Moxa NPort 5100A Description
The Moxa NPort 5100A is a compact and rugged serial device server that allows traditional serial equipment (like PLCs, HMIs, meters, sensors, card readers or legacy devices) to communicate seamlessly over IP-based Ethernet networks. It embeds advanced networking protocols and multiple operation modes (TCP/UDP/Real COM) to cater to different application requirements. Moxa
With surge protection integrated on the serial interface, Ethernet port, and power lines, the NPort 5100A offers additional reliability in electrically noisy industrial environments. Its 3-step web-based configuration significantly reduces setup time, while the support for Real COM/TTY drivers ensures compatibility with existing software on Windows, Linux, and macOS systems. Moxa
The device’s small footprint makes it ideal for control cabinets, machine networking, or placement in constrained spaces — and flexible mounting options (desktop, DIN-rail, wall) help adapt to various installation requirements. Its low power consumption and robust networking features provide an efficient and cost-effective solution for integrating serial equipment into modern IP networks. Moxa
