1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.

ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL
SHOCK HAZARD AND MUST BE CORRECTED BEFORE
RETURNING THE APPLIANCE TO THE CUSTOMER.

LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
such as Simpson Model 229-2 or equivalent between the
earth ground and all exposed metal parts of the appliance
(input/output terminals, screwheads, metal overlays, control
shaft, etc.). Plug the AC line cord of the appliance directly
into a 120V AC 60Hz outlet and turn the AC power switch
on. Any current measured must not exceed 0.5mA.

2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related characteristics. These are
often not evident from visual inspection nor the protection
afforded by them necessarily can be obtained by using
replacement components rated for voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this Service Manual.
Electrical components having such features are identified
by marking with a on the schematics and on the parts list
in this Service Manual.
The use of a substitute replacement component which does
not have the same safety characteristics as the PIONEER
recommended replacement one, shown in the parts list in
this Service Manual, may create shock, fire, or other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current PIONEER Service
Manual. A subscription to, or additional copies of, PIONEER
Service Manual may be obtained at a nominal charge from
PIONEER.

IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.

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 loadingstatus 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 microprocessor detects a PLAY signal, or when the PLAY key is pressed
(S159 ON in the KEYB assy), with the above requirements satisfied.
2. When the cover is open, close viewing through the objective lens
with the naked eye will cause exposure to the laser beam.
∗ : See page 50.

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.
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.
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.
• An example of the error history display is shown below:

How to display the error history
• Press the ESC, TV/LDP, then SIDE A keys on the remote control
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.

Display of power-on and playback duration
• The power-on duration and playback duration of the player can be
recorded.

See below for how to display power-on and playback
duration.
• Power-on duration: Accumulated power-on duration of the player.
• 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.
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
• 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.)

54

• While pressing the DISPLAY key of the main unit, set the POWER
switch to ON. (This is also explained in the Operating Manual.)

7.1.5 SERIAL CONTROL
1. Serial Interface Specifications
Signal Interface
The signal interface is a standard RS-232C connection.

Data Type
Data Length: 8 bit
Stop Bit:
1 bit
Parity bit:
No Parity

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

2. Communication with a Computer
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.
Computer

DVD-V7400/7300D

TxD

RxD (Pin 3)

RxD

TxD (Pin 2)

GND

GND (Pin 1)

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.

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'.
Example:
COMPUTER
(1) "Search to Frame 1000"
(4) "Play to Frame 2000"

DVD-V7400/V7300D
(2) Search Execution
(3) Complete

\

(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/V7300D 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
 is received. The  acts as the command line terminator.
Example:
CH
: Set chapter for address mode
10SE : 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 : 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  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
 or  (line feed) which do not affect the
player's operation.
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.
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 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).

59

DVD-V7400, DVD-V7300D

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:
Status Reporting
Auto Status
Auto Completion Message
Error Indication Message
Request Status

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:

NOTE: Commands prefaced with an *1 are supported by firmware
Version 2.00
NOTE: Commands prefaced with an *2 are supported by firmware
Version 2.20
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.

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
Minimum 000 ~ Maximum 520703

N1N2N3
(except MS command)
(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
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  code
(0DH hex).
Example : FR2000SE 2300PL
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.

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 String
 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.
RxD
P

Once the  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 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.
To cancel a currently executing string, send the termination command
 alone.
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".
Example: R

Error Message
An error message is indicated by the letter E and followed by a twocharacter error code.

Playback in External Sync Mode
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.
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.

1st Field

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 .
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 
termination code.

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.

2. Function Assignment
Each function of the external option switch is greatly classified into
three.
1. Key which calls and executes group of bar code/command stack
• Stack grop1-27 of the function is key which executes command
stack which registers (MEMORY key + ENTER) in the remote
control key.

2. The one to do the same function as key to remote control unit.
