Introduction
Thank you for purchasing the DN-700R. At Denon Professional, performance and reliability mean as
much to us as they do to you. That’s why we design our equipment with only one thing in mind—to
make your performance the best it can be.

General Overview
With serial remote control, a “host” machine (such as a PC running proper software) can be used to
operate your DN-700R. Throughout this document, the equipment used to control DN-700R will be
called the Host.
To learn more about the different types of serial communication and the code structure it requires, see
the Communication Protocol section that starts on the next page. To view the complete list of serial
command codes, see the Control Command Codes, Status Request Command Codes/Status
Information Codes, and Automatic Status Information Codes sections later in this manual.
Connecting the Host to DN-700R
For serial remote control, you must first connect the host to your DN-700R by taking one of the
following three steps:
Example 1
Use an RS-232C straight cable (9-Pin D-Sub Male) to connect the RS-232C input on the rear panel of
your DN-700R to the corresponding output on the host.

Example 2
Use an ethernet cable to connect the LAN port on the rear panel of your DN-700R to the corresponding
port on the host.
Example 3
Use an ethernet cable to connect the LAN port on the rear panel of your DN-700R to a router that the
host is also connected to.
Note: Only one network user can be connected to DN-700R at a time. This means that two different
computers cannot be used for serial communication with DN-700R at the same time, and you cannot
use the LAN port for serial communication while DN-700R is already being controlled by the web
browser remote.
After setting up for serial communication via an ethernet connection, entering the preset Admin
password will be required if the IP Control Auth setting is set to On in your DN-700R’s system
settings. To enter the password, you will need to send the “Admin Password” status request command
(included on page 24 in the Status Request Command Codes/Status Information Codes table). This
code is @0?LIxxxx\r, where xxxx stands for the password.
If the correct password is entered in the “Admin Password” status request command, DN-700R will
answer the host with the login successful code: @0LIOK\r. If the incorrect password is entered in the
“Admin Password” status request command, DN-700R will answer the host with the login failed code:
@0LING\r. After you receive the login failed code, you can try again to enter the password.

Communication Protocol
Types of Serial Communication
Three types of serial communication can be transmitted between the host and DN-700R:
1. Control commands sent to DN-700R from the
host
You can use control commands to make DN-700R
perform a desired function (such as initiating a
recording or playing a track).
When DN-700R successfully receives a control
command from the host, DN-700R sends an ACK
signal to the host and then executes the
command.
2. Status request commands sent to DN-700R
from the host
You can use a status request command to
determine the current state of one of DN-700R’s
components (such as the amount of free space left
on the media source or the currently selected
recording input).
When DN-700R successfully receives a status
request command from the host, DN-700R
answers the host with an ACK signal followed by
the requested status information.
3. Status information automatically sent to the
host when a change is made from DN-700R
When certain changes to DN-700R are made from
the device itself, DN-700R automatically sends
status information to the host. When the host
receives automatic status information successfully,
it sends an ACK signal to DN-700R.

Structure of the Codes
Serial communication between the host and DN-700R uses ASCII Code from 0x20 to 0x7F.
All control command codes, status request command codes, and status information codes require
three components that form a “packet.” In order, the components are the start character + ID, the
command, and the end character (0x0D):
1. Start Character + ID: @ (0x40) + 0 (0x30)
2. Command: some letters and/or numbers that stand for a controllable feature of DN-700R
3. End Character: \r (0x0D)
The required start character/ID and end character are the same in all codes, whereas the command
portion varies with each code.
For example, the full control command code that the host can use to power on DN-700R is @023PW\r:
@0 23PW \r
Rules on Transmitting Command Codes
•When DN-700R receives a control command or status request command from the host, DN-700R
should respond within 300 ms.
•When DN-700R successfully executes a command that it receives from the host, DN-700R sends
an ACK signal (0x06) to the host (as well as the status information code in the case of a status
request command).
•If DN-700R receives an unknown command from the host or if a received command fails for some
other reason, DN-700R will send a NACK signal (0x15) to the host.
•When sending consecutive commands from the host, do not send the second command until DN-
700R has answered the first with the ACK (0x06) or NACK (0x15) signal. If the second command is
sent before the ACK (0x06) or NACK (0x15) signal is received, DN-700R will send the “Busy” status
information code (@0BDERBUSY) to the host.
•If DN-700R does not receive a command that the host sent within 300 ms, the host will
automatically send the same command up to two additional times. If DN-700R still does not receive
the command after the second automatic attempt, the process will timeout, and the host will send
the end character to DN-700R.
•Do not send a second status request command from the host until DN-700R has responded to the
first.
•When sending a command to DN-700R from the host, make sure that no longer than 5 ms passes
between entering each character in the command code.
•All characters used in codes transmitted between the host and DN-700R must fall within the
bounds of the acceptable character table in the Appendix.
•Wait at least one second after sending the Power On command before sending the next command.
•When status information is automatically sent to the host after a change to DN-700R is made from
the device itself, the host will send an ACK (0x06) signal to DN-700R. If DN-700R does not receive
the ACK signal within 300 ms, it will automatically send the status information to the host again. If
DN-700R then fails to receive the ACK (0x06) signal again, the process will timeout.
