PLV-HD2000 Basic Serial Command Functional Specifications

1 Overview

This specification defines projector control commands for PLV-HD2000.

・

The projector control commands are used to control a projector remotely through RS-232C from

・

a computer.

・

Refer to [8. Command with Address Specification] when using commands with address.

2 Serial Interface Specification

2.1

Transfer Specification

Items 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 cables that come with a projector must be used for the connection between a

computer and the projector.

PC Projector
COM 1 Serial Port IN

（D-Sub 9 Pin） （D-Sub 9 Pin）

Connect COM port of a computer to SERIAL PORT IN of the projector.

COM Port (COM1 or COM2) of a computer is specified by control software of the computer.

PLV-HD2000 Basic Serial Command Functional Specifications

3 Notes for Communication

・ The projector command is defined as a single command per line that starts with “C” and ends

with carriage return (0x0D).

・ When the projector receives carriage return, it starts decoding.

・ There are two types of commands: Functional Execution Commands and Status Read

Commands.

Example of Functional Execution Command: “C05” [CR]

Example of State Read Command: “CR0” [CR]

・ Projector clears the information of buffer in the cases below:

1) When the projector receives LF (0x0A) or EOF (0x1A).

2) When it takes more than one second to receive a signle command.

(Until the projector receives carriage return since it has received the first data.)

・ When executing the command pipelining for Functional Execution Commands, wait the interval

of time as below after the response.

1) [ZOOM UP/DOWN] [FOCUS UP/DOWN] [LENS SHIFT UP/ DOWN/ LEFT/ RIGHT]

Commands 100ms

2) Other Commands 500ms

・ When executing the command pipelining for Status Read Commands, allow at least 500ms after

the reception of the response.

・ Do not issue any command before receiving the response except when there is no response for

5 seconds.

・ Projector takes about 7 seconds for the internal initialization after plugging in AC until it moves to

Standby mode. During this time, the projector cannot process commands. Do not issue any

command.

・ For 7 seconds after executing Power ON operation in Stand-by mode, the projector receives a

command and returns the response but does not execute it due to the internal initialization or

lamp processing. However, Status Read Commands are carried out after 500ms when receiving

the response to Power ON command.

・ The operation during Countdown process and after Cooling Down:

When receiving a command during Countdown process after Power ON or Cooling Down

process after Power OFF, the projector returns the response but does not carry it out. However,

Status Read Commands are carried out.

・ The operation of Input switching:

Projector takes 5 seconds to switch inputs after receiving the command. When it receives

another command during this process, the command function is not executed. However, Status

Read Commands are carried out after 500ms since it receives the response to Input switching

command.

・ The number of characters of the response to Status Read Commands depends on commands.

・ Characters used for commands must be all Capital (A -Z).

6. Functional Execution Command Table

6.1 Format

・ PC issues a command in the format below:

“C” Command [CR]

Command: Two characters (Refer to Functional Execution Command Table)

・ A projector decodes the received data and returns the response when it gets ready to receive the

next command.

[ACK] [CR]: (0x06, 0x0D) When Functional Execution Command is received.
“?” [CR]: When the received data cannot be decoded.

6.2 When the Command Pipelining is needed

In the case of the function requiring command pipelining, the operation should follow the same way

as in remote control.

・ Sending-side system issues commands every 100ms.

・ When receiving an applicable command, the function is executed repeatedly for 120ms.

・ When receiving the same commands in sequence within 120ms, the function is repeatedly

executed for another 120ms from the moment of the second command reception.

・ When there is no incoming command after 120ms, the execution of pipelining is stopped.

・ When the projector receives the other command within 120ms, the execution of pipelining is

stopped.

6.4 Operation Requirements

When a projector is in the following status, available Functional Execution Commands are

limited. (in contrast Status Read Commands are valid even in these cases)

Projector Status Available Functional Execution Commands
