[. . . ] 26 4/26 LV-7500 Basic Serial Command Functional Specifications 1. Overview ・ ・ These specifications define projector control commands for LV-7500. The projector control commands are used to control a projector through RS-232C from a computer. 2. Transfer Specification Item Synchronous system Transmission Speed Data Length Parity Stop Bit Flow Control ① Specification Asynchronous 9600 / 19200 8 bits None 1 None Transmission speed: initial setting value is 19200. ② Transmission speed can be changed in service mode. Connection Dedicated serial cable that comes with the projector must be used for the connection between computer and projector. PC COM 1 Projector Control Port （D-Sub 9 Pin） （Mini 8 Pin） 5/26 LV-7500 Basic Serial Command Functional Specifications 3. Notes for Communication ・ The projector command is defined as one command per line that starts with “C” and ends with carriage return (0x0D). ・ ・ When carriage return (0x0D) is received, decoding starts. There are two types of commands; Functional Execution Commands which function in a way comparable to remote and console keys and Status Read Commands which get basic statuses of projector. Example of Functional Execution Command: “C05” [CR] Example of Status Read Command: “CR0” [CR] ・ In the cases below, it clears information of receive buffer. 1) When LF (0x0A) and EOF (0x1A) are received 2) When it takes more than a second to receive one command (until the projector receives carriage return since it has received the first data) ・ or the pipelining of Functional Execution Command, allow the following interval time after receiving return value. 1) Commands “VOLUME +/-“, “ZOOM UP/DOWN”, “FOCUS UP/DOWN” and “LENS-SHIFT UP/DOWN/RIGHT” --> 100ms 2) Other commands --> 500ms ・ For the pipelining of Status Read Command, allow more than 500 ms of interval time after reception of return value. When Input 2 has been selected, this command does not execute the source switching; just for switching to Input 2. Acceptable Unacceptable [ACK] [CR] “?” [CR] Response 6. 10 Command Detail INPUT 3 Command “C07” [CR] Select Input 3. This command works differently from the command by “Input 3” key of the remote control. When Input 3 has been selected, this command does not execute the source switching; just for switching to Input 3. Acceptable Unacceptable [ACK] [CR] “?” [CR] Response 6. 11 Command Detail Response NETWORK Command “C08” [CR] Select Network Input Acceptable Unacceptable [ACK] [CR] “?” [CR] 6. 12 Command Detail VOLUME + Command “C09” [CR] Volume Up This command works the same way as “VOLUME +” button of the projector and remote control. Acceptable Unacceptable [ACK] [CR] “?” [CR] Response 6. 13 Command Detail VOLUME – Command “C0A” [CR] Volume Down This command works the same way as “VOLUME -” button of the projector and remote control. Acceptable Unacceptable [ACK] [CR] “?” [CR] Response 12/26 LV-7500 Basic Serial Command Functional Specifications 6. 14 Command Detail SOUND MUTE ON Command “C0B” [CR] Sound Mute ON This command works the same way as “MUTE” button of the remote control for Mute ON, but does not work for Mute OFF. Acceptable Unacceptable [ACK] [CR] “?” [CR] Response 6. 15 Command Detail SOUND MUTE OFF Command “C0C” [CR] Sound Mute OFF This command works the same way as “MUTE” button of the remote control for Mute OFF, but does not work for Mute ON. Acceptable Unacceptable [ACK] [CR] “?” [CR] Response 6. 16 Command Detail VIDEO MUTE ON Command “C0D” [CR] Video Mute ON This command works the same way as “NO SHOW” button of the remote control for No Show ON, but does not work for No Show OFF. Acceptable Unacceptable [ACK] [CR] “?” [CR] Response 6. 17 Command Detail VIDEO MUTE OFF Command “C0E” [CR] Video Mute OFF This command works the same way as “NO SHOW” button of remote control for No Show OFF, but does not work for No Show ON. Acceptable Unacceptable [ACK] [CR] “?” [CR] Response 6. 18 Command Detail Response SCREEN NORMAL SIZE Command “C0F” [CR] Set screen size to Normal (4:3) Acceptable Unacceptable [ACK] [CR] “?” [CR] 6. 19 Command Detail Response SCREEN WIDE SIZE Command “C10” [CR] Set screen size to Wide (16:9) Acceptable Unacceptable [ACK] [CR] “?” [CR] 13/26 LV-7500 Basic Serial Command Functional Specifications 6. 20 Command Detail Response MENU ON Command “C1C” [CR] Display On-Screen Display Menu Acceptable Unacceptable [ACK] [CR] “?” [CR] 6. 21 Command Detail Response MENU OFF Command “C1D” [CR] Clear On-Screen Display Menu Acceptable Unacceptable [ACK] [CR] “?” [CR] 6. 22 Command Detail Response DISPLAY CLEAR Command “C1E” [CR] Clear On-Screen Display Clear On-screen Display under all conditions Acceptable Unacceptable [ACK] [CR] “?” [CR] 6. 23 Command Detail Response BRIGHTNESS + Command “C20” [CR] Increment Brightness by 1 according to user control. [. . . ] Even if the temperature goes down during this process, the given Cooling Down process is conducted. ・ “88” [CR] Status: Standby after Cooling Down due to Abnormal Temperature When the status becomes Standby after the temperature goes down by Cooling Down operation invoked due to Abnormal Temperature, the projector returns “88” [CR]. This indicates Abnormal Temperature caused turning to Standby status. This status continues until the next operation is started; when Power On is executed, the 23/26 LV-7500 Basic Serial Command Functional Specifications projector clears the information of Abnormal Temperature and normal operation starts. ・ “24” [CR] Status: Power-Save Cooling Down in process This indicates Power Management in the Setting menu is enabled and Power-Save Cooling Down operation is in process. During this time, any Functional Execution Command is invalid. [. . . ]
