Overview This Specification defines Projector control commands for LV-7565. The Projector control commands are for controlling Projector through RS232C from a computer. 1.1. 1.2. 2.

Notes for Communications The projector command is defined one command/one line that starts "C" and ends carriage return (0x0D). 3.1. 3.2. 3.3. When a projector receives carriage return (0x0D), it starts decoding. 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. Example of Functional Execution Command : "C05" [CR] Example of State Read Command : "CR0" [CR] 3.4. When it takes more than one second to receive on command, it clears information of buffer. (Until the projector receives the carriage return since the projector has received the first data) 3.5. When control command pipelining, after the response, wait interval of time as below. 3.5.1. [VOLUME + / -] [ZOOM UP / DOWN] [FOCUS UP / DOWN] [LENS-SHIF UP / DOWN / LEFT / RIGHT] Commands ! 100ms 3.5.2. Other Commands ! 500ms 3.6. 3.7. Wait at least 500ms after the response, when status read command pipelining. Do not issue command before the Response in the situation as below, except no response after 5 seconds. 3.8. It takes about 7 seconds for internal initialization after plugging in AC. During this time, it cannot process command. Do not issue any commands. 3.9. 7 seconds after Stand By 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. 3.10. 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. However, Status Read Commands are executed after 500ms when a computer receives acceptable response. When a projector receives a command while processing count down after Power ON or cooling down after Power Off, a computer receives response to accept the command but the command is not executed. However, Status Read Commands are executed. 3.11. 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. 3.12. Response command characters for status read success are different. See "7, State Read Command" for the details. 3.13. Command are shown in a capital letter (A Z). Lower case letters are not available. Basic Serial Command Specification Page 5 of 20 4.
