2. INTERFACE

2.1 Interface Connector

A computer may be connected to the DVD-V5000 using a 15-pin D-Sub connector (e.g., a JAE DALC-J15SAF connector with suitable plug such as the JAE DA-15PF-N) to the RS-232C serial port or to the parallel port.

This unit is also equipped with 9pin connector for serial control. In advanced setup user can choose which port to be used for serial control depends on the cable availability. Either 9pin cross cable or conventional 15pin cable (same cable to be used with DVD-V7400). The factory default setup is 15pin.

The pins are identified below:

2.3 Computer Control Functions

2.3.1 Serial 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.

2.3.2 Extend Terminal Control (see Chapter 9)

Control the player with the Extend Terminal Switches (SW#). Even if the Key Lock is set (active), the extend terminal control is

available.

2.3.3 External 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 Voltage Less Than 12V High Level Signal More Than 4.5V Low Level Signal Less Than 0.5V

Standby mode

more than

100 msec Power ON

3. SERIAL CONTROL

3.1 Serial Interface Specifications

3.1.1 Signal Interface

The signal interface is a standard RS-232C connection.

3.1.2 Data Type

Data Length: 8 bit Stop Bit: 1 bit Parity bit: No Parity

3.1.3 Data Transfer Speed (Baud Rate)

The data transfer speed may be set to either 19200 or 9600 baud through the Advanced Setup Menu screen or with the Advanced Feature Menu Set command (refer to the DVD-V5000 Operating Instructions for command description).

NOTE: The factory default is 19200 baud; however, the player memorizes the transfer speed each time the power is cycled.

RS-232 Command Protocol

3.2 Communication with a Computer

The DVD-V5000 communicates to the computer through the RS-232C port using pins 2 and 3 for communication and Pin 1 for grounding in case of using 15-pin D-sub connector or Pin 5 for grounding when using 9-pin D-sub connector. Control or “handshaking” lines other than the TxD and RxD connections are not required. Please refer to the diagram below for clarification.

Computer DVD-V5000

TxD

RxD

GND

Some computers require the CTS port to be set to HIGH during communication. It is best to connect the CTS and DSR port on the computer to the DTR port on the player. During normal operation the player’s DTR is set to HIGH thus the unit is able to receive a command at any time.

RS-232 Command Protocol

3.3 Command and Status

During normal operation, when a computer transmits commands to a DVDV5000, the player responds with the status message, ‘execution complete’.

Example

COMPUTER DVD-V5000 (1) “Search to Frame 1000” ⇒ (2) Search Execution ⇐ (3) Complete

(4) “Play to Frame 2000” ⇒ (5) Play Execution ⇐ (6) Complete

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

When using a computer to control the DVD-V5000 player, follow the command protocols listed below:

• ASCII characters are used for 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 uppercase and lowercase letters

• Some commands require an argument (e.g. Chapter number or speed)

• Use a command as the terminator of an 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 the buffer with the first 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.

DVD-V5000 DVD Player

RS-232 Command Protocol

NOTE: The player ignores codes in the command string such as <SPACE> or <LF> (line feed) that have no affect on the player.

NOTE: Some commands, sent after a specialty command that 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 that is represented by the capital letter R.

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 current status (actual player hardware failures are rare).

• ?P to determine the Active mode of the player

• ?X, ?M, ?H, ?S to determine the player information, model name, player

region code, the setting of Advanced Setup Menu, etc.

• ?F, ?T, ?C, or ?R to determine the current Frame, Time, Chapter, Title/Track number, respectively.

• ?V, ?K, ?G, ?Y, or ?Q to determine the disc information, disc type, total Frame number, TOC information, etc.

The status functions are summarized below:

DVD-V5000 DVD Player

RS-232 Command Protocol

4.1 Command Mnemonic

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

4.2 Argument

An Argument, expressed in either ASCII characters or ten digits, 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 :

Minimum 000 ~ Maximum 2047 (Only MS command)

Minimum 000 ~ Maximum 300 (except 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, a Frame Number, or a Time Code depending upon how the address flag is set. The Address must not exceed ten characters and/or digits.

N1N2N

Address Type Media Type Format Range (Min-Max)

Title Number DVD N1N2 1 ~ 99 Chapter Number DVD N1N2 1 ~ 99 Frame Number DVD N1N2N3N4N5N6 1 ~ 999999

Time Code Track Number CD/VCD N1N2 1 ~ 99

Block Number CD N1N2N3N4N5N

4.3 Command 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: Assign the following commands individually.

• Print Character [PR]

DVD-V5000 DVD Player

RS-232 Command Protocol

• Stack Data Upload [BU]

• Stack Data Download [BD]

• Memory Data Upload [MU]

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

If an error occurs during the execution of a String, the remainder of the string following that command is ignored.

If a new command string is input before the current string executes completely, the current string is aborted and the remaining commands are cleared.

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

If a new command without [?*], [#*] or [$*] is input while playing the current command stack, the remaining commands are cleared.

The DVD-V5000 does not accept other commands during the execution of a Search command, returning an E04 error message. After issuing a Search command, wait until the Return (R) status appears before issuing another command. An exception to this rule is the Mark Frame Play command (i.e. FR1200PL), when it is unnecessary to wait for the R status before sending additional commands.

4.4 Status Returns

The completion message used in the Automatic Status is R.

Example: R<CR>

4.5 Error Message

An error message consists of an E followed by a two-character error code.

Example: EN

1N2

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

4.6 Request Status Return

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

<CR>

4.7 Timing

Example:

RxD

TxD

DVD-V5000 DVD Player

RS-232 Command Protocol

If multiple commands are sent within the same String, the 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> ⇒ 02<CR> 10260<CR>

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

Example: ST?F<CR> ⇒ 23005<CR> (completion omitted)

Example: ?FST<CR> ⇒ 23005<CR>R<CR> (not omitted)

A player needs a brief period after receiving a command before returning a Status Value or “R <CR>”. It is defined as follows:

T1 represents the time between the termination of the command string <CR> received and the beginning of the command execution. It is approximately 35ms maximum.

T2 represents the time for executing the command, depending upon the command type and the player’s condition. In case of a status request command such as “?F”, T2 requires less than 1ms.

T3 represents the time that is needed for transferring data (TxD) per byte. It requires a maximum of 6ms per byte. In case of the return data for “?F” request, a player is supposed to be back 8 bytes data, that is composed of 7 digit Frame number and “<CR>”. In this case the transfer time of each byte is not exactly the same with 6ms, it takes usually around 10ms for transferring 8 bytes data total, and it takes less than 20ms.

5.3.1 Reject

Function : Disc rotation stops Format : 99RJ Explanation : If the command is sent while the player is in Random Access

mode or Setup mode, the player enters Reject mode and the disc stops rotating. Once the disc completely stops, the player enters Park mode and returns the completed status message.

If the command is sent while the player is in Park mode, the player returns

the completed status message immediately without entering Open mode.

5.4 Start

Function : Disc rotation starts Format : SA Explanation : If the command is sent while the player is in Open, Park or Reject

mode, the player immediately enters Setup and the disc begins spinning up. The player is ready for playback when the device reaches the beginning of the program (DVD, CD or VCD disc pauses or stills at the first Track). The player returns the completed status when the disc pauses or stills.

If the player receives the command while playing a menu, the player returns

an error message. However, if the disc program does not allow new commands once playback begins, the player ignores the command.

5.5 Play

Function : Pictures and sound are reproduced (Option - Auto Stop) Format : (Address)PL Explanation : If the command is sent while the player is in Open mode, a DVD

disc plays according to the menu selection or from the first Title if a menu is absent. If the command is sent while the player is in Park, or Reject mode, a DVD disc plays from the first Title. A CD/VCD disc plays from the first Track. The player returns the completed status message after playback begins.

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 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.

If the Frame count difference is less than 24 Frames between the present

Frame and the specified Frame, the player returns an E06 error message and the marker is not set.

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 VOBU Still 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 returns an error message.

5.10 Multi-Speed Forward or Reverse (DVD)

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.

NOTE: These speeds are approximate values only.

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.

RS-232 Command Protocol

NOTE: DVD offers only fixed speed reverse. VCD offers 1/2 to 1/16 speed forward only. Sometimes, depending on its

forward speed, VCD Multi-Speed Forward may finish several frames earlier than the target address because playback does not rely on Frame counts.

Sometimes an Auto Stop command within a Multi-Speed command misses

the specific address. Depending upon when the command is sent, a playback address may be missed by a maximum of ten-Blocks.

The available address modes in each disc type are listed below:

5.11 Speed (DVD, VCD)

Function : Specifies the speed for Multi-Speed playback Format : Integer SP Explanation : The command rewrites the contents of the Speed Register and

returns the completed status message. The current mode of the player remains the same.

The speed parameter indicates the number of fields per second. The range is

0 through 90 with a default value of 15. The relationship between the integer, speed parameter and the actual speed of the player is as follows:

5.12 Search

Function : Search to specified address Format : Address SE Explanation : The specified address is written into the Search Register in

accordance with the current Search address mode.

When the Search command is sent to the player, the specified address is

compared with the current address. The pick-up is moved so that the difference becomes 0.

Upon reaching the specified address, the player enters the Pause mode for a

CD or the Still mode for others disc types. The player then returns the completed status message. If the player misses the specified address or cannot find it, an error message (E06 or E12) is returned. However, if the disc program disallows a Time, Chapter or Title Search, the player ignores the command and an error message (E04) is returned. In addition, if the disc program blocks the Pause command, the player ignores the command.

The DVD-V5000 does not accept other commands during the execution of a

Search command, returning an E04 error message. After issuing a Search command, wait until the Return (R) status appears before issuing another command. An exception to this rule is the Mark Frame Play command (i.e.

Function : Searches to specified address and starts to play immediately Format : (Address) SL Explanation : The specified address is written into an appropriate register

according to the Address. The player then compares the address with the current address. The pick-up moves so that the difference becomes 0.

The player plays a disc immediately after reaching the specific address. In

case the player misses or fails to locate the address, it returns an error code (E06 or E12). If Frame is selected in Address Mode, the player ignores the command.
