The Moxa NPort 5410 is a Device-Server with four serial RS-232 interfaces, specifically designed for integrating serial devices into Ethernet networks. It enables the connection of RS-232 devices such as measuring instruments, sensors, or industrial controls to IP-based networks, allowing central monitoring and control over the network. The device is designed for use in industrial automation environments, where reliability, security, and flexible configuration are important. Local operation is performed via an LCD display with buttons, enabling direct configuration and status indication. The serial ports are equipped with DB9 connectors and support a variety of operating modes, including Real COM, TCP Server, TCP Client, UDP, Ethernet Modem, Pair Connection, and Reverse Telnet. The baud rate can be set between 50 and 921600 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 is supported via RTS/CTS and DTR/DSR, with all relevant signals (TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND) supported.

Applications include industrial control systems, building automation, medical device connectivity, and marine applications. Certification according to DNV makes the NPort 5410 suitable for use in shipping, while medical certification according to EN 60601-1-2 Class B and EN 55011 enables use in medical facilities. The Ethernet interface consists of a 10/100BaseT(X) RJ45 port with magnetic isolation of 1.5 kV, ensuring high immunity to interference and protection against voltage surges. Network functions include protocols such as ARP, BOOTP, DHCP Client, DNS, HTTP, HTTPS, ICMP, IPv4, LLDP, Rtelnet, SMTP, SNMPv1/v2c, TCP/IP, Telnet, and UDP. Management is performed via a Web Console (HTTP/HTTPS), Telnet Console, or a Windows Utility. Time synchronization is supported via SNTP, and driver compatibility ranges from Windows 95 to 11, Server 2000 to 2022, Linux Kernel 2.4.x to 6.x, macOS 10.12 to 11.x, various UNIX systems, Android from 3.1.x, and virtual machines such as VMware, Parallels, and Fusion.

Functions and equipment in detail include redundant power supply with two inputs, ensuring high availability. The operating voltage ranges from 12 to 48 VDC, with 24 VDC specified for DNV applications. Power consumption is 365 mA at 12 VDC. Power supply is provided via a removable 3-pole terminal block and a hollow connector. Reliability is enhanced by a watchdog timer, an integrated Real-Time-Clock (RTC), and an integrated buzzer that provides audible error alerts. The housing is made of metal, offering high mechanical stability and EMI shielding. Mounting options include tabletop, wall, or DIN rail (optional).

Technology explained simply shows that the NPort 5410 acts as a bridge between analog serial devices and digital networks. Serial data is converted into IP packets and transmitted over the Ethernet network. Magnetic isolation protects against electrical interference and voltage surges, which is especially important in industrial environments. The redundant power supply increases availability, as a failure of one input is compensated by the second. Local operation via LCD and buttons allows for quick diagnosis and configuration without network access.

Compatibility and accessories include support for many operating systems and network protocols. Security features include authentication via a local password database, encryption with HTTPS, AES-128, RSA-1024, SHA-1, SHA-256, and security protocols such as TLS 1.2 and SNMPv3. Certifications according to EN 55032/35, CISPR 32, FCC Class A, IEC 61000-4-2 to -4-11, UL 62368-1, DNV, and EN 60601-1-2 Class B guarantee suitability for various industries and environments.

Mounting and installation is simple, involving fixation to tabletop, wall, or DIN rail. Power supply is connected via the terminal block or hollow connector. Serial devices are connected to the four ports using DB9 connectors. Network connection is established via the RJ45 cable to the Ethernet network.

Operational advantages include high reliability, easy local operation, flexible configuration, and support for many operating systems. The redundant power supply and magnetic isolation increase stability, while certifications enable use in demanding environments. The MTBF is 880,274 hours according to Telcordia TR/SR standard, indicating high lifespan and operational safety.
