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:

- 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

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.

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.

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.

The player returns the completed status message immediately.

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.

If the player has read the Table of Contents (TOC) from a disc, the Lead-Out

Address or Frame Number can be translated into the lead-out Time.

The Lead-Out Search command on a CD or VCD disc stops the player at the

end of a program area prior to the read-out area while the Lead-Out Search
command on a DVD disc stops the player at the end of this Title.

NOTE: On a VCD disc, the Search address is set several seconds prior to the
lead-out point because the Lead-Out command requires the player to read

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.
