More precisely: the electronics of a Quatro that was operated in parallel with a second one broke (firmware 2631490). The only replacement I get is the Quastro with firmware 2634190. What can I do to let the two devices run in parallel again?

The first four numbers (hardware ID) have to be the same.

The firmware version is the XXX part. This you can change.


2634 and 2631 are the hardware versions. This you can't change.
