The Moxa NPort 5110 (EU) is an industrial Device-Server with a serial port, specifically developed for integrating RS-232 devices into an Ethernet network. It enables access to serial end devices such as card readers or payment terminals over an IP-based LAN, thereby simplifying communication between legacy hardware and modern network systems. The compact design makes it particularly suitable for installation in existing infrastructures, where space and reliability are prioritized.

Applications

The NPort 5110 (EU) is used to integrate serial devices with an RS-232 interface into an Ethernet network. This is particularly relevant in industrial environments, retail, or administrative facilities where older devices are to be continued in use without requiring comprehensive hardware modernization. The direct network connection enables centralized control and monitoring of the devices over the network.

Functions and Equipment in Detail

The Device-Server features a serial port with RS-232 interface, implemented via a DB9 connector. This port enables connection to standard serial devices. Network communication is achieved through an Ethernet connector, allowing integration into existing LAN infrastructures. The device can be configured via various methods: via Telnet, through a web browser, or using a Windows utility program, which also supports simultaneous configuration of multiple device servers.

Technology Explained Simply

The NPort 5110 (EU) operates as a bridge between serial devices and the network. It simulates a serial interface on the PC via Real COM/TTY drivers, available under Windows and Linux. This allows software on the PC to communicate directly with the serial device as if it were locally connected. Communication occurs over TCP/IP, making the devices accessible over the network. The integrated ESD protection of 15 kV safeguards the serial signals against electrostatic discharges, enhancing reliability in industrial environments.

Compatibility and Accessories

The Device-Server is compatible with operating systems such as Windows and Linux, with driver support for the Real COM/TTY interface guaranteed. Network management functions are based on SNMP MIB-II, enabling integration into existing network monitoring systems. Configuration is performed using standardized protocols, so no special tools are required.

Mounting and Installation

Installation involves connecting the serial device to the DB9 port and linking the Device-Server to the network via Ethernet. Configuration can be done via a web browser or Telnet, where settings such as IP address, port number, and operating mode can be adjusted. The Windows utility program enables centralized management of multiple NPort devices.

Advantages in Operation

Using the NPort 5110 (EU) reduces the need for additional hardware or software adapters. Direct network integration allows flexible placement of serial devices, as they no longer need to be directly connected to the PC. Support for SNMP MIB-II enables easy integration into network management systems, making device monitoring and maintenance more efficient. The integrated ESD protection increases operational safety in environments with high electrostatic loads.
