The Moxa NPort 5100A Series is a rugged, compact, and energy-efficient serial-to-Ethernet device server family that enables RS-232/422/485 connectivity over IP networks. With built-in surge protection on serial, Ethernet, and power lines, as well as ultra-low power consumption (less than 1 W), these devices are perfect for industrial deployments where reliability and efficiency matter.

Designed around Moxa’s own MiiNe SoC, the 5100A Series supports up to 8 simultaneous TCP connections, comes with flexible operation modes (TCP, UDP, COM, RFC2217), and supports major OS platforms. The fast 3-step web-based setup simplifies installation and configuration significantly.
