The Moxa NPort 5150 (EU) is an industrial device server that integrates serial devices over Ethernet into an IP-based network. It enables direct access from PC software to serial end devices such as card readers or payment terminals from any network location. The compact design makes it particularly suitable for use in limited installation environments where space and reliability are prioritized. The server features a serial port supporting RS-232, RS-422, and RS-485, and provides a DB9 interface. Integration is achieved via a standard TCP/IP interface that supports various operating modes to flexibly respond to different application scenarios.

Applications

The NPort 5150 (EU) is used in industrial and commercial environments where serial devices must be accessed over a network. Typical applications include networking POS terminals, access control systems, sensors, or measuring devices that communicate via serial interfaces. The devices are designed for use in environments with high demands on stability and reliability, such as retail, logistics, or production facilities.

Functions and Equipment in Detail

The server provides a real COM/TTY driver for operating systems such as Windows and Linux, enabling transparent communication between the application and the serial device. Configuration is performed via a Windows utility that simplifies the setup of multiple device servers. Additionally, the server can be configured via Telnet or a web browser, enabling flexible remote maintenance. For network management, SNMP MIB-II is integrated, facilitating integration into existing network management systems.

Technology Explained Simply

The integrated 15 kV ESD protection safeguards serial signals against electrostatic discharges, increasing the device’s robustness in industrial environments. For RS-485 ports, an adjustable termination resistor is available, optimizing signal quality over long cable runs. The TCP/IP interface enables communication over Ethernet, making serial devices accessible over the network without requiring physical connections to each device. Support for multiple operating modes allows adaptation to different communication requirements, such as server-client mode or transparent mode.

Compatibility and Accessories

The NPort 5150 (EU) is compatible with Windows and Linux operating systems, with the real COM/TTY driver enabling integration into existing software solutions. The serial interface supports RS-232, RS-422, and RS-485 standards, ensuring broad applicability. Network connectivity is via Ethernet, making integration into existing LAN infrastructures straightforward.

Installation and Mounting

Installation involves connecting the serial DB9 interface to the device to be networked and connecting Ethernet to the network. Configuration can be performed locally via the Windows utility or remotely via Telnet and web browser. Setup requires no special tools, and operation is based on standardized protocols. The compact design allows flexible mounting, for example in enclosures or on walls.

Operational Advantages

Operation of the NPort 5150 (EU) enables centralized control and monitoring of serial devices over the network. Remote configuration and maintenance reduce maintenance effort, and the ESD protection function increases reliability in industrial environments. Support for SNMP MIB-II enables integration into existing network management systems, simplifying monitoring and fault diagnosis. The combination of compact design and robust features makes the server a reliable solution for networking serial devices.
