7 FILESYSTEM
7.1 Overview
The interface card’s on-board filesystem is used by the application firmware. Currently, the application
firmware’s main use of the filesystem is to store XML-encoded configuration files and the embedded
web server. The studio must be used to manage the configuration via USB or FTP. Do not manually
access the configuration files unless instructed by technical support.
The configuration is only read at unit boot-up. Therefore, if a new configuration file is loaded, that unit
must be rebooted for the new configuration take effect. Rebooting a unit can be performed by power-
cycling the inverter in which the card is installed.
The embedded web server is customizable and is located in the “WEB” folder. All web page related
items should reside in the “WEB” folder.
Interacting with the filesystem can be performed via USB (using a mini-B USB cable) as the interface
card enumerates as a standard USB mass storage device “flash drive”. The file system can also be
accessed via FTP if the card has compatible network settings. Users can interact with the files on the
interface card’s filesystem in the same manner as though they were traditional files stored on a local or
remote PC.
Note that the USB and FTP connection will prevent the file system from being accessed by other
interfaces, such as the web server. Therefore, USB and FTP should only be connected when performing
