8.8 CLOUD MODE
8.8.1 DESCRIPTIONS
In the network configuration such as 4.2.3 STYLE 3: WAN-LAN, only one DL8 device can be accessed from WAN.
For a monitoring system with more than one DL8 device, the same number of routers are required, and may result in ex-
pensive communication cost.
In order to manage such a system at low cost, “Cloud Mode” is available in addition to web server function.
Using the cloud mode, the DL8 uploads files such as HTML files required for web browsing to a web server.
Data can be browsed by specifying the URL of the web server, not the one of the DL8.
Data uploading is achieved by FTP.
The web server must have FTP server function while the DL8 acts as a FTP client.
When uploading, a subfolder for each DL8 device can be specified.
The cloud mode is also useful when many operators browse at once the web screen of single DL8 device.
