MOXA NPort 5110A Serial to Ethernet Device Server
September 4, 2025

MOXA NPort 5110A Introduction
The NPort® 5100A device servers are designed to make serial devices network-ready in an instant and give your PC software direct access to serial devices from anywhere on the network. The NPort® 5100A device servers are ultra-lean, ruggedized, and user-friendly, making simple and reliable serial-to-Ethernet solutions possible.
Easy to Troubleshoot
NPort® 5100A device servers support SNMP, which can be used to monitor all units over Ethernet. Each unit can be configured to send trap messages automatically to the SNMP manager when user-defined errors are encountered. For users who do not use SNMP Manager, an email alert can be sent instead. Users can define the trigger for the alerts using Moxa’s Windows utility, or the web console. For example, alerts can be triggered by a warm start, a cold start, or a password change.
Surge Protection for Serial, Ethernet, and Power
Surge, which is typically caused by high voltages that result from switching and lightning transients, is a common threat to all electrical devices. Moxa’s leading-edge surge immunity solution, which is applied to the NPort® 5100A’s serial, power, and Ethernet lines, is tested and proven compliant with IEC 61000-4-5. This state-of-the-art surge protection provides a robust serial-to-Ethernet solution that can protect electrical devices from voltage spikes and withstand electrically noisy environmental conditions.
