Overview

 USB-039 is a 2 channel USB to RS485/RS422 converter that isolated between each RS-485/422 serial port and a USB port. You can use 2 channels of RS-485/422 serial port from a USB port. Those 2 channels are isolated independently from USB side.
USB-039 has the dip switch to enable and disable the built-in 120 ohm terminal resistor. This is designed around the high performance industry proven FTDI chipset.
