The RS-485/422 protocol has been widely used in most of industrial equipments for serial port communication. The USB interface also has been built in the personal computer or embedded system device. RS-485/422 and USB offer better transmission speed, wide range and networking capabilities. Hence, the AMC-2320, USB to 2-port RS-422/485 converter takes the important interface and popular to be deployed in the industrial communication network and higher reliable applications.
USB Drivers for Windows and Linux
The AMC-2320 provides USB drivers for Windows XP/Vista/7/8 and Linux operating system. It is easy to create two serial ports for monitoring and utilization.
Isolation and ESD protection
The AMC-2320 offers 3KV isolation protection between USB and RS-422/485 interfaces
However two ports RS-422/485 do not isolate each other. It also has 15KV ESD protection on all RS-422/485 signals and USB signals.
Serial mode, Terminator and Biasing functions
The AMC-2320 serial converter supports RS-422, half-duplex 2-wire RS-485 and full-duplex 4-wire RS-485 modes selection, it is easy to use in the serial multi-drop networking application. There are terminators and biasing resister for tuning networking characteristics.
Wide operating temperature
For most of industrial applications are harsh environment, all AMC-2320 series provide the operating temperature from -40 to 70°C, give you a reliable solution of a USB to RS-422/485 converter for wide temperature application.
