1.3 Driver Installation
Software setup requires installing the USB232 device driver.
The device driver allows the USB232 device to appear to the PC's application software as an additional
COM port (in addition to any existing hardware COM ports). Application software running on the PC
accesses the USB232 device as it would access a standard hardware COM port. However, actual data
transfer between the PC and the USB232 device is performed over the USB. Therefore, existing COM port
applications may be used to transfer data via the USB to the USB232-based device without modifying the
application.
All drivers are now supplied on the software CD. See the EXAR website for additional driver support for
the XR21V1410. You can reach EXAR tech support at:
