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
Computer Control
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:
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).

Computer Control
3.1 Serial Interface Specifications
The signal interface is a standard RS-232C connection.
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).
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 Pin 3 - RxD
RxD
GND
Pin 2 - TxD
Pin 1 - 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.

Computer Control
3.3 Command and Status
During normal operation, when a computer transmits commands to a DVD-
V7400, the player responds with the status message, ‘execution complete’.
Example
(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 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 <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 have no affect on the player.
- 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
Computer Control
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
E04 error Communication Line Error due to framing error or buffer overflow
Feature not available Non-Usable Function has been tried – either the command mnemonic is wrong or the command can not be used in this mode

Command Structure
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.
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 300
N
1
N
2
N
3
(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 ten characters and/or digits.

Command Structure
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.
The completion message used in the Automatic Status is R.
Example: R<CR>
- 11
Command Structure
An error message consists of an E followed by a two-character error code.
Example: EN
1
N
2
<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 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.
10260<CR>
When the command is at the end of the command string, the R within the completion message is omitted.
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
PL<CR>
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.
- 13
Command Structure
Only the PL command under external synchronization, is executed during the V sync timing.
Example:

Function : Pictures and sound are reproduced (Option - Auto Stop)
Explanation : If the command is sent while the player is in Open, Park, or
Reject mode, a DVD disc plays according to the menu selection or from the first Title if a menu is absent. A CD/VCD disc plays from the first Track. The player returns the completed status message after playback begins.
- 16
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:

5.13 Multi-Speed Forward (DVD, VCD)
Function : Playback occurs at the speed specified in the Speed Register
(Option - Auto Stop)
(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.
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.

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.

Function : Search to specified address

speed reverse
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.

The Stop Marker is cleared when the player reaches the marked address via a Play command, a Multi-Speed operation or other action. The player enters the Pause mode (CD) or the Still mode (other disc types) with no messages returned. However, if the disc program does not allow a pause, the player ignores the command.
If the Frame count difference is less than 24 Frames between the present
Frame and the stop marker address, the player returns an E06 error message and the marker is not set.
A Time Code or Chapter Number request notes if the player reaches the marked address. The Clear and Reject commands remove the marker.
- 24
Command Descriptions
The Stop Marker is the same in functionality as the Play (or Multi-Speed)
Auto Stop commands. The primary difference is when the player return a status message. The Multi-Speed Auto Stop command returns the completed status message when the player reaches the marked address.

Operating Modes
The Operating or Active mode consists of five sub-modes; Open, Park, Setup, Random
Access and Reject. A command causes the player to change from one sub-mode to another. The five sub-modes are described below.
7.1 Open
The disc tray is open.
7.2 Park
The player enters the Park mode when the tray is closed.
7.3 Setup
If the Start command is sent while a disc is in the player, the disc spins up and the player proceeds to the Setup mode.
The player enters the Random Access mode when the disc is ready for playback.
The Random Access mode is divided into six sub-modes; Play, Still, Scan,
Pause, Multi Speed and Search. Various picture controls in the Random Access mode are available when playing a DVD or VCD disc. The effects are achieved through highly-detailed mode transfers. Refer to the previous figure for mode relationship information.
- 81
Operating Modes
7.5 Reject
When the Reject command is sent to the player, video playback stops. Once the disc rotation has stopped, the player enters the Park mode.
- 82
Internal Registers
8. DVD-V7400 INTERNAL REGISTERS
When arguments (e.g., Title number, Chapter number, Time Code, etc.), accompany commands to the player, argument values are set in the appropriate player registers.
This Chapter describes each internal register of the player.
The register contains the current time while a DVD disc is playing; however, the register retains the Frame number when a LB-compatible DVD disc (CAV) is playing. A CD/VCD disc provides both a current Time Code and a Block number within the register.
8.2 P-TIME
The P-TIME Register contains the elapsed time within a Track or a Chapter.
8.3 Current Title/Track (Current Chapter)
The register contains the current Title/Track Number (Chapter Number).
The register contains the current Index number.
8.5 Serial Digit Buffer
The register contains the command argument values. The commands are placed in a separate, exclusive register.
When the player evaluates a command, the contents of the buffer are transferred to a specified register.
8.6 Remote Control Use Address Flag
When a Search command is sent through the remote control to the player, a flag specifies if the address assigned is a Title/Track, Chapter, Time or Frame.
8.7 Remote Control Digit Buffer
The register contains the numbers input through the remote control.
- 83
Internal Registers
8.8 Remote Control Data Register
The register contains the temporary data input through the remote control.
8.9 Laser Barcode Buffer
The register contains the compatible Laser Barcode data transmitted via the remote control.
8.10 Serial Use Address Flag
When the Serial Interface controls the player, a flag specifies if the address assigned is a Title/Track, Chapter, Time, Frame, Index, Block or ID.
The register contains a goal Title/Track number (Chapter number) which displays as a Frame number, Time Code or Block number.
8.12 Search Title/Track (Search Chapter)
The register contains a goal Title/Track number (Chapter number) during a
Search.
This function is identical to the Search Time/Frame command (refer to 8.11).
The register contains a goal Index number during a Search.
This function is identical to the Search Time/Frame command (refer to 8.11).
The register contains a marker (representing the Frame number, Time Code or
Block number) which indicates the end point of an Auto Play.
When the player performs an Auto Play, the contents of the Mark Time/Frame and the Current Time/Frame are compared.
- 84
Internal Registers
8.15 Mark Title/Track (Mark Chapter)
The register contains the Title/Track (mark Chapter) as a marker.
The function is identical to the Mark Time/Frame command (refer to 8.14).
The register contains the Index number as a marker.
The function is identical to the Mark Time/Frame command (refer to 8.14).
The player uses the register to control the Video ON/OFF switch.
The player uses the register to select the audio output.
The player uses the register to toggle the Character Display switch ON/OFF.
The Character Display tracks on-screen information such as Time/Frame number, Title/Track number, etc.
8.20 Registers
There are three (3) registers, A B and D. The registers are reserved exclusively for CPU internal operations.

9. EXTERNAL SWITCH CONTROL
To activate a function, create a switch contact with an electrical ground (Pin 1). Check
Chapter 2 to verify pin (Pin 6 through Pin 13) and terminal (SW1 ~ SW8) assignments.
There are three SW functions in the EXTERNAL SWITCH CONTROL.
1. To recall Barcode/Command Stacks and execute
The function, STACK GROUP 1 to STACK GROUP 27, is similar to a combination of remote control buttons to recall and execute a stack.
2. To execute the function as a remote control command
The function acts the same as the buttons (ENTER, PLAY, STOP, etc.) on a remote control excluding SCAN FWD/REV.
A scan request sent through the remote control may be Paused. However, once a scan command is halted, the request is lost.
3. To execute as an advanced remote control button
Advanced remote control commands such as OPEN/CLOSE, numbers from 10 to
20, and the four slanting arrows may be sent as a switch control command.
Note for additional assistance, please refer to Product Information Bulletin (PIB) 152601
DVD-V7400 and Jama Port Control available on the Pioneer Electronics website under
Service & Support – Business Solutions Products.
