[USB-501] USB to RS-232C Converter Compact HuMANDATA LTD.

Overview

USB-501 is a USB to RS232C converter that isolated with 2500VDC between RS232C and a USB port. It supports High Speed baud rates of up to 1Mbps. The device driver uses the standard CDC (Communication Device Class) driver included in the OS.

The properties of data bits length, stop bits and parity check are fixed. Those settings are available for the high-function type product USB-511.
