USB-485Ui Universal baud rate USB to RS422/485 converter

The Amplicon USB-485 Ui high-performance, high-quality converters are designed and manufactured in the UK. Baud rate is selectable allowing your PC or laptop to interface to any piece of equipment with an RS422/485 port. Thanks to the new UART used in this design, absolutely any integer baud rate can be selected, not just the standard options of 19.2/38.4/115.2kbps, etc. This is ideal when interfacing to equipment that operates on non-standard data rates.
