1 Serial Remote Control Terminal
Remote control of the DN-V310 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-V310, the PS group for acquiring information on the
DN-V310’s operating status, and the PR group of status information issued asynchronously from the
DN-V310 in response to changes in operating status. The details of the commands are described each
group. The DN-V310’s serial remote terminal is compatible with RS- 3 C standards.

NOTES
 Use a male/female serial straight cable to connect to a personal computer.
 To prevent damage to the DN-V310 and the controller, turn off the power of both the
DN-V310 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-V310 (shown on the table above
at the left).
 The DN-V310 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-V310 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-V310 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-V310 [PC,PlayT,0] ：
The DN-V310 plays the assigned title and returns the error code 0 (no error).
 Command transmission and reply message
When the DN-V310 receives a command and completes the instructed task or when an error occurs,
the DN-V310 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-V310’s operating status:
 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-V310 using various commands from the controller.
. PS group ： Request of sending of operating status from the controller to the DN-V310.
3. PR group ： Issue of description of change of status when DN-V310 is not synchronized
due to a change of status.

 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.
