Denon DN-700R setup

Theory of Operation

The DN-700R MP3 recorder is configured to copy its audio files (via FTP) onto the Dharmaseed website after each recording is completed. A modified router is used to provide a secure link between the recorder and the website’s FTP server. The security measures are taken to allow the recorder alone to access the Dharmaseed website’s FTP server – without the router, the website’s FTP service is inaccessible.

Wiring

Router Setup

Connect the recorder to one of the router’s LAN ports, supply power and switch it on. The recorder’s built-in administration and configuration pages can be accessed from a web browser on a test PC that is connected to the Dharmaseed router (see diagram above). You access it via the recorder's IP address.

Recorder IP Address

To find the recorder’s IP address (once it has been connected to the router and started), push the MENU button and use the REC LEVEL knob to scroll to 09 Utility. Next, momentarily push the REC LEVEL knob and then use it to scroll to 05 Network Status. Push the knob in again and you will see the IP address displayed. It should be something similar to 192.168.050.1xx. Use that address in the URL to access the configuration pages.
