4. Setup
This section guides you through the physical installation and initial network configuration of your NPort 5110A.
4.1 Physical Installation
- Mounting: The NPort 5110A can be wall-mounted using the integrated mounting brackets. Secure the device in a stable location using appropriate screws.
- Power Connection: Connect a 12-48 VDC power source to the device's power input terminal. Ensure the power supply meets the specified voltage range. The device consumes only 1W of power.
- Ethernet Connection: Connect an Ethernet cable from your network switch or router to the 10/100M Ethernet port on the NPort 5110A. Verify the Link LED illuminates.
- Serial Device Connection: Connect your RS-232 serial device to the DB9 male serial port (Port 1) on the NPort 5110A.
4.2 Initial Network Configuration
The NPort 5110A supports speedy 3-step web-based configuration.
- Connect to Network: Ensure the NPort 5110A is connected to your local area network (LAN) as described in section 4.1.
- Discover Device: Use Moxa's NPort Windows Driver Manager or a similar utility to discover the NPort 5110A on your network and identify its IP address. Alternatively, if your network has a DHCP server, the device may obtain an IP address automatically.
- Access Web Console: Open a web browser and enter the NPort 5110A's IP address in the address bar. Log in using the default username and password (refer to the Quick Installation Guide or Moxa's website for default credentials).
- Configure Settings: Within the web console, configure the serial port settings (baud rate, data bits, parity, stop bits, flow control) to match your connected serial device. Set the desired operating mode (e.g., Real COM, TCP Server, TCP Client, UDP).
For detailed configuration options, refer to the comprehensive user manual available on the Moxa website.
5. Operating Instructions
The NPort 5110A offers various operating modes to suit different application requirements.
5.1 Standard TCP/IP Interface and Operation Modes
The device supports standard TCP/IP interfaces and versatile TCP and UDP operation modes, including:
- Real COM/TTY Mode: Allows your PC to access the serial device as if it were directly connected to a local COM port. Real COM/TTY drivers are available for Windows and Linux.
- TCP Server Mode: The NPort 5110A listens for incoming TCP connections from host applications. Up to 8 TCP hosts can connect simultaneously.
- TCP Client Mode: The NPort 5110A actively establishes a TCP connection to a specified host IP address and port.
- UDP Mode: Data is transmitted and received using UDP packets, suitable for broadcast or multicast applications.
5.2 COM Port Grouping and UDP Multicast
The NPort 5110A supports COM port grouping and UDP multicast applications, enhancing flexibility for specific industrial communication scenarios. Refer to the advanced configuration guide for details on setting up these features.
6. Maintenance

- Environmental Conditions: Ensure the device operates within its specified temperature range (0 to 60°C) and humidity levels. Avoid exposing the device to extreme conditions.
- Cable Integrity: Regularly inspect all connected cables (power, Ethernet, serial) for any signs of damage or wear. Replace damaged cables immediately.
7. Troubleshooting
This section provides solutions to common issues you might encounter with your NPort 5110A.
7.1 LED Indicator Status
- Ready LED Off: Check power connection. Ensure the 12-48 VDC power supply is correctly connected and functional.
- Link LED Off: Verify the Ethernet cable is securely connected to both the NPort and the network device. Check the network switch/router status.
- Tx/Rx LED Not Flashing: Ensure the serial device is correctly connected and powered on. Verify serial port settings (baud rate, etc.) match the connected device. Check if the host application is attempting to communicate.
7.2 Network Connectivity Issues
- Cannot Access Web Console: Double-check the IP address. Ensure your PC is on the same subnet as the NPort. Temporarily disable firewall on your PC for testing.
- Device Not Discovered: Ensure the NPort is powered on and connected to the network. Use Moxa's NPort Search Utility to locate the device.
7.3 Serial Communication Problems
- Data Corruption or No Data: Verify that the serial port settings (baud rate, data bits, parity, stop bits, flow control) on the NPort match those of the connected serial device and the host application.
- Incorrect Cable: Ensure you are using the correct RS-232 cable type (straight-through or null modem) as required by your serial device.
If problems persist, consult the full user manual on the Moxa website or contact Moxa technical support.
