The USB485 is an isolated USB-RS422/485 converter.
This product is ideal for laptops which do not have a physical serial port and cannot be used with a conventional interface converter.
Drivers are included (on an 80mm CD) to create a virtual COM port in the operating system.
The USB485 is unique in the market in that it has a world-unique device ID which ensures that it appears under the same COM port number regardless of which USB port on a particular PC it is plugged into. This simplifies application software configuration.
