The Moxa NPort 5150AI-M12-T is a Device-Server from the NPort 5000AI-M12 series, specifically developed for use in rail applications, whether on rolling stock or in trackside installations. The device connects serial devices via Ethernet and enables their integration into existing network infrastructures. It features a robust metal housing with protection rating IP40, protecting against dust and splashing water, and is equipped with vibration-resistant M12 connectors to meet the demands of harsh environments. Compliance with standards EN 50155 (mandatory tests) and EN 50121-4 ensures reliability and safety in the rail sector.

Applications include networking industrial controls, sensors, operator panels, and other serial devices in railway vehicles, stations, or signaling systems. The devices are designed for use in environments with mechanical stress, such as vibrations and shocks, which is confirmed by certification according to IEC 60068-2-6 for vibrations. The operating temperature range is wide-temp, from -40 to 75 °C, enabling use in extreme climatic conditions.

Functions and equipment in detail include a serial connection with DB9 male for connection to RS-232/422/485 devices. The baud rate can be set between 50 and 921.600 bps, with data bits (5–8), stop bits (1, 1.5, 2), and parity types (none, even, odd, Space, Mark) configurable flexibly. Flow control is achieved via RTS/CTS, DTR/DSR, or XON/XOFF. For RS-485, data direction is automatically controlled via ADDC (Automatic Data Direction Control). Galvanic isolation is 2 kV, providing high immunity to interference and protection against voltage surges.

Technology explained simply shows that the device features an Ethernet port with M12 D-coded (female, 4-pin), designed for secure and robust connections in industrial environments. Network configuration is possible via Web (HTTP/HTTPS), Windows Utility, Telnet, DSU, or MCC. Supported protocols include TCP/IP, UDP, SNMPv1/v2c/v3, DHCP, BOOTP, DNS, LLDP, SMTP, ICMP. IGMP filtering (v1/v2) enables control of multicast traffic. Security features include HTTPS, AES-128 encryption, and SNMPv3 to protect access to the device. Remote access and SNMP monitoring support monitoring and remote maintenance in modern networks.

Compatibility and accessories include Real COM/TTY drivers for various operating systems: Windows (95 to 11, Server 2000 to 2022, CE 5.0/6.0), Linux (Kernel 2.4–5.x), macOS (10.12–10.15), UNIX (SCO, QNX, Solaris, FreeBSD, AIX, HP-UX), as well as Android (API ≥ 3.1). Power supply is via 12–48 VDC, with compliance with EN 50155 at 24/48 VDC. Connection is via M12 A-coded (5-pin, male). Power consumption is 310 mA at 12 VDC. The MTBF (Mean Time Between Failures) according to Telcordia standard is 789,341 hours.

Mounting and installation are facilitated by the robust design and M12 connectors, ensuring a secure mechanical connection. Configuration is possible via a 3-step web configuration, simplifying setup. The devices are designed for industrial environments, with dimensions of 80 × 216.6 × 52.9 mm and a weight of 686 g. The storage temperature ranges from -40 to 85 °C, and the humidity is 5–95 % (non-condensing).

Operational advantages include high reliability, easy integration, and comprehensive security features. Support for UDP multicast and SNMP monitoring enables efficient network monitoring. Galvanic isolation protects against interference, and certifications according to EN 50155 and EN 50121-4 guarantee suitability for the rail sector. EMC and EMS certifications (EN 55032/35, FCC Part 15B, IEC 61000-4-2/-3/-4/-5/-6/-8), as well as safety certification UL 60950-1 and sustainability standards RoHS, CRoHS, WEEE, underscore quality and safe operation.

Scope of delivery includes the device NPort 5150AI-M12-T, a Quick Installation Guide, and a warranty card.
