The NPort 5610-16 from Moxa is an industrial-grade Device-Server with 16 serial RS-232 ports, designed for use in central, rack-mounted network infrastructures. The device enables the integration of serial devices into IP-based networks and is particularly suitable for applications in industrial automation, utility companies, and medical facilities. The serial interfaces are implemented as 8-pin RJ45 connectors, ensuring a standardized and robust connection. The metal housing is designed for installation in 19-inch racks, providing mechanical stability and protection against environmental influences.

Applications

The NPort 5610-16 is used in environments where serial devices such as measuring instruments, sensors, controls, or medical equipment need to be accessed over a network. Support for protocols such as TCP/IP, UDP, RFC2217, and SNMPv3 enables flexible integration into existing networks. Broad operating system compatibility, including Windows, Linux, macOS, Android, and VMware platforms, facilitates use in heterogeneous IT environments. Medical certification according to EN 60601-1-2:2007 makes the device suitable for use in hospitals and medical facilities.

Functions and Features in Detail

The device features 16 independent RS-232 interfaces that can be configured in various operating modes, including Real COM, TCP Server, TCP Client, UDP, Ethernet Modem, Pair Connection, Reverse Telnet, and RFC2217. The baud rate can be set between 50 and 921.600 bps, with flexible configuration options for data bits (5–8), stop bits (1, 1.5, 2), and parity types (none, even, odd, Space, Mark). Flow control supports RTS/CTS, DTR/DSR, and XON/XOFF. The serial signals include TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND. Configuration is performed via a web interface (HTTP/HTTPS), Telnet console, or Windows utility software.

Technology Explained Simply

The Ethernet interface supports 10/100BaseT(X) via an RJ45 connector and provides magnetic isolation of 1.5 kV, protecting against network disturbances and voltage surges. Network functions include standard protocols such as ARP, ICMP, DNS, DHCP Client, BOOTP, SMTP, SNMPv1/v2c, TCP/IP, UDP, LLDP, and RFC2217. Time synchronization is achieved via SNTP. Security features include authentication via a local database, encryption using AES-128, RSA-1024, SHA-1, and SHA-256, as well as support for HTTPS (TLS 1.2) and SNMPv3. An integrated watchdog timer ensures automatic restart in case of system failure, enhancing operational reliability.

Compatibility and Accessories

The NPort 5610-16 is compatible with a wide range of operating systems, including Windows 95 to 11, Server 2003 to 2022, Linux Kernel 2.4.x to 6.x, macOS 10.12–10.15 and 11.x, Android API from 3.1.x, as well as VMware ESXi, Fusion, and Parallels. Driver support enables seamless integration into existing systems. The devices are designed for industrial environments and comply with EMC standards such as EN 55032/35, CISPR 32, FCC Part 15B Class A, as well as EMS standards according to IEC 61000-4-2 to -4-11. Safety certification is performed according to UL 62368-1.

Mounting and Installation

The device is mounted in a 19-inch rack and features rack ears for installation. Dimensions are 480 mm (with rack ears) or 440 mm (without) in width, 45 mm in depth, and 198 mm in height. Weight is 2,490 g. Operation is performed via an LCD display and configuration buttons on the device. Power supply is 100 to 240 VAC (47–63 Hz), with power consumption of 141 mA @ 100 VAC.

Operational Advantages

The NPort 5610-16 offers high reliability with an MTBF of 680,154 hours (according to MIL-HDBK-217F). Operating temperature ranges from 0 to 60 °C, and storage temperature from -20 to 70 °C. Humidity levels between 5 and 95 % are permitted, provided no condensation occurs. Integrated security functions and support for encrypted communication (HTTPS, TLS 1.2) enhance data security. The 5-year warranty underscores the quality and longevity of the device.
