1 Serial Remote Control Terminal
Remote control of the DN-V300 is possible by connecting the serial interface of a PC, etc., to the serial
remote terminal on the rear panel. The commands usable with serial remote are categorized in three
groups, the PC group controlling the DN-V300, the PS group for acquiring information on the
DN-V300’s operating status, and the PR group of status information issued asynchronously from the
DN-V300 in response to changes in operating status. The details of the commands are described each
group. The DN-V300’s serial remote terminal is compatible with RS-232C standards.

NOTES
 Use a male/female serial straight cable to connect to a personal computer.
 To prevent damage to the DN-V300 and the controller, turn off the power of both the
DN-V300 and the controller when connecting the serial cable.
 Also be sure the settings of the control side’s communications specifications (data length,
baud rate, stop bit, flow and parity) match those of the DN-V300 (shown on the table above
at the left).
 The DN-V300 cannot be used with CTS and RTS signals. If such signals are being received
and controlled on the controller, take the proper measures for the controller’s software
and/or hardware.

2 Serial Remote Control
 Basic Protocol for Sending and Receiving Commands
The basic protocol of this interface is a method in which the device with which serial communications
are possible (hereafter called “the controller”) issues commands and the DN-V300 returns the message
that execution has been completed.
When using a personal computer, serial communications are possible using Hyper Terminal included
as a standard with Windows95™ and later.
 Command format
ASCII character codes are used for commands and messages. Command sections are expressed with
two characters. Only the command texts specified for a combination of capital and small letters the
each command can be received.
The basic format of transmission commands is [group,command,parameterlist], terminated by the
<CR> code (0DH). The DN-V300 recognizes the end of a command through this code.
The parameter ranges are defined for each command (some commands have no parameters), so send
in a format conforming to that command’s specifications.
Example: Controller [PC,PlayT,1]<CR> ：Issues a command for playing Title No. 1.
DN-V300 [PC,PlayT,0] ：
The DN-V300 plays the assigned title and returns the error code 0 (no error).
 Command transmission and reply message
When the DN-V300 receives a command and completes the instructed task or when an error occurs,
the DN-V300 returns a reply message to the controller. The reply message consists of the sent
command to which an error code is added. There are five types of error codes:
 Error code indicating acknowledge reception: 0
 Error code indicating that an error of undetermined cause has arisen: 1
 Error code indicating that the sent parameter is invalid for the DN-V300’s operating status: 2
 Error code indicating that the command is invalid due to a parameter range or format violation: 5
 Error code indicating that the command is invalid for the loaded disc type: 10
The different commands corresponding to the various device statuses are shown on the table on page 8.
1. PC group ：External control of the DN-V300 using various commands from the controller.
2. PS group ：Request of sending of operating status from the controller to the DN-V300.
3. PR group ：Issue of description of change of status when DN-V300 is not synchronized
due to a change of status.

Serial Remote Control (continued)
Send one command at a time.
Example: When playing a DVD, pause after playing Title 1.
[PC,PlayT,1]<CR> →Command to play Title 1 sent from controller.
[PC,PlayT,0] ←Reply of error code 0
( no error ) from DN-V300.
[PC,RC,48]<CR> →Pause command sent from controller.
[PC,RC,0] ←Reply of error code 0
( no error ) from DN-V300.
[PR,StatusChange,0,5] ←
Issue of status change (pause) message from DN-V300.
 Error codes
If the structure of the command from the controller was wrong or the contents of the command were
invalid for any reason, a message consisting of an error code added to the sent command is returned.
List of error codes
Error code Name Description
0 No error Message received normally.
1 Cause of error not known Error of unknown cause has arisen.
2 Invalid parameter Invalid parameter received.
5 Command not valid Invalid message structure detected.
Parameter outside of specified range received.
10 Command not valid for
Current disc
Message invalid for current disc type received.
Example: When a command for starting to play Title 80 on a disc only including 20 titles was sent.
[PC,PlayT,80]<CR> →Command to play Title 80 sent from controller.
[PC,PlayT,2] ←Error code 2 returned from DN-V300 and no response.
 Command reference
Commands are combinations of two ASCII code characters.
The basic format of transmission commands is [group,command,parameterlist]<CR>.

3 Description of PC Commands
 Detailed Description of Commands
Ⅰ. External Control Commands: PC group
Detailed description of the external control commands in the PC group
1. Remote control command (RC) ---- Valid in the same way as IR remote control
<Format> [PC,RC,RC code]<CR>
(For the RC code, refer to the PC RC command control parameters on page 7.)
<Reply> [PC,RC,Error code] (For the error codes, refer to the list of error codes on page 6.)
<Details> ・All IR remote control key operations can be controlled by serial remote.
・Send RC codes following the “List of PC RC command control parameters”.
Example: To start playback
[PC,RC,44]<CR> →Code 44 (Play) is sent from the controller.
[PC,RC,0] ←
Error code 0 (no error) is returned from the DN-V300 and playback starts.
※ When in the power off standby mode, basically PS and PC group commands are not accepted.
The following three PC RC commands are accepted, however.
[PC,RC,12]<CR> ( DVD POWER )
[PC,RC,44]<CR> ( PLAY )
[PC,RC,66]<CR> ( OPEN/CLOSE )
2. Play title or track command ( PlayT ) ----- Valid for DVDs, CDs, and VCD/SVCD （ only when PBC off ） discs
<Format> [PC,PlayT,Title or Track No.]<CR>
<Reply> [PC,PlayT,Error code] (For the error codes, refer to the list of error codes on page 6.)
<Details> ・
For DVDs and VCDs: In the stop, play and pause modes, playback of the assigned title starts.
・For CDs: In the stop, play and pause modes, playback of the assigned track starts. In
the pause mode, however, the player remains in the pause mode.
・If a title or track number that does not exist on the disc is specified, error code 2 is
returned and control is not accepted.
・For CD-R/RW discs containing MP3 files, JPEG files, etc., error code 10 is returned
and control is not accepted.
Example: To start playing title 1
[PC,PlayT,1]<CR> →The command to play title 1 is sent from the controller.
[PC,PlayT,0] ←
Error code 0 (no error) is returned from the DN-V300 and playback starts.
3. Play chapter command ( PlayC ) ---- Valid for DVDs and VCD/SVCD (only when PBC off) discs
<Format> [PC,PlayC,Title No.,Chapter No.]<CR>
<Reply> [PC,PlayC,Error code] (For the error codes, refer to the list of error codes on page 6.)
<Details> ・ In the stop, play and pause modes, the specified chapter of the assigned title’s chapter starts playing .
・If a title or chapter that does not exist on the disc is specified, error code 2 is returned.
・If a disc other than a DVD or VCD (only when PBC off) is loaded, error code 10 is
returned and control is not accepted.
・For VCDs, title numbers are handled as track numbers, chapter numbers as entry
numbers, and the entry number is fixed to “1”.

１０
Example: To start playing title 1 chapter 5
[PC,PlayC,1,5]<CR> →
The command to play title 1 chapter 5 is sent from the controller.
[PC,PlayC,0] ← Error code 0 (no error) is returned from the DN-V300 and playback starts.
