3. SERIAL CONTROL

3.1 Serial Interface Specifications

3.1.1 Signal Interface

The signal interface is an 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 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 default is 4800 baud.The player memorizes the transfer speed every time and that is retained after the power cycle reaches completion.

3.2 Communication 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.

- 4 -

3.3 Command 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” ⇒⇒ (2) Search Execution

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

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

Computer Control

⇐⇐ (3) Complete

⇐⇐ (6) Complete

• 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.

- 5 -

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:

- 10 -

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.

4.1 Command 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.

4.2 Argument

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.

Command Structure

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

Example : N

1N2N3

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.

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.

Command Structure

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.

4.4 Status Returns

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

Example: R<CR>

4.5 Error 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.

4.6 Request 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 -

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 request 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)

4.7 Timing

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.
