USB-485\4, 4-Port USB to RS-485 Converter, Universal EURO 240Vac
USB device for measuring device control via the serial bus with 4 ports, RS485/RS422 - The USB-485/4 interface provides an asynchronous serial port instead of a USB port to enable communication with devices equipped with the RS-485 and RS-422 interfaces. The USB-485/4 port can be used as a standard serial port within applications, including RTS/CTS hardware handshake lines, and NI serial ports appear as standard COM ports for compatibility with programs that use serial communication.
