Introduction
Overview
The US2000A is a light-industrial grade serial RS232 / RS485 to Ethernet converter which can
be used to connect any standard RS232 or RS485 serial device to a computer over a standard
Ethernet network.
It has a strong aluminum housing with screw mounting holes for easy installation which makes
it ideal for most factory environments and other commercial facilities.
This converter is designed around the ARM Cortex-M3 chipset which makes it a very reliable
converter with several advanced features and functions.
The included virtual COM software will allow you to create two serial ports, one RS232 and
one RS485 which can be used individually at the same time.
The parameters of the adapter can be configured by a web-browser, through the serial port or
by using the downloadable configuration software.
