The firmware on our latest generation of instruments (RBRvirtuoso/duo/concerto/maestro, RBRsolo/duet) is field upgradable through our Ruskin software. If you are running Ruskin on a computer connected to the internet, and plug in a logger, Ruskin will automatically check if a new firmware version is available, and will ask you if you would like to upgrade your logger. You can also manually upgrade the firmware in Ruskin, under the Instruments menu, select Upgrade logger firmware.
Firmware updates for legacy instruments such as the XR series or TDR instruments may not be possible depending on the age of the instrument. If the firmware can be updated, it will require the instrument to be returned to the factory, and the upgrade would be a chargeable service item.
