USB Drivers for Windows and Linux

The AMC-2120 provides USB drivers for Windows XP/Vista/7 and Linux operating system. It is easy to create two serial ports for monitoring and utilization.

Isolation and ESD protection

The AMC-2120 offers 3KV isolation protection between USB and its 2-port RS-232 interfaces.

However two ports RS-232C do not isolate each other, it also has 15KV ESD protection on all RS-232 signals and USB signals.

RS-232 performance and parameters

It supports data bit format from 7 to 8 bit setting, parity, stop bits setting, all RS-232 signals on the RS-232 interface, data bit rate transmission from 300 to 921.6 Kbps.

Wide operating temperature

For most of industrial applications are harsh environment, all AMC-2120 series provide the operating temperature from -40 to 70°C, give you a reliable solution of a USB to RS-232 converter for wide temperature application.

Wall-mount or Din-Rail solution

The AMC-2120 provides wall-mount and DIN-Rail installation solutions; allow you easily screw it by wall mount screws or mount it on the DIN-rail by DIN rail kit.
