LV-7585 Basic Serial Command Functional Specifications
1. Overview
・ These specifications define projector control commands for LV-7585.
・ The projector control commands are used to control a projector through RS-232C from a computer.
2. Serial Interface Specification
2.1. Transfer Specification
Item Specification
Synchronous system Asynchronous
Transmission Speed 9600 / 19200
Data Length 8 bits
Parity None
Stop Bit 1
Flow Control None
① Transmission speed: initial setting value is 19200.
② Transmission speed can be changed in service mode.
2.2. Connection
Dedicated serial cable that comes with the projector must be used for the connection between
computer and projector.
PC Projector
COM 1 Serial Port IN
(D-Sub 9Pin) (D-Sub 9Pin)
Connect COM port of the computer to SERIAL PORT IN of the projector.
COM Port (COM1 or COM2) of a computer is specified by control software of the computer.

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.
・ Do not send any subsequent command before reception of return value; however this is not the
case when no response is returned after more than 5 seconds.
・ It takes about 7 seconds for internal initialization after plugging in AC power. During this time, it
cannot process commands. Do not issue any command.
・ During 7 seconds after powering on in Standby mode, when the command for internal
initialization or lamp lighting is received, ACK value is returned but the function is not executed.
However, for Status Read Command, the function is executed in 500 ms after receiving ACK
value for POWER ON command.
・ During countdown and cooling operations:
During countdown operation after execution of power-on, as well as during cooling operation after
execution of power-off, ACK value is returned but the function is not executed when command is
received.
・ On switching INPUT:
During 5 seconds after switching action has started in response to reception of INPUT switching
command, ACK value is returned but the function is not executed when command is received.
However, for Status Read Command, the function is executed in 500 ms after receiving ACK
value for INPUT switching command.
・ The number of characters indicating successful reception of command varies according to the
command. Please see [7. Status Read Command].
・ Characters used for commands must be Capital (A - Z).
