Serial-to-Ethernet Device Servers

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 

The Moxa MiiNe is a small but powerful ARM-based serial-to-Ethernet 
SoC with RAM and Flash embedded. With the MiiNe inside, the 
NPort® 5110A series becomes the world’s only device server with 
power consumption less than 1 W. The NPort® 5100A series saves 
at least 50% on power consumption compared to existing solutions 

The NPort® 5100A’s 3-step web-based configuration tool is 
straightforward and user-friendly. The NPort® 5100A’s web console 
guides users through 3 simple configuration steps that are necessary 
to activate the serial-to-Ethernet application. With this speedy 3-step 
web-based configuration, a user only needs to spend an average of 

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 

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 

device servers are ultra lean, ruggedized, and user friendly, making 
simple and reliable serial to Ethernet solutions possible.

on the market, helping engineers meet 
the tough environmental compliance 
challenges found in today’s industrial 
environments.

30 seconds to complete the NPort® 
settings and enable the application, 
saving a great amount of time and 
effort.

e-mail 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 provides a robust serial-
to-Ethernet solution that can protect 
electrical devices from voltage spikes and 
withstand electrically noisy environmental 
conditions.
