1. Overview

1-1. Introduction

The projector is remotely controllable over RS-232C as well as Ethernet. It is useful for setting up the projector away from the operator.

This protocol manual describes the specifi cations such as packet format and procedures for controlling the projector.

In the following sections below, the term “CONTROLLER” is used as a device which controls the projector. CONTROLLER can be a PC or other specifi c device that is able to handle RS-232C or Ethernet.

Although most of commands are available for both RS-232C and Ethernet, some commands are dedicated to Ethernet.

The software for controlling the projector from a PC is intended for performing transmission and reception for only the TxD and RxD lines.

Therefore the handshake normally performed by RS-232C is not necessary.

3-3-1. Outline of Communication

All communication between CONTROLLER (PC, etc.) and DEVICE (PROJECTOR) is performed by the command block format. Communication is started by the issue of a command at CONTROLLER and ended when the return data is sent to CONTROLLER after DEVICE receives the command.

CONTROLLER is prohibited from sending several commands at one time. This means that after CON-

TROLLER sends one command, it cannot send other commands until DEVICE returns the return data.

DEVICE sends the return data after processing the command. The time from when CONTROLLER sends the command until the return data is returned differs according to the contents of the command.

n

When SIRCS direct command is sent, return data is not sent.

. When sending a command from CONTROLLER, the return data from PROJECTOR should be received fi rst before sending the next command. Even if the next command is sent before receiving the return data, since PROJECTOR will not be able to receive that command, it does not return a response to

CONTROLLER. Consequently, no error code is also sent.

For detail of the waiting times for PROJECTOR to return the return data after CONTROLLER sends the command, refer to the section 3-5.

. When a communication error occurs, PROJECTOR ignores the data received until now, and set into the reception standby state.

. For undefi ned commands or commands determined as invalid by PROJECTOR, PROJECTOR will send the “NAK” as return data to CONTROLLER .

. Take note that when data is written with the unstable input signal of PROJECTOR, that data (value) will not be incorporated.

. When INDEX specifi ed SIRCS direct command is transmitted, leave an interval of 45 msec until the next transmission. (Do not return the return data (ACK, NAK) when the SIRCS direct command is received.)

. For POWER ON/OFF/TOGGLE of the SIRCS direct command, send the command twice when this unit is in standby mode (Low) state.

3-5. Approximate Return Waiting Times

The await-return time is approx. 30 to 1000 msec.

n

This is the case, unless the communications are interfered anyway.

4-1. Service

4-1-1. Advertisement

The advertisement service is provided to facilitate development of a PC application that can automatically detect a projector on the network. This function is achieved by broadcasting the equipment information periodically to the network.

This protocol is set to OFF by default.

Fig. 4-1 Command Sequence

It is prohibited that CONTROLLER send another command before receiving the response to the previous command. Since PROJECTOR executes the command before sending the return data, CONTROLLER must wait a while before receiving the response. The waiting time depends on not only the commands but also network traffi c.

There are two types of COMMAND fi eld, which are REQUEST and RESPONSE. REQUEST command is sent to the PROJECTOR from CONTROLLER. On the other hand, RESPONSE command is sent by

PROJECTOR as a response to the REQUEST command.

(1) REQUEST Command

COMMAND fi led for REQUEST has three sub fi elds shown as follows.

REQUEST(1) ITEM NO(2) DATA LENGTH(1)

Fig. 4-7 COMMAND Filed for REQUEST

There are only two types of request. One is the GET request to acquire the projector information and status. The other is the SET request to modify the projector setup.

SET (00h) Used to control turning the power on/off and to control the input selector, and to change the various setups.

GET (01h) Used to acquire the installation information, equipment status and various setup values.

2) ITEM NO sub fi eld

Refer to 6. of the section 4-3-2.

3) DATA LENGTH sub fi eld length is 128 bytes. If there is no data to be sent, its value should be 0h.

NG (00h) Indicates that the request is illegal or cannot be executed.

(1-1) OK Response

For SET Request, the packet format will be as follows.

OK[01h] ITEM NO(2) DATA LENGTH[00h]

If the response for SET Request is OK, DATA fi eld should be 00h. Therefore, DATA LENGTH fi eld should be 00h as well.

For Get Request, the packet format will be as follows.

OK[01h] ITEM NO(2) DATA LENGTH(2)

If the response for GET Request is OK, the DATA fi eld which follows the DATA LENGTH fi eld should be fi lled with returned data.

(1-2) NG Response

For SET/GET Request

NG[00h] ITEM NO(2) DATA LENGTH(2)

If the response for SET/GET Request is no good, DATA fi eld which follows the DATA LENGTH fi eld should be fi led with “ERROR CODE”. “ERROR CODE” are defi ned in 7. of the section 4-3-2.

2) ITEM NO sub fi eld

Refer to 6. of the section 4-3-2.

3) DATA LENGTH sub fi eld length is 128 bytes. If there is no data to be sent, its value should be 0h.

VPL-EW130

17

The content to be fi lled in this fi eld depends on the COMMAND fi eld. For SET Request commands, appropriate DATA value accompanied with ITEM NO should be chosen. ITEM NO (item number) and its data is shown in the section 2-1-1.

For the GET REQUEST and OK RESPONSE, this fi eld should not be provided. In that case, DATA

LENGTH should be 0h.

For setting the picture mode to dynamic, the packet should be as follows.

HEADER (VERSION, CATEGORY) = (02h, 0Ah)

COMMUNITY = “SONY” = (534F4E59h)

COMMAND (REQUEST, ITEM NO, DATA LENGTH) = (00h, 0002h, 02h)

DATA = 0000h

The same result can be obtained by using ENCAPSULATION mode as well.

HEADER (VERSION, CATEGORY) = (02h, 0Ah)

COMMUNITY = “SONY” = (534F4E59h)

COMMAND (REQUEST, ITEM NO, DATA LENGTH) = (00h, 7000h, 08h)

DATA (START CODE, ITEM NO, SET/GET, DATA, CHECK SUM, END CODE)

= (A9h, 0002h, 00h, 0000h, 02h, 9Ah)
