MProg can generate unique serial numbers automatically for you (recommended). These consist of a 2 letter prefix (e.g. FT) followed by 6 alphanumeric digits generated using an algorithm based on the date and time of programming the device. It is also possible to fix the serial number to a fixed 8-digit alphanumeric string, however we do not recommend this as systems will only recognise the first instance of such a device connected to a PC.
