is that every part start with a (relatively) unique serial number that in turn causes the (Windows) PC to create another COM port number. But it also means that each device will always appear as the same COM port, irrespective of which port you plug it into. IMO, this is far superior to other devices which will appear as a different COM port depending on which USB socket you plug it into! but if you plan on testing each device on a PC you will find this extra step quite annoying. Yes, the behaviour is great for users - but a pain if you're the developer/manufacturer trying to test them! Been there, done that! Interesting point of view. Our requirements are that the device be tied to the physical port in the way that most closely mimics the RS232 ports. Anyway the serial number can be erased using FTDI's MProg. |
