicated serial cables that come with the projector must be used for the connection between a computer and a projector. PC Projector COM 1 Control Port (D-Sub 9Pin) (mini 8Pin) 9/71 LV-7575 Expand Serial Command Functional Specifications 3. Notes for communication • Expand Serial Command is defined as a single command per line that starts with “C” and ends with carriage return (0x0D). • There are two types of commands; Functional Execution Commands and Status Read Command. - Example of Functional Execution Command: “CF_BRIGHT_032” [CR] - Example of Status Read Command: “CR_BRIGHT” [CR] Note) “_” means a space • When it takes more than a second to receive a single command, it is not executed. When it takes more than a second to receive carriage return (0x0D) since the reception of the first data “C”, it clears the information of the receive buffer. • When the command pipelining, allow the interval time of no less than100ms after receiving return value. (No l ess than 100 ms) Command 1 1 1 PC ^ Projector “CF_BRIGHT_032” CR Next command Projector ^ PC “000” CR i Return Value 1 • i (A few ms - 5s) Do not send another command before the reception of the return value; the operation by the commond is not ensured. However this is not the case when no response is returned after more than 5 seconds. • It takes about 5 seconds for internal initialization after plugging in AC power. During this time, it cannot process commands. Do not issue any command. 4. Notation Convention • Data from a controller to a projector is represented as COMMAND, and data from a projector to a controller in response to the incoming command is represented as RESPONSE. • [CR]: Carriage Return Code Carriage Return code is added to the end of the command. Response is also followed by carriage return code. • _: Space Code Space Code is represented as (_). • %1: Parameter included in Command When there are more than one parameter, they are defined as %2, %3... • %%%: Error Code returned from a projector Acceptable: “000”. Unacceptable: See [7. Error Code Table]. 10/71 LV-7575 Expand Serial Command Functional Specifications 5.
