Introduction

1.INTRODUCTION

This document defines the RS-232C command protocol for the Pioneer DVD-V7200 Industrial DVD Player.

The DVD-V7200 is capable of playing DVD, CD and VCD discs. The device has three control methods: front panel, remote control or computer interface through the RS-232C serial port.

This manual addresses the various commands and precautions required when using the player with a computer. Please refer to the DVD-V7200 Operating Instructions included in this bundle for details on operating the unit via the front panel and/or remote control.

Chapter 2 describes the Interface Connector Specifications and the Computer Control features of the DVD-V7200.

Chapter 3 discusses Baud Rate Settings, Interface Operation, Control Protocol, and Internal Operation via computer.

Chapter 4 explains the Player Command Structure in detail.

Chapter 5 reviews each command in detail.

Chapter 6 defines Address and Player Condition requests.

Chapter 7 relates to the various operating modes.

Chapter 8 discusses the internal registers.

Chapter 9 details the external switch control functions.

NOTE: In this manual, a DVD disc containing a modified program from a current educational Laser Disc (LD) is handled as a Laser BarCode (LB) compatible DVD disc. The disc has two formats: CAV and CLV.

Please be careful the following. The commands in this manual, it is not the same as LD players one. Both are exactly like but a little different in the detailed using.

CAUTION: The material in this manual is subject to change without notice.

PIONEER DVD-V7200 Industrial DVD Player RS-232 Command Protocol Manual

2.INTERFACE

2.1Interface Connector

A computer may be connected to the DVD-V7200 through either the RS-232 serial port or the parallel port by using a 15-pin D-Sub connector (e.g., a JAE DALCJ15SAF connector with suitable plug such as the JAE DA-15PF-N).

The pins are identified below:

2.2Serial Interface Pin Specification

Pin No.	Terminal	Input/Output	Function
1	GND	--	ground
2	TxD	Output	send data
3	RxD	Input	receive data
4	DTR	Output	enable data receiving
5	POWER	Output	external	power
			control
6	SW1	Input
7	SW2	Input
8	SW3	Input
9	SW4	Input
10	SW5	Input
11	SW6	Input
12	SW7	Input
13	SW8	Input
14	DLTST	INPUT	used only service support
			(do not make connection)
15	V +8V	OUTPUT	used only service support
			(do not make connection)

2.3Computer Control Functions

2.3.1Serial Control (see Chapters 3, 4, 5 and 6)

The player and computer are based upon the RS-232C protocol and are connected through the TxD, RxD, DTR and GND terminals.

-2 -

Computer Control

2.3.2External Switch Control (see Chapter 9)

Control the player with the External Option Switches (SW#).

Please make sure the Key Lock condition. If the player is in the Key Lock mode, the player ignores the control. (Please refer to the Key Lock command description.)

2.3.3External Power Control

Control the player’s power with the Power pin within the Interface Connector.

If the player detects a high signal throughput (100m/sec or more) during the Standby mode, the player powers on. If the player detects the same signal during the Power On mode, the player powers off and switches to the Standby mode.

The specifications for the Power pin are as follows:

Maximum Input		Less Than		μ 12V
Voltage
High Level Signal		More Than		4.5V
Low Level Signal		Less Than 0.5V
Standby mode				more than		Power On
				100 msec
Power On mode				more than		Power Off
				100 msec

Please make sure the Key Lock condition. If the player is in the Key Lock mode, the player ignores the control. (Please refer to the Key Lock command description.)

3.SERIAL CONTROL

3.1Serial Interface Specifications

3.1.1Signal Interface

The signal interface is an RS-232C connection.

3.1.2Data Type

Data Length: 8 bit

Stop Bit: 1 bit

Parity bit: No Parity

3.1.3Data Transfer Speed (Baud rate)

The data transfer speed can be set to either 4800 or 9600 baud on the Industrial player menu screen and/or with the Advanced Feature Menu Set command.(Please refer to the DVD-V7200 Operating Instructions and/or the Advanced Feature Menu Set command description.)

NOTE: The factory defaultis 4800 baud.The player memorizes the transfer speed every time and that is retained after the power cycle reaches completion.

3.2Communication with a Computer

The DVD-V7200 communicates to the computer through the player’s RS-232C port using pins 2 and 3 for communication and Pin 1 for grounding. Control or “handshaking” lines other than the TxD and RxD connections are not required. Please refer to the diagram below for clarification.

Computer		DVD-V7200
TxD		Pin 2 - RxD
RxD		Pin 3 - TxD
GND		Pin 1 - GND

In some computer, the CTS port should be set to HIGH during the communication. It is the best thing to connect the CTS of the computer to the DTR of the player. In normal operation and communication is available , the DTR in the player is set to HIGH thus the unit is able to receive a command at any time.

Computer Control

3.3Command and Status

The computer transmits a command to the DVD-V7200 and the player responds with the message, ‘execution complete’.

Example

COMPUTER			DVD-V7200
(1)	“Search to Frame 1000”	Þ	(2)	Search Execution
		Ü	(3)	Complete
(4)	“Play to Frame 2000”	Þ	(5)	Play Execution
		Ü	(6)	Complete

NOTE: The length of a command string is limited to 32 characters. Please refer to COMMAND STRUCTURE.

When using a computer to control the DVD-V7200 player, follow the command protocols listed below:

∙ASCII character codes are used for the actual commands and status response

∙Command mnemonic is expressed as two (2) ASCII characters

∙Uppercase letters are recommended; however, usually there are no distinctions between the use of uppercase or lowercase letters

∙Some commands require an argument, (e.g. chapter number or speed)

∙Use a command as the terminator of the argument

The player executes a command as soon as the carriage return <CR> is received. The <CR> acts as the command line terminator.

Example

CH<CR>

: Set chapter for address mode

10SE<CR> : Search to chapter 10

The player has a command buffer, which stores a command string of up to 32 characters in length.

Example

10SE 20PL<CR> : Search to chapter 10 then play to 20

The command string enters into the buffer with the left character and continues sequentially from left to right. When the <CR> is entered, the commands are executed sequentially beginning with the first command in the buffer. In the example above, the first command is 10SE.

NOTE: The player ignores codes in the command string such as <SPACE> or <LF> (line feed) which do not affect the player’s operation.

PIONEER DVD-V7200 Industrial DVD Player RS-232 Command Protocol Manual

NOTE: Some commands, sent after a specialty command which includes an AUTOSTOP setting, (PL, MF, MR, etc.), cause the player to execute the new command before the AUTOSTOP is enacted (see Chapter 5, Command Descriptions).

When all the commands in a string have finished executing, the player transmits or returns the "complete" message.

The player returns an R after a command has been executed. This response is called the Automatic Status. The Automatic Status signals the computer program to send the next command. If this function is not used, the command processing time must be taken into consideration before the next command is sent.

If an error occurs, the player returns an error message such as E04. The message indicates an error has occurred as well as the type of error. Error messages are in the form of EXX where XX represents a 2-digit error code.

In some cases, an incorrect command sends the player to search within a nonrecorded area and the player returns an error message. Use the Request Status function to determine the unit’s current status (actual player hardware failures are rare).

Apply one of the following methods to reset the player after an error has occurred:

∙Use ?P to determine the Active mode of the player

∙Use ?X, ?W, ?M, ?H, ?H ?S to determine the player information, model name, clock time, player region code, the setting of Industrial Player Menu, etc.

∙Use ?F, ?T, ?C, or ?R to determine the current frame, time, chapter, title/track number, respectively.

∙Use ?V, ?D, ?K, ?G, ?Y, or ?Q to determine the disc information, disc type, total frame number, TOC information, etc.

The status functions are summarized below:

Computer Control

3.4Error Messages

If an error occurs during a command execution, the player returns an error code. The table below lists each code with a description of the error:

Code	Message	Description
E00	Communication error	Communication Line Error due to framing error or
		buffer overflow
E04	Feature not available	Non-Usable Function has been tried – either the

Command Structure

NOTE: A command with an argument or address parameter is prefaced by arg (argument) or ards (address). If the arg or ards is in parentheses ( ), the parameter is optional.

4.1Command Mnemonic

Each command is expressed as two (2) ASCII alphabetic characters. There is no distinction between uppercase and lowercase letters except the Character strings in PR command.

NOTE: All command without Text File Data Upload (UU), Reject (RJ) and Open (OP) can not use while the video text is displayed on the screen. When any command without these are issued, the player returns the error code E04.

4.2Argument

An argument is expressed in either ASCII characters or ten digits and consists of either an address or an integer. A Control Register uses an integer value to set a specified value or condition.

If a command requires an argument, it is always placed before the command.

Example :	N1N2N3
	minimum 000 ~ maximum 300	(except MS command)
	Minimum 000 ~ maximum 520703	(Only MS command)

NOTE: If a command requires an argument but one is not supplied, the player returns an error message.

An Address can be a title, a chapter, a track, an index number, a frame number, or a time code depending upon how the address flag is set. The Address must not exceed the maximum allowed value of ten characters and/or digits.

	Address Type	Media Type	Format	Range (Min-Max)
	Title Number	DVD	N1N2	0 ~ 99
	Chapter Number	DVD	N1N2	0 ~ 99
	Frame Number	DVD/VCD	N1N2N3N4N5N6N7a	0 ~ 1079999
	Time Code	DVD	N1N2N3N4N5b	0 ~ 59959
		CD/VCD	N1N2N3N4c	0 ~ 9959
	Track Number	CD/VCD	N1N2	1 ~ 99
	Index Number	CD/VCD	N1N2	1 ~ 99
	Block Number	CD/VCD	N1N2N3N4N5N6d	0 ~ 995974

Command Structure

4.3Command String

A command string consists of multiple commands on one line. The maximum length of a command string is 32 characters. All command strings are terminated by the Carriage Return <CR> code (0DH hex).

Example : FR2000SE 2300PL<CR>

NOTE: The Real Time Clock Set (WW) , Print Character (PR), Blackboard/Stack Data Upload (BU), Blackboard/Stack Data Download (BD), Weekly Timer Data Upload (WU), Weekly Timer Data Download (WD), Text File Data Upload (UU) commands should be assigned individually.

Once the <CR> termination command is added to the string, the command string is evaluated and executed from left to right in sequential order.

If an error occurs during the execution of a command string, the remainder of the string following that command is not executed.

If a new command string is input before the execution of the current string is complete, the current string is aborted and the remaining commands are cleared.

To cancel a currently executing string, send the termination command <CR> alone.

If a new command without Text File Data Upload (UU) is input while the execution of the current command stack, the remaining of the current command stack are cleared.

4.4Status Returns

The completion message used in the Automatic Status is "R".

Example: R<CR>

4.5Error Message

An error message is indicated by the letter E and followed by a two-character error code.

Example: EN1N2<CR>

The error message occurs when the given command cannot be processed.

4.6Request Status Return

In response to a single request command, the status returns as a line of letters terminated by <CR>.

If multiple request commands are sent to the player within the same command string, the

-13 -

PIONEER DVD-V7200 Industrial DVD Player RS-232 Command Protocol Manual

player returns a separate status value upon completion of each command. A status value is a character string with a <CR> termination code.

Example: ?C?F<CR> Þ 02<CR> 10260<CR>

When the request command is at the end of the command string, the R within the completion message is omitted.

Example:	ST?F<CR>	Þ	23005<CR> (completion omitted)
Example:	?FST<CR>	Þ	23005<CR>R<CR> (not omitted)

4.7Timing

The time it takes to receive a command and return a Status Value is defined as follows:

T1 represents the time from when the termination of the command string <CR> is received to the beginning of the execution of the command extension. The maximum is approximately 24ms.

T2 represents the time it takes to execute the command. Depending upon the command type and the player’s condition, the minimum is 14ms.

Command Descriptions

If the player is in Random Access mode when the Play command is sent, the player enters Play mode and returns the completed status message. The Play mode is the only mode in which audio plays back simultaneously with video.

If an address is specified, an Auto Stop occurs on the selected sequence. The specified address is written as a Mark Frame or Mark Time and is compared with the current address. If the current address matches the specified address, the player enters Still mode and returns the completed status message.

The Auto Stop command is canceled if another command is sent before the player reaches the specified address. When this occurs, the player enters normal Play mode (the Stop Marker command is similar in function to Auto Stop).

If a Picture Stop code is detected before the player reaches the specified address, the player enters Still mode and returns an error message. However, if the disc program does not allow a stop, the player ignores the command and it may return the error message.

The available address modes are listed below:

	Address Mode	DVD	LB-compatible	CD	VCD
			DVD
	FR (frame)	X	X
	TM (time)	X	X	X	X
	CH (chapter)	X	X
	TI (title)	X	X
	BK (block)			X
	IX (index)			X	X
	TR (track)			X	X

Sometimes, an Auto Stop command within a VCD Block Number Address misses the specified address. Depending upon when the command is sent, a playback address may be missed by a maximum of ten-blocks.

Function	:	Playback occurs at the speed specified in the Speed Register
		(Option - Auto Stop)
Format	:	(Address)MF	(Multi-Speed Forward)
		(Address)MR	(Multi-Speed Reverse) (Address > 0)

Explanation : If the player is in Random Access mode when the command is executed, the player enters Multi-Speed mode and returns the completed status message immediately.

While in Multi-Speed mode, pictures are reproduced at the speed specified by the Speed Register. No audio tracks are played during Multi-Speed playback.

If an address is specified, an Auto Stop occurs on the selected sequence. The specified address is written as a Mark Frame or Mark Time and is compared with the current address. If the current address matches the specified address, the player enters Pause or Still mode and returns the completed status message. This command functions in a similar manner as the Stop Marker command.

If another command is issued before the player reaches the specified Address, the Auto Stop command is canceled and the player enters normal Multi-Speed mode. However, if the disc program does not allow a pause, the player ignores the command.

NOTE: There is no multi-speed reverse option without 1/2 speed in DVD. VCD offers 1/2 to 1/16 speed forward only.

Sometimes an Auto Stop command within some Multi-Speed commands misses the specific address. Depending upon when the command is sent, a playback address may be missed by a maximum of ten-blocks.
