The Moxa NPort 5150AI-M12 is a device server specifically developed for use in harsh industrial and railway environments. It enables secure integration of serial RS-232/422/485 devices into Ethernet networks. With an IP40 metal housing, M12 connectors, and certifications according to EN 50155 and EN 50121-4, it is particularly suitable for applications in the railway sector, such as in rolling stock or along railway tracks. The robust construction ensures reliable operation under demanding environmental conditions.

Applications

The NPort 5150AI-M12 is designed for industrial applications where serial devices such as sensors, controls, or measuring instruments need to be accessed via Ethernet. It is especially suitable for use in rail vehicle technology, where high mechanical stress, vibrations, and extreme temperatures occur. Certification according to EN 50155 and EN 50121-4 ensures compliance with required standards for railway technology. The integrated 2 kV isolation and surge protection protect the device from electrical disturbances.

Functions and Features in Detail

The device features a serial interface with a DB9 connector (male) and supports baud rates from 50 bps to 921.6 kbps. Configuration of data bits (5–8), stop bits (1, 1.5, 2), and parity types (none, even, odd, Space, Mark) is done via the web interface. Flow control can be managed via RTS/CTS, DTR/DSR, or XON/XOFF. Data direction control is handled automatically via ADDC. For RS-485 applications, integrated pull-up and termination resistors are provided. The network interface offers a 10/100BaseT(X) port with an M12 D-coded, 4-pin connector (female).

Technology Explained Simply

The NPort 5150AI-M12 enables communication between serial devices and Ethernet networks without requiring additional hardware or complex configurations. Web configuration is completed in three steps, ensuring quick deployment. Support for Real COM and TTY drivers ensures existing software applications can continue to be used without modifications. SNMP monitoring and email alerts enable remote monitoring of the device. Power supply is via an M12 A-coded, 5-pin connector (male) with a voltage range of 12 to 48 VDC. Power consumption is 310 mA at 12 VDC.

Compatibility and Accessories

The device is compatible with a wide range of operating systems, including Windows (95 to 11, Server 2000 to 2022), Linux (kernel 2.4.x to 5.x), macOS (10.12 to 10.15), various UNIX systems (SCO, QNX, Solaris, FreeBSD, AIX, HP-UX), and Android from API level 3.1. Network protocols include TCP/IP, UDP, SNMPv1/v2c/v3, DHCP, BOOTP, LLDP, ICMP, DNS, SMTP, and HTTPS (TLS 1.2). Authentication is performed via a local database, and encryption supports HTTPS, AES-128, RSA-1024, SHA-1, and SHA-256.
