Connect legacy intelligence to modern networks.
In many industrial systems, legacy serial equipment still performs critical functions. Moxa’s NPort Industrial Device Servers provide a secure, reliable way to connect those RS-232/422/485 devices to Ethernet networks — extending their useful life while enabling data visibility at the edge.
Each NPort model combines industrial-grade durability, dual Ethernet redundancy, and cyber-secure configuration options within a compact design. Whether you’re integrating sensors into SCADA, bridging PLCs to control systems, or deploying remote monitoring, NPort device servers deliver proven connectivity that’s built to last.
Industrial-Grade Advantages
Seamless serial integration
Convert RS-232/422/485 to TCP/IP without modifying existing software. Supported modes include TCP Server, TCP Client, UDP, Pair Connection, and Real COM.
Modbus Gateway capability
Translate between Modbus RTU/ASCII and Modbus TCP for easy interoperability between serial field devices and Ethernet-based SCADA or PLCs.
Cybersecurity built-in
Developed under Moxa’s IEC 62443-4-1 process, NPort supports HTTPS (TLS 1.2), SNMPv3, role-based access control, and strong encryption.
Engineered for resilience
Dual 12–48 V DC power inputs, redundant Ethernet ports, and optional 2 kV isolation ensure continuous operation in mission-critical environments.
Wide-temperature durability
With −40 to 75 °C variants and metal IP30 housings, NPort servers withstand the demands of substations, utilities, and heavy-industrial sites.

Frequently Asked Questions – Moxa NPort IA5000-G2 Series
1. What is a Moxa NPort device server used for?
Moxa NPort Industrial Device Servers allow RS-232/422/485 serial devices to communicate over Ethernet networks. They act as a bridge between legacy equipment and modern TCP/IP systems, enabling integration with SCADA, PLCs, sensors, and industrial controllers without software changes.
2. What’s new in the NPort IA5000-G2 Series compared to earlier models?
The G2 Series introduces several key improvements over the previous generation:
- Enhanced cybersecurity with HTTPS (TLS 1.2), SNMPv3, and IEC 62443-4-1 compliance
- Dual Ethernet ports for redundant or cascade networking
- Dual 12–48 V DC power inputs for power reliability
- Faster CPU performance for improved data throughput
- Wide temperature tolerance (−40 to 75 °C on “-T” models) for harsh environments
3. How does the NPort IA5000-G2 enhance network reliability?
NPort G2 models include dual Ethernet ports that can be configured in redundant mode for failover or cascade mode to simplify cabling. Combined with dual DC inputs and optional 2 kV isolation, this design ensures continuous communication even during network or power disruptions.
4. How do I configure and monitor the NPort IA5000-G2?
The NPort IA5000-G2 includes a guided quick setup wizard through Moxa’s updated Device Search Utility, making configuration faster and more intuitive. Once deployed, enhanced traffic monitoring and diagnostics tools provide real-time visibility into serial communication performance — helping you identify and resolve connectivity issues quickly and with minimal downtime.
