MOXA NPort 5250 2-Port RS-232/422/485 Serial Device Server
The MOXA NPort 5250 is a 2-port serial device server designed to connect RS-232, RS-422 and RS-485 serial equipment to a standard Ethernet network. It provides a practical way to bring legacy or industrial serial devices onto IP-based networks, allowing connected equipment to be accessed and managed remotely through network-based communication.
With support for two serial ports and 10/100 Mbps Ethernet connectivity, the NPort 5250 is suitable for applications where PLCs, meters, controllers, terminals, industrial instruments and other serial devices need to communicate across an Ethernet infrastructure. Its support for TCP Server, TCP Client and UDP communication modes allows it to integrate with different network-based serial communication architectures.

Reliable Serial-to-Ethernet Connectivity
The NPort 5250 is designed for environments where existing serial equipment needs to communicate through an Ethernet network. Instead of replacing operational RS-232, RS-422 or RS-485 equipment, the device server provides a network interface between the serial device and Ethernet infrastructure.
For RS-485 installations, the supported automatic data-direction control can simplify half-duplex communication. The device also supports configurable serial communication parameters, allowing it to work with a wide range of industrial and legacy serial equipment.
Applications
- Industrial automation and control systems
- PLC and controller network integration
- Remote monitoring of serial instruments
- Factory and production-line communication
- Building automation and monitoring systems
- POS, access-control and terminal equipment
- Legacy serial device integration with Ethernet networks
- Remote serial console and device management
Compatibility Considerations
The NPort 5250 is intended for serial equipment using RS-232, RS-422 or RS-485 communication. The required serial mode, wiring, baud rate, parity, flow control and other parameters should be matched with the connected equipment. For RS-485 networks, termination and biasing should also be configured according to the network topology.
Because the NPort 5250 is an older-generation device-server model, buyers should verify the exact hardware revision, condition, included accessories and software/driver requirements when purchasing legacy or refurbished units. Do not confuse the original NPort 5250 with the newer NPort 5250A series, which has updated specifications and security features.
