Probes that are unable to execute the user program (usually caused by interrupting the save-to-flash
process described above) can still be upgraded. Contact Sencore for details.
To verify that the probe is unable to start the user program, connect the USB cable as explained in
section 4.11.2 and reboot the probe. The diagnostics output will tell if the probe is unable to locate or
execute the user program.
If the web interface does not appear to work correctly straight after upgrading the probe it may be because
the web browser is using files that are cached. Files may be cached for up to one hour in the web browser.
To fix the issue, clear the cache manually:
Google Chrome: Settings – History — Clear browsing data. . . — Cached images and files
Mozilla Firefox: Options — Advanced — Network — Cached Web Content — Clear Now
Microsoft Edge: Settings – Clear browsing data — Choose what to clear — Cached data and files
Microsoft Internet Explorer:
Tools — Internet Options — General — Browsing history — Delete. . . —
Temporary Internet files
Note that the probe configuration may be lost when downgrading to an older software version. In this
case the saved configuration file may be useful.
