The NPort 5110 from Moxa is a compact Device-Server from the 5100 series, connecting an RS-232 interface to an Ethernet network. It enables integration of serial devices into TCP/IP-based networks, particularly in industrial automation environments where reliable communication over existing networks is required. The device features a single serial interface with a DB9 male connector and supports the RS-232 standard. Communication is achieved via a 10/100BaseT(X) RJ45 Ethernet interface, equipped with magnetic isolation of 1.5 kV to shield against electrical interference and overvoltage.

Applications

The NPort 5110 is suitable for applications where serial devices such as sensors, controllers, printers, or measuring instruments need to be integrated into a local or higher-level network. It is particularly suited for industrial environments requiring robust and low-maintenance communication solutions. Support for various operating modes including Real COM, TCP Client/Server, UDP, Reverse Telnet, Pair Connection, and Ethernet Modem enables flexible use depending on requirements. Integration into existing systems is facilitated by comprehensive operating system compatibility, covering Windows, Linux, UNIX, macOS, embedded systems, virtualization platforms, and Android from API 3.1.x.

Functions and Features in Detail

The device offers a variety of configuration options, including a Web Console (HTTP), Telnet Console, Serial Console, and a Windows Utility. Network protocols include DHCP, BOOTP, IPv4, TCP/IP, UDP, HTTP, SMTP, DNS, SNMPv1, Telnet, ARP, and ICMP. The used MIBs are RFC1213 and RFC1317, supporting network management and monitoring. The local user database with password-based authentication provides basic security functions for device access.

Technical Explanation

The serial interface supports baud rates from 110 bps to 230.4 kbps, data bits from 5 to 8, stop bits of 1, 1.5, or 2, and parity types including None, Even, Odd, Space, Mark. Flow control is managed via RTS/CTS, DTR/DSR, and XON/XOFF, ensuring stable and error-free data transmission. Power supply is via a power jack with voltage range of 12 to 48 VDC, with current consumption of 128.7 mA (at 12 VDC). The housing is made of metal, providing mechanical stability and EMI shielding.

Compatibility and Accessories

The NPort 5110 is designed for a wide range of operating systems, including modern Windows versions (95 to 11, Server 2000 to 2022), Linux kernels from 2.4.x to 6.x, various UNIX systems (SCO, QNX, Solaris, FreeBSD, AIX, HP-UX), macOS (10.1x to 14), embedded systems (WinCE 5.0/6.0, Windows XP Embedded), virtualization platforms (VMware ESXi, Fusion, Parallels Desktop), and Android from API 3.1.x. Compatibility with multiple operating systems enables seamless integration into heterogeneous IT infrastructures.

Mounting and Installation

The device can be mounted in various environments: as a desktop device, on a wall, or on a DIN rail (optional). Physical dimensions are 75.2 x 80 x 22 mm (with mounting ears) or 52 x 80 x 22 mm (without ears), with a weight of 340 g. Mounting options offer flexibility for placement in enclosures, workstations, or industrial control systems.
