Overview

 USB-402 is an 8 channel USB to RS485/422 converter that isolated between each RS485/422 channel. Also, the 2 port USB connectors have a Hub function. USB Hub ports are not isolated.
USB-402 is that it 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.
