1. Introduction

This protocol manual describes the basic configuration and basic operations of various commands used for projector. Projector can be controlled using the commands provided in “Appendix”. Using an external CONTROLLER , etc., inputs can be switched and the power can also be turned on and off. In the following paragraphs, “CONTROLLER” means an external device such as a PC which controls projector using these commands.

2-4. Connection

<RS-232C Connection>

Communication is enabled by the use of a D-Sub 9 Pin cross (reverse) cable.

The pin assignment of D-Sub 9 Pin and D-Sub 25 Pin is as follows.

D-Sub 9 Pin	D-Sub 25 Pin		Name
Shell = FG	1	FG	Grounding for safety protection or cable shield
3	2	TxD	Transmission data
2	3	RxD	Reception data
7	4	RTS	Transmission request
8	5	CTS	Transmission permission
6	6	DSR	Data set ready
5	7	SG	GND for signal
1	8	DCD	Data channel signal carrier detection
4	20	DTR	Data terminal ready
9	22	RI	Calling display (Presence/absence of calling signal)

Pins indicated as D-Sub 25 Pin are not used.

Assured cable length: 15 m (However, assurance may not be applicable for some cables.)

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

Therefore there is no handshake normally performed by RS-232C.

2-5. Communication Procedure

2-5-1. 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 CONTROLLER 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 may not be returned in some cases.

4	VPL-CX75/CX76/CX85/CX86/FX51/FX52/FX52L/PX35/PX40/PX41

2-6. Communication Rules

.When sending a command from CONTROLLER, the return Data from PROJECTOR should be received first 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.

The following lists the approximate waiting times for PROJECTOR to return the return Data after CONTROLLER sends the command.

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

.For undefined commands or commends determined as invalid by PROJECTOR, PROJECTOR will send the “NAK” return Data to CONTROLLER .

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

.When INDEX specified 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.)

2-7. Approximate Return Waiting Times

The await-return time is approx. 30 msec.

n

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

3-1-2. Remote Control

The remote control service is provided that can control the target equipment from remote location via network. The SDCP protocol that serves to acquire the basic information such as equipment name and serial numbers is installed in this projector.

3-1-2-1. Function

This responds to the control command and requests for acquiring the status and information supplied from clients.

Control request

Enables the input to be selected and picture control to be adjusted.

SIRCS request

Enables remote control by sending the SIRCS code.

Status request

Enables equipment status information such as power status, error information and power-on time to be acquired.

Information request

Enables equipment information such as equipment name, serial number and installation information to be acquired.

Protocol

Item	Description
Protocol name	SDCP (Simple Display Control Protocol)
Transport	TCP
Port number	53484
TCP connection timeout	30 seconds
