The NPort 5110 from Moxa is a Device-Server with an RS-232 interface, integrating serial devices such as measuring instruments, terminals or controls into an Ethernet network. The device serves as a bridge between legacy serial peripherals and modern IP-based networks, enabling communication via TCP/IP protocols. Thanks to its compact metal housing and robust construction, it is particularly suitable for industrial applications where reliability and mechanical stability are required. The operating temperature of 0 to 55 °C makes the NPort 5110 suitable for locations that are not subject to extreme climatic conditions.

Applications

The NPort 5110 is typically used in industrial automation environments where existing serial devices such as card readers, payment terminals, sensors or industrial controls need to be integrated into a network. It enables remote control and monitoring of these devices over a LAN or WAN without replacing the existing hardware. Integration into IT systems is achieved via standardised network protocols, ensuring compatibility with various software solutions.

Functions and Equipment in Detail

The device features an RS-232 connection with a DB9 male connector, intended for connecting to serial end devices. The serial interface supports a baud rate from 110 bps to 230.4 kbps, allowing even high-speed devices to be connected. Configuration of serial parameters such as data bits (5–8), stop bits (1, 1.5, 2) and parity (none, even, odd, Space, Mark) is performed via the web interface, Telnet or a serial console. Flow control can be managed via RTS/CTS, DTR/DSR or XON/XOFF, ensuring stable and error-free data transmission.

Technology Explained Simply

The NPort 5110 features an Ethernet interface with 10/100BaseT(X), implemented via an RJ45 connector. The integrated magnetic isolation of 1.5 kV protects the device from voltage surges and electrical interference, which is particularly important in industrial environments. Network communication occurs via TCP/IP protocols, supporting various operating modes such as TCP Server/Client, UDP, Ethernet Modem, Reverse Telnet and Pair Connection. This versatility allows adaptation to different software requirements and network architectures.

Compatibility and Accessories

The NPort 5110 is equipped with Real COM drivers for Windows (95 to 11, Server 2000 to 2022) and Real TTY drivers for Linux (kernel 2.4 to 6.x) as well as macOS (10.1x to 14). These drivers allow existing software developed for serial COM ports to be used without modifications. Additionally, drivers for UNIX derivatives (e.g. SCO, QNX, Solaris) and virtual platforms such as VMware ESXi, Fusion and Parallels Desktop are available. Configuration is performed via web interface, Telnet or a serial console, with a Windows utility also provided.

Mounting and Installation

The device can be mounted on a desktop, on a wall, or optionally on a DIN rail. Dimensions are 75.2 x 80 x 22 mm (with mounting) or 52 x 80 x 22 mm (without mounting). Power supply is via a power connector with an input voltage of 12–48 VDC. At 12 VDC, the power consumption is 128.7 mA. Installation is simple, as no special tools or additional components are required.

Operational Advantages

The NPort 5110 offers high operational reliability thanks to integrated magnetic isolation and robust construction. The 5-year manufacturer's warranty underscores the device's reliability. The MTBF (Mean Time Between Failures) is 3,126,448 hours according to Telcordia TR/SR standard, indicating a long service life and low failure probability. Support for SNMPv1 and MIB-II (RFC1213, RFC1317) enables network monitoring and management, allowing faults to be detected early. Authentication is performed via a local database with password, providing a basic security feature.

Certifications

The device complies with safety standards EN/IEC 62368-1 and UL 60950-1. EMC compliance is according to EN 55032/35, and EMI and EMS requirements (e.g. ESD, Surge, EFT, CS, RS, PFMF) are fulfilled. Certification according to FCC Part 15B Class A and CISPR 32 ensures functionality in electromagnetically demanding environments.

Environmental Conditions

The NPort 5110 can be operated at an operating temperature of 0 to 55 °C and a relative humidity of 5–95 % (non-condensing). Storage temperature ranges from -40 to 75 °C, allowing flexible storage.
