1. Overview
1.1. This specification defines Projector control commands for LV-7225/7220/LV-5220.
1.2. The Projector control commands are for controlling Projector through RS232C from a computer.
2. Serial Interface Specification
2.1. Transfer Specification
Item Specification
Shynchro system Asynchronous
Transmission Speed 9600 / 19200
Data Length 8 bits
Parity None
Stop Bit 1
Flow Control None
1). Transfer rate: initial setting value is 19200.
2). Transfer rate can be changed by service mode.
2.2. Connection
Dedicated serial cable that comes with the projector must be used for a connection to a computer and
a Projector.

3. Notes for Communication
3.1. The Projector command is defined one command/one line that starts “C” and ends carriage return
(0x0D).
3.2. There are two types of command, functional execution commands and state read commands.
Example of Functional Execution Command
“C05” [CR]
Example of State Read Command
“CR0” [CR]
3.3. 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)
3.4. When a computer keeps sending some command; it must wait sending next command after 100ms
when the computer receives the return command.
More than 100ms
Command
PC → Projector “C” “0” “7” CR Next Command
Projector → PC ACK CR
Response
(A few ms- 5s)
3.4.1. When a computer sends next command before receiving a return command, the Projector may
not operate properly.
3.4.2. When there is no response after 5 seconds, issue next command.
3.5. It takes about 5 seconds for internal initialization after plugging in AC.
During this time, it cannot process command. Do not issue any commands.
3.6. Response for status read command after accepting has different characters.
See 7. Status Read Command.
3.7. Characters for commands must be capital (A - Z).
