1 Introduction
The USB-2-485 device is an USB to RS485 interface converter. It adds a standard 2-wire half-duplex RS485 bus
interface to computers with USB interface.
The USB interface of the device is USB 2.0 and USB 1.1 compatible. The RS485 interface supports all common
data rates up to 3Mbit/s. No additional power supply is required as the device is powered through the USB bus.
The software supplied with this product can be used with all versions of the Microsoft Windows operating system
that supports USB (Windows 98, Windows ME, Windows 2000, Windows XP). Windows 95 and Windows NT4.0 do
not support USB and therefore are not supported. A virtual COM port driver is included, that is, the RS485 interface
can be accessed as a standard serial COM port e.g. using any terminal program like HyperTerminal (supplied with
all versions of Microsoft Windows).
