Hi, in June 2021 we bought 2 2120's from Corselusa, with serial numbers 20012410 and 938357.
The former works but the latter wouldn't load Fast Bal II (we know how ALL the CSi passwords work). So we reset the unit to reload the firmware, but the serial number didn't match. We conclude that the unit in the box has a different serial number than than marked on the box.
So, my question is, did anyone have this unit; 938357?
