The NPort 5400 Series is a flexible and reliable device server solution designed to connect up to four serial devices to an Ethernet network. Supporting RS-232, RS-422, and RS-485 interfaces, the device allows independent configuration for each serial port in modes such as TCP Server, TCP Client, or UDP. This ensures maximum adaptability for various field applications.

Equipped with a user-friendly LCD panel, configuration is simple and quick. Models with extended temperature support from -40 to 75 °C are available for harsh environments. The dual power input design ensures redundancy, and adjustable termination and pull high/low resistors for RS-485 offer added signal integrity. The series meets comprehensive EMC, safety, maritime, and medical standards depending on model.
