The USB-485\/4 interface transforms your USB port into a single asynchronous serial port for communication with RS485 and RS422 devices. You can use a USB485\/4 port as a standard serial port from your application, including RTS\/CTS hardware handshake lines. NI serial interfaces also appear as standard COM ports for compatibility with programs that use serial communications.<\/p>\n

Applications and Use Cases of USB-485\/4<\/strong><\/span><\/h3>\n

The USB-485\/4 Serial Interface Device is a USB-to-RS485 interface device designed for industrial serial communication, data exchange, and multi-device networking<\/strong>. It provides reliable long-distance communication and multi-port connectivity<\/strong>, making it suitable for applications requiring robust and scalable serial communication<\/strong>.<\/p>\n

1. RS485 Serial Communication<\/strong>
USB-485\/4 enables communication with RS485-based devices, supporting reliable data transmission over long distances and in noisy environments.<\/p>\n

2. Industrial Automation Systems<\/strong>
