The Moxa NPort 5410 is a 4-port RS-232 serial device server that brings multiple RS-232 devices onto Ethernet without the footprint and complexity of a full rackmount unit. It’s a practical middle ground when you’ve outgrown single/dual-port options but don’t need 8 or 16 ports.

Why We Love This Product

• Four RS-232 ports—ideal for small clusters of serial devices in a panel or cabinet
• Keeps legacy RS-232 equipment useful by moving connectivity onto IP networks
• Cleaner and more scalable than stacking multiple single-port adapters
• Good fit for compact installations that still need multi-port capability

How Our Customers Use It

• Connecting 2–4 RS-232 devices in a control cabinet to a networked monitoring system
• Modernising small sites while keeping existing serial instruments and controllers
• Replacing ad-hoc serial extender setups with a more manageable serial-to-IP approach
• Remote servicing workflows where serial ports need to be reachable over the network

Choosing Tips

• Choose NPort 5410 when you need multiple RS-232 ports but don’t want a rackmount form factor
• If you need RS-232/422/485 flexibility (not just RS-232), choose a model that supports those serial standards
• If you’re planning for higher port counts in a rack, a rackmount 8-port or 16-port unit will scale more cleanly
