The NPort 5210 from Moxa is a Device-Server for integrating serial RS-232 devices into IP-based networks. The compact device features two serial ports and one Ethernet port, making it ideal for connecting PLCs, measuring devices, and sensors to LAN or Internet networks. Support for various operating modes such as TCP Server, TCP Client, and UDP enables flexible communication, while the Real COM/TTY driver ensures seamless integration into various operating systems. Configuration is performed via a Windows utility, a web interface, Telnet, or a serial console, simplifying setup even in complex environments.

Applications

The NPort 5210 is designed for industrial applications, particularly in environments where serial devices need to be integrated into existing networks. Typical use cases include networking control devices in production plants, transmitting measurement data from laboratory equipment, or remote maintenance of devices over the Internet. The robust metal construction and flexible power supply ranging from 12 to 48 VDC make the device suitable for harsh environments, such as those found in manufacturing or machine building.

Functions and Features in Detail

The device offers two serial RS-232 interfaces with RJ45 connectors (8-pin). Baud rates can be set between 110 and 230400 bps, with configurable data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parity types (none, even, odd, Space, Mark). Flow control options include RTS/CTS, DTR/DSR, and XON/XOFF (RS-232 only). The Ethernet interface supports 10/100BaseT(X) and is available via an RJ45 connector. Isolation is rated at 1.5 kV, ensuring high electrical safety.

Technology Explained Simply

The NPort 5210 acts as a bridge between serial devices and IP networks. It converts serial data into IP packets and forwards them over the network. Support for protocols such as TCP/IP, UDP, Telnet, HTTP, ARP, SNMPv1, BOOTP, DHCP, ICMP, DNS, SMTP, and SNTP enables broad compatibility. SNMP MIB-II support allows integration into central network management systems, enabling monitoring and configuration of the device’s status. Operating system support ranges from Windows 11 to 95, Server 2022 to NT, Linux (kernel 2.4.x to 6.x), macOS (10.x to 14), various UNIX systems, Android (from API 3.1), and virtualization environments such as VMware ESXi, Fusion, and Parallels.

Compatibility and Accessories

The device is compatible with a wide range of operating systems and network protocols. The serial interfaces are designed for RS-232, making it particularly suitable for devices communicating via this interface. The Ethernet interface enables connection to standard LAN infrastructures. The 12–48 VDC power supply allows use with various power supply units and sources, increasing flexibility in deployment. Mounting options include desktop, wall, or optionally on a DIN rail.

Installation and Mounting

Installation involves connecting serial devices to the RJ45 ports and linking the Ethernet port to the network. Power supply is provided via a removable 3-pole screw terminal. Configuration can be performed through various interfaces, with the web interface and Windows utility being the most commonly used methods. The included quick installation guide supports the setup process.

Operational Advantages

The NPort 5210 offers high reliability with an MTBF of 381,342 hours. The robust metal housing construction and EMC certifications (EN 55032/35, CISPR 32, FCC Part 15B) ensure stable operation in electromagnetically noisy environments. ESD protection class (4 kV contact, 8 kV air) and EFT/Surge protection values (Power 1 kV, Signal 0.5–2 kV) enhance safety. Certification to UL 60950-1 and medical approval EN 60601-1-2 (only for NPort 5210) expand the application scope. Sustainability certifications RoHS, CRoHS, and WEEE demonstrate the environmental compatibility of the device. The warranty period is 5 years.
