Basic Serial Command Specification 1. Page 3 of 20 Overview 1.1. This Specification defines Projector control commands for LV-7565. 1.2. The Projector control commands are for controlling Projector through RS232C from a computer. 2. Serial Interface Specification 2.1.
Basic Serial Command Specification 3. Page 4 of 20 Notes for Communications 3.1. The projector command is defined one command/one line that starts “C” and ends carriage return (0x0D). 3.2. When a projector receives carriage return (0x0D), it starts decoding. 3.3. There are two type commands, functional execution commands and state read commands. Functional execution commands works as a remote control and key on the projector, and State read command works to know the projector status.

Basic Serial Command Specification 6. Page 6 of 20 Functional Execution Command 6.1. Format (1) PC sends a command as below format. “C” Command [CR] Command : 2 characters (See Functional Execution Command Table) (2) A projector changes receiving data to decode and send a return result after being ready to receive next command. [ACK] [CR] : (0x06, 0x0D) When a projector receives a functional execution command. “?” [CR] : When cannot read receiving data 6.2.

When Projector receives the appropriate command; it returns a character line as the required data. Required Data [CR] Required Data: a character line 7.1.3. 7.2. When receiving data cannot be decode, the Projector returns “?” [CR].
Basic Serial Command Specification 7.3.2. Page 18 of 20 “80” [CR] STAND BY When the status is STAND BY, Status Read Commands are always acceptable, but Functional Execution Commands are not acceptable except Power ON Command. 7.3.3. “40” [CR] Processing Count Down When “Display” in Setting Menu is ON and Power ON is executed, it starts processing Count Down. During this process, control commands except Power ON Command (“C00” [CR]) are unacceptable.
