USB 2.0 RS232 Serial Converter

This internal adapter converts a USB 2.0 header into a DB9 male serial port. It lets technicians connect legacy RS232 equipment such as industrial controllers or network switches to modern motherboards. The cable fits inside the chassis for a tidy, permanent installation.

Limited by USB 2.0 and RS232 standards

The USB 2.0 interface caps throughput far below modern serial expectations. RS232 signalling restricts cable length and noise immunity compared with differential standards. Devices that need higher baud rates or longer runs will not work reliably with this adapter.
