Universal Serial Bus (USB) has become the
connectivity workhorse of today’s PCs, replacing the
familiar serial ports. However, many commercial
and industrial devices still use the RS-485 interface.
To connect these devices to modern PCs, you need
a simple and reliable conversion solution. The
IC832A and IC833A offer this solution in a space
saving, USB Port powered package. Simply plug
the converter into an available USB port on your
computer or USB hub and install the drivers
supplied on CD ROM. The device will show up as
an additional COM port in the Windows Device
Manager which is fully compatible with your
Windows applications. A one meter USB cable is
included.
