MOXA NPort 5110-1 Port Serial Device Server, 10/100 Ethernet, RS232, DB9 Male
Quick take
The MOXA NPort 5110-1 turns a single RS232 serial device (DB9 male) into a network-accessible endpoint using standard TCP/IP over 10/100 Ethernet. It is a strong fit for buyers who want dependable COM port or TTY-style access via real drivers on Windows, Linux, and macOS, with multiple configuration paths (Telnet, web browser, or a Windows utility). The main caveat is that it is a one-port RS232 device server, so multi-device or non-RS232 needs require looking at other options.
Pros and cons
Pros
- One-port RS232 (DB9 male) serial-to-Ethernet bridge for standard TCP/IP networking.
- “Real” COM and TTY drivers for Windows, Linux, and macOS, including COM port emulation.
- Multiple configuration methods, including Telnet, a web browser, and a Windows utility.
- SNMP MIB-II support for network management.
- Buyer feedback consistently mentions reliable long-term operation and stable setup.
Cons
- Only supports one serial port, so it may not cover multi-device deployments.
- Requires the right serial side (RS232 with DB9 male) for your existing equipment.
- Ethernet devices servers are configuration-heavy, and setup may still take time in complex environments.
What buyers think
Across available buyer review snippets, the dominant themes are straightforward configuration and stable driver-based access. Multiple reports highlight quick setup using the provided Windows utility and a COM port experience that works well for real-time or operational use cases. Buyers also describe the hardware as well-built and reliable over time, with particular emphasis on avoiding connection or timeout issues that can occur with less robust USB serial approaches. Overall buyer-review evidence points to consistent day-to-day reliability, though the sample is limited to the included snippets rather than a full consensus review set.
Who this is best for
- Teams bridging legacy RS232 equipment onto a network without replacing the serial device itself.
- Buyers who rely on COM/TTY access from host systems and prefer driver-based integration rather than “raw” TCP only.
- Operations that need manageable deployment using Telnet, a web browser, and a Windows configuration tool.
- Network-managed environments where SNMP MIB-II visibility can matter.
Pros and cons in plain terms
Strengths you will notice
- Driver support that fits common workflows: The device server is positioned for real COM and TTY driver use across Windows, Linux, and macOS, which is useful if your applications expect serial ports.
- Versatile configuration: You can configure it through Telnet, a web browser, or Moxa’s Windows utility, which helps when you support mixed IT setups.
- Built for reliability: Buyer feedback repeatedly describes trouble-free operation and long-term use, including use in remote or operational contexts.
- Network management support: SNMP MIB-II can help with monitoring and inventorying in network environments.
Tradeoffs to consider before buying
- It is a single-port RS232 device server: If you need more than one serial connection per unit, you will likely need additional device servers or a multi-port model.
- Your serial gear must match: The RS232 side is specifically addressed via the DB9 male connection, so confirm cabling and signaling compatibility with your equipment.
- Setup complexity varies by environment: Even when setup is straightforward, network routing, VPNs, and firewall rules can affect connectivity, so plan time for integration testing.
Setup and day-to-day usability
This device server is designed so you can configure it through a few common interfaces, which is helpful when you support different computer networks and admin preferences. Buyers highlight that using the Windows utility and getting COM port emulation working can be a quick path to usable connectivity, and that stable behavior matters when the host application needs consistent serial access. For larger deployments, the combination of standard TCP/IP operation and SNMP MIB-II support also makes it easier to fit into typical network workflows.

Is the MOXA NPort 5110-1 worth it?
If you have RS232 devices with a DB9 male connection and you want a reliable serial-to-Ethernet bridge that integrates cleanly with COM/TTY driver workflows, this is a practical option. It also makes sense if you value configuration flexibility (Telnet, web, Windows utility) and network management visibility (SNMP MIB-II). The purchase is not as straightforward if you need more than one serial port per unit or if your equipment uses a different serial standard.
Alternatives to consider (based on common buyer priorities)
- If you need multiple serial connections: look for a multi-port serial device server so you can reduce hardware sprawl.
- If your applications do not need COM/TTY emulation: some device server approaches may focus more on raw TCP/UDP, which can be simpler depending on your software.
- If you are budget constrained: compare features around driver quality, configuration options, and management support, since those factors can affect long-term operational friction.
FAQ
Does the MOXA NPort 5110-1 provide real COM port access?
It is designed with COM and TTY driver support for Windows, Linux, and macOS, enabling driver-based serial port emulation so applications can communicate as if they are using a local serial port.
What serial connector does it use?
It uses an RS232 interface with a DB9 male connection for the serial side.
How can you configure the device server?
Configuration options include Telnet, a web browser, and a Windows utility intended for setting up one or multiple device servers.
Is SNMP supported?
Yes, SNMP MIB-II is included for network management use cases.
Is this a good choice for remote or VPN-connected networks?
It is built for standard TCP/IP networking, and buyer feedback describes successful use in remote operational contexts. Connectivity still depends on your network routing and firewall/VPN configuration, so validate integration in your environment.
How many serial ports does it support?
The NPort 5110-1 is a one-port model, intended for a single RS232 serial device connection.
Who should avoid this device server?
Buyers who need multiple serial ports per unit, or those whose devices do not use RS232 over a DB9 male connection, will likely have a better match in other models or categories.
