The Moxa NPort 6150 is a 1-port serial device server that brings RS-232/422/485 devices onto an IP network, with a focus on more secure deployment. It’s a clean way to keep legacy serial equipment useful in modern OT networks—without relying on fragile workarounds.

Why We Love This Product

• Connects a single serial device (RS-232/422/485) to Ethernet for remote access and integration
• “Secure device server” positioning makes it a better fit for managed industrial networks
• Ideal when you need flexibility across serial standards without swapping hardware
• Great for gradual modernisation—keep the device, upgrade the connectivity

How Our Customers Use It

• Putting legacy serial instruments and controllers onto Ethernet without replacing them
• Remote monitoring and maintenance workflows for serial-based assets
• Serial-to-IP connectivity in utilities, transport, and industrial automation networks
• Centralising access to serial endpoints from a control room or secure OT network segment

Choosing Tips

• Choose NPort 6150 when you need a single-port device server with RS-232/422/485 flexibility and a security-focused deployment
• If you only need RS-232 and want a simpler device server, a dedicated RS-232 model can be enough
• If you have multiple serial devices in the same rack or cabinet, a multi-port rackmount NPort will reduce clutter and simplify management
