Just helped in the little 'Büdchen' (kiosk comes close, but in reality it is more of an little super market) around the corner to Update the firmware of a money bill verifier and counter... As there are new 50 Euro bills.

God. Serial to USB. After running installer and starting firmware update, the owner was a bit frightened as it took so long....

Setup. 30 secs. Firmware. 6 Minutes. XD
