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 follow-

ing paragraphs, “CONTROLLER” means an external device such as a PC which controls projector using

these commands.

2. RS-232C

2-1. Communication Specifications

<RS-232C Communication Signal>

. Full duplex communication channels (Flow control not performed.)

. Start-stop synchronism system

. Baud rate: 38.4 kbps (bits per second)

. The bit configuration is defined as follows.

1 START Bit + 8 DATA Bits + 1 PARITY Bit + 1 STOP Bit

Q004-R1

2-4. Communication Procedure

2-4-1. 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.

When Sircs Direct Command is sent, return data may not be returned in some cases.

2-3. 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.

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 recep-

tion for only the TxD and RxD lines.

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

Q004-R1

2-5. Communication Rules

. When sending a command from CONTROLLER, the return data from PROJECTOR should be re-

ceived 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.)

2-6. Approximate Return Waiting Times

The await-return time is approx. 30 msec.

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

3. NETWORK

This section describes the performance, operations and protocol to be used of advertisement and PJ Talk.

3-1. 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.

3-3. SDAP Protocol

This section describes the SDAP packet structure.

Fig.1 Packet structure

1) Header

The header consists of ID (16 bit), version (8 bit) and category (8 bits).

Fig. 2 Header

It is fixed to “DA”.

Version

This indicates the version number of protocol.

It is fixed to 01h (version 1).

Category

Version 0.02

Use the following protocol to send data to and receive them from the projector.

The details on CMD1, CMD2, and DATA (written in red) are described in "Communication Commands".

The details on CHECK DATA, DATA LENGTH, and CHECK SUM (written in blue)

are described on this worksheet.

<About CHECK DATA

The total number of bytes from "DATA 1" to "DATA N" + 2 is assigned here.

s for the "DATA" part, the number of bytes vary depending the command to be sent.

lso, even when the command is the same, the number of bytes in the "DATA" section varies depending on whether the command is "SET" o

For this reason the value here varies depending on the command to be sent.

<About DATA LENGTH

The total number of bytes from "DATA 1" to "DATA N" + 2 is assigned here as in "CHECK DATA".

The difference from "CHECK DATA" is that only "the total number of bytes" is set without 2 added.

Sets the checksum.

Checksum can be calculated by

operating "XOR" to the values from "PERIHERAL INDEX(B1)" to "DATA N(Bm)".

ADJ SET command

Sets an adjustment value.

"ADJ REPLY data" returns when "ADJ SET" is executed.

(2) ADJ GET command

Acquires an adjustment value.

Response to the "Get adjustment value of ADJ item" command (ADJ REPLY data) returns when "ADJ GET" is executed.

(3) ADJ REPLY command

Response to the "Get adjustment value of ADJ item" command

(4) How to use the ADJ STATUS flag (ADJ REPLY: CMD[4])

(a) When the ADJ Status flag is "00h"

Since this is a normal adjustment value, set the adjustment item using the value of "ADJ DATA".

(b) When the ADJ Status flag is "01h"

Since this is an adjustment item error (the adjustment value of this item cannot be set), the adjustment item of Projector Station is masked

(displayed in gray).

Check that the value of "ADJ DATA" is "ADJ Lower" (the minimum value of the adjustment value) or larger and "ADJ Upper" (the maximum value of the adjustment value) or lower,

and set the adjustment item using the value of this "ADJ DATA".
