The Moxa NPort 5110 is a 1-port RS-232 device server that connects a single RS-232 device to Ethernet for reliable network access. With a 0 to 55°C operating temperature range, it’s a solid fit for standard indoor industrial environments where you want simple RS-232-to-IP connectivity without extra features.

Why We Love This Product

• Single-port RS-232 device server—simple, focused, and easy to deploy
• 0 to 55°C operating range covers most cabinet and equipment room installs
• Great for retrofits where one serial device needs Ethernet access
• Avoids overbuying when RS-422/485 support isn’t required

How Our Customers Use It

• Connecting a single RS-232 endpoint into SCADA or monitoring systems over IP
• Remote diagnostics for serial-connected equipment to reduce site visits
• Incremental upgrades where replacing legacy serial gear isn’t justified
• Standardising RS-232 connectivity across multiple small sites

Choosing Tips

• Choose NPort 5110 when your device is RS-232 only and a 0 to 55°C rating fits your environment
• If you need the higher 0 to 60°C rating, choose the NPort 5110A variant
• If you need RS-422/485 flexibility, step up to the NPort 5150/5150A models
