If you have software before v3.4 you can get a replacement update board to update your NateChrony to the latest software version.
This is a one-off purchase of a new circuit board and physically replace it to get an update. The software version is in the lower right corner of the shot screen, if there is no version number - it is v1.
If you have a version of software from v3.4 onwards, then it can be updated remotely. To update remotely - we will organise a quick call and guide you through the procedure.
