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

2.3.2 External Switch Control (see Chapter 9)

Control the player with the External Option Switches (SW#). Please check the condition of the Key Lock. If the Key Lock is set

(active), the player ignores the control. Please refer to the Key Lock command description.

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:

Computer Control

Maximum Input Voltage Less Than

m 12V

High Level Signal More Than 4.5V Low Level Signal Less Than 0.5V

Standby mode

more than

100 msec

Power ON

Power ON mode

more than

100 msec

Power OFF

Check the Key Lock condition. If the Key Lock mode is active, the player ignores the control (refer to the Key Lock command description).

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 4800 or 9600 baud through the Industrial player menu screen or with the Advanced Feature Menu Set command (refer to the DVD-V7400 Operating Instructions for command description).

Computer Control

NOTE: The factory default is 4800 baud; however, the player memorizes the transfer speed each time the power is cycled.

3.2 Communication with a Computer

The DVD-V7400 communicates to the computer through the 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-V7400

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.

Pin 3 - RxD

Pin 2 - TxD

Pin 1 - GND

3.3 Command and Status

During normal operation, when a computer transmits commands to a DVDV7400, the player responds with the status message, ‘execution complete’.

Example

COMPUTER DVD-V7400 (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-V7400 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 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 have no affect on the player.

Computer Control

<CR> is entered, the commands are

- 5

Computer Control

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 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 non-recorded 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:

• ?P to determine the Active mode of the player

• ?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.

• ?F, ?T, ?C, or ?R to determine the current Frame, Time, Chapter,

Title/Track number, respectively.

• ?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:

- 6

3.4 Error 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

E04 Feature not available

E06 Missing argument E11 Disc does not exist E12 Search error

E15 Picture stop

NOTE: Commands prefaced with an *1 are supported by only DVD-V7400.

- 9

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

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.

NOTE: Do not issue a command without a Text File Data Upload [UU], Reject [RJ] or Open [OP] sequence while videotext is displayed. A command issued without one of these sequences causes the player to return an E4 error code.

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 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 ten characters and/or digits.

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.

• 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]

• 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 Text File Data Upload [UU], [?*], [#*] or [$*] is input while playing the current command stack, the remaining commands are cleared.

The DVD-V7400 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.

Command Structure

4.4 Status Returns

The completion message used in the Automatic Status is R.

Example: R<CR>

- 11

4.5 Error Message

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

Command Structure

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>.

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)

<CR>

4.7 Timing

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 4ms 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 4ms, it takes usually around 10ms for transferring 8 bytes data total, and it is supposed to take less than 16ms.

4.8 Start Timing Under Synchronized Playback (with several players)

To synchronize each playback to External Reference Sync Signal among several players, issue the PL command after all players have finished the Search. The next chart indicates the when to issue the PL command.

SE <CR>

R<CR>

> 300 msec

When the player executes a Search (SE command) and it returns a completion message, there is a brief period when the player ignores a PL command. Issue a PL command at least 300ms after the command completion.

After issuing a PL command, there may be a brief period before synchronized playback starts. If all players receive a PL command after a Search but before the PLAY command is issued (see following example), then playback is synchronized after a pause of approximately three fields which is less than one Frame in length.

When the player receives a PL command during the Unspecified Area (see below), the playback might start at the first field, just after the first field, or it might start after waiting for one Frame (four fields). Thus, this playback location is called an Unspecified Area.

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 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 returns an error message.

The available address modes are listed below:

playback)

Explanation : If the command is sent while the player is in Random Access

mode, the screen proceeds forward (NF) or in reverse (NR) quickly. When scanning is finished, the player resumes the Random Access mode and returns the completed status message.

If the SCAN command is sent while the player is in Fast Forward or Reverse

Playback, the player enters Scan mode.

Once the NS command is sent, the player resets to the normal Playback

mode and returns the completed status message.

5.13 Multi-Speed Forward (DVD, VCD)

5.14 Multi-Speed 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.

Command Descriptions

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.

NOTE: DVD offers 1, 1/2, 1/4, 1/8, 1/16, STEP1 speed reverse when REV STEP/REV PLAY is set to FRAME on a ADV. SETUP menu or offers only SLOW speed reverse in case it is set to VOBU.

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 then the target address because playback does not rely on Frame counts.

- 20

Command Descriptions

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:

5.16 Search

Function : Search to specified address

speed reverse

speed forward

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 can not find it, an error message (E06 or E12) is returned. However, if the disc program disallows a Time or Chapter 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-V7400 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.
