Frequently Asked Questions
  • What the SD card in DB91-TX can be used for and how?
    The SD card stores the System Log files. They are available in section Other of the WEB Interface, subsection System Log. Pressing the [View] button will visualize them on the screen.
  • How should I configure the connection between DB91-TX and the FTP Client?
    The FTP facility allows you to access the SD card and download the gathered System Log Files. A standard FTP client should be used in order the device to be accessed via FTP. We recommend the usage of FileZilla. This is a widespread open source software distributed free of charge, hence available for downloading from the Internet. Detailed explanation on how should the connection be configured can be found in the complete User manual.
