IMPORTANT  
THIS PIONEER APPARATUS CONTAINS  
LASER OF CLASS 1.  
SERVICING OPERATION OF THE APPARATUS  
SHOULD BE DONE BY  
INSTRUCTED PERSON.  
A
SPECIALLY  
LASER DIODE CHARACTERISTICS  
FOR DVD : MAXIMUM OUTPUT POWER : 5 mW  
WAVELENGTH : 655 nm  
FOR CD : MAXIMUM OUTPUT POWER : 5mW  
WAVELENGTH : 785 nm  
LABEL CHECK  
DVD-V7300D/WYV/RB only  
DVD-V7400/KU/CA only  
DRW1995-A  
Additional Laser Caution  
1. Inside detection switch (S201 on the SMEB assy) and loading-  
status detection switch (S301 on the LOSB assy) are detected  
by the microprocessor (IC11 in the DVDM assy).  
• To permit the laser diode to oscillate, it is required to set the  
inside detection switch for the inside position (S201 : ON) and to  
set the loading-status detection switch for the clamp position (the  
center terminal of S301 is shorted to +5V). The 655 nm laser  
diode for DVD oscillation will continue if pin 19 of IC1 is shorted  
to +5V (fault condition) in the DVDM assy.  
The 785 nm laser diode for CD oscillates if pin 20 of IC1 is shorted  
to +5V in the DVDM assy.  
In the test mode ∗ , the laser diode oscillates when microproces-  
sor detects a PLAY signal, or when the PLAY key is pressed  
(S159 ON in the KEYB assy), with the above requirements satis-  
fied.  
2. When the cover is open, close viewing through the objective lens  
with the naked eye will cause exposure to the laser beam.

5. PCB PARTS LIST  
NOTES: Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.  
•
The mark found on some component parts indicates the importance of the safety factor of the part.  
Therefore, when replacing, be sure to use parts of identical designation.  
•
When ordering resistors, first convert resistance values into code form as shown in the following examples.  
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,  
•
and K=10%).

7.1.2 Display of the Error History  
• The type, date and time, and the number of occurrences of errors  
of the player can be recorded.  
How to display the error history  
• Press the ESC, TV/LDP, then SIDE A keys on the remote control  
Up to 8 types of errors can be recorded, and the number of  
occurrences can be counted up to 255 per error type.  
The date and time of the latest error is recorded per type. The date  
and time are based on the real-time clock built into the player.  
unit for service use, in that order.  
How to clear the data of the error history  
• While the error history is displayed, press the CLEAR key on the  
remote control unit for service use.  
If the real-time clock has not been set or the setting is wrong, the  
dates and times of occurrence recorded will be those of the clock  
at that time.  
Display of power-on and playback duration  
• The power-on duration and playback duration of the player can be  
recorded.  
• An example of the error history display is shown below:  
Example of the error history display  
See below for how to display power-on and playback  
duration.  
• Power-on duration: Accumulated power-on duration of the player.  
Date and time of occurrence of  
the latest error: 16:02, Nov. 5  
• Playback duration: Accumulated playback duration of the player.  
Duration is counted even in Pause and Still modes. This playback  
duration can be considered to be the spindle motor's duration of  
rotation or duration of use of the laser diode.  
Error count: Up to 255  
("FF"), in hexadecimal  
Error code  
Note: The power-on duration and playback duration are measured  
using the CPU clock of the player, so you should allow for  
about 2% error. Use these displays merely as a guide for  
servicing.

• The data of the power-on and playback duration are not cleared if  
the player's software upgrade is downloaded from the dedicated  
web site.  
(As for the DVD-V700, the data of the power-on and playback  
duration are cleared when the player's software is upgraded.)  
How to display power-on and playback duration  
• While pressing the DISPLAY key of the main unit, set the POWER  
switch to ON. (This is also explained in the Operating Manual.)  
• In the above example, two types of errors are recorded, and six  
other types of errors can be further recorded. In the above two  
cases (error codes "11" and "C3"), the error history will be recorded  
until their error count becomes "FF."  
• The data of the error history can be cleared if the number of error  
types reaches eight or the number of errors reaches 255. After the  
data of the error history are cleared, new errors can be recorded.  
(Cleared data of the error history cannot be restored. It is  
recommended that the data of the error history be written down  
before clearing.)

7.1.5 SERIAL CONTROL  
When using a computer to control the DVD-V7400/V7300D player,  
follow the command protocols listed below:  
ASCII characters are used for actual commands and status  
response  
1. Serial Interface Specifications  
Signal Interface  
The signal interface is a standard RS-232C connection.  
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  
Data Type  
Data Length: 8 bit  
Stop Bit:  
Parity bit:  
1 bit  
No Parity  
(e.g. chapter number or speed)  
Use a command as the terminator of an argument  
Data Transfer Speed (Baud Rate)  
The data transfer speed may be set to either 4800 or 9600 baud  
through the Industrial player menu screen and/or with the Advanced  
Feature Menu Set command (please refer to the DVD-V7400/  
V7300D Operating Instructions and the Advanced Feature Menu  
Set command description).  
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>  
10SE<CR> : Search to chapter 10  
: Set chapter for address mode  
NOTE: The factory default is 4800 baud; however, the player  
memorizes the transfer speed each time the power is  
cycled.  
The player has a command buffer, which stores a command string  
of up to 32 characters in length.  
2. Communication with a Computer  
Example:  
The DVD-V7400/V7300D 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.  
10SE 20PL<CR> : Search to chapter 10 then play to 20  
The command string enters 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.  
Computer  
TxD  
DVD-V7400/7300D  
RxD (Pin 3)  
TxD (Pin 2)  
GND (Pin 1)  
NOTE: The player ignores codes in the command string such as  
<SPACE> or <LF> (line feed) which do not affect the  
player's operation.  
RxD  
GND  
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.  
Some computers require the CTS port to be set to HIGH during  
communication. It is best to connect the CTS 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.  
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.  
3. Command and Status  
During normal operation, a computer transmits commands to a  
DVD-V7400/V7300D and the player responds with the status  
message, 'execution complete'.  
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.  
Example:  
COMPUTER  
(1) "Search to Frame 1000"  
DVD-V7400/V7300D  
(2) Search Execution  
(3) Complete  
\
|
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).  
(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.

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 the video text is displayed.  
A command issued without one of these sequences causes the player to return an error code E04.  
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.  
If a command requires an argument, it is always placed before the command.  
Example :  
Minimum 000 ~ Maximum 300  
N1N2N3  
(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 String  
Timing  
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).  
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 String  
<CR> is received to the beginning of the execution of the  
command extension. The maximum is approximately 24ms.  
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.  
T2 represents the time it takes to execute the command.  
Depending upon the command type and the player's condition,  
the minimum is 14ms.  
RxD  
P
L
<CR>  
Once the <CR> termination command is added to the string, the  
command string is evaluated and executed from left to right in  
sequential order.  
T1  
T2  
Execute  
TxD  
If an error occurs during the execution of a String, the remainder of  
the string following that command is not executed.  
R
<CR>  
=
+
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.  
T3  
Playback in External Sync Mode  
To cancel a currently executing string, send the termination command  
<CR> alone.  
In External Sync mode, the player synchronizes the transition from  
the reception of a PL (PLAY) command to playback or from Still  
mode to playback with a Vertical Sync signal for simultaneous start  
of multiple players. Therefore, the timing for starting playback can  
be controlled by the timing of sending the PL command to the  
players, as described below.  
If a new command without Text File Data Upload [UU] is input  
while playing the current command stack, the remaining commands  
are cleared.  
Status Returns  
The completion message used in the Automatic Status is "R".  
Playback starts from the first field, which is located three fields  
after the PL command was received in video Still mode. The  
indeterminate area is a 7-msec period from the beginning of a  
second field. If a CR at the end of the PL command falls into this  
indeterminate area, the timing of the start of playback will be either  
as shown below or one frame before.  
Example: R<CR>  
Error Message  
An error message is indicated by the letter E and followed by a two-  
character error code.  
2nd Field  
1st Field  
Example: EN1N2<CR>  
The error message occurs when the given command cannot be  
processed.

Request Status Return  
In response to a single request command, the status returns as a line  
of letters terminated by <CR>.  
The PL command in External Sync mode is the only command to  
be executed in synchronization with the Vertical Sync signal.  
If multiple request commands are sent to the player 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 request command is at the end of the command string, the  
R within the completion message is omitted.  
Example:  
ST?F<CR>  
Example:  
?FST<CR>  
\
\
23005<CR> (completion omitted)

7.1.6 PARALLEL CONTROL  
1. External Switch Control  
To control the player through the Serial Interface Connector, use a  
switching circuit with pins terminated to a +5 volts DC / internal  
20,000 ohms resistor.  
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.
