Series 4.0 - Firmware

The Avisaro products are shipped with firmware installed. In rare cases, it may be necessary to perform a firmware update. We strongly advise you to update only if necessary.

There are three update paths:

  • Via USB Stick: Unpack the zip file. Copy the file 'avi40up.bin' to a USB stick and insert the stick. After approx. 5 seconds, the LED flashes white and indicates the update process. After approx. 15 seconds, the logger automatically switches to the normal operating state and the LED lights up as usual. 

    Never interrupt a running update - this can lead to the defect of the logger.

  • Via PC Software: Connect the logger to the PC and use the "Avisaro PC Companion Software". Via the menu item "Firmware Update" the file 'avi40up.bin' can be transferred to the logger. Then click on 'Do Update'. The logger flashes white briefly and then returns to normal mode.
  • Via Remote Update: For loggers with cloud or FTP connection, an update can be made via the Internet. Ask us for details.
