Lantronix XSENSO 21R2 Manual De Usuario

The xSenso  Logging tab/page provides access to the data logging feature available with browsers 
that support HTML5 and filesystem API (e.g., Chrome).  Users can run customized data logs 
through this page.  Upon the first visit, the browser will ask for your permission to allow this device 
to store data on your PC. Choose Ok. Browser will poll data from xSenso every period (1 minute 
default) as configured by user. Data is stored in the browser sandbox filesystem and its usage and 
total size is shown below the start/stop data logging button.  In the past, webpages were not 
allowed to access the PC's local filesystem because this would raise security issues (this is exactly 
what a virus wants to do). A browser supporting filesystem API allows webpage to save data in its 
own dedicated sandbox filesystem, which becomes the only accessible webpage. Data logging 
application stores data here and you can click on the filename to download these log files from the 
sandbox filesystem to anywhere on your local computer, just like downloading any file from the 
web. Please note that the browser stores data in sandbox filesystem per website, so it is 
recommended to have static IP, reserved IP address in DHCP server or access unit by hostname. 
It is recommended to use dedicated PC to log data to optimize data logging stability.
