The Moxa NPort 5110A is an industrial Device-Server with an RS-232 interface, enabling serial devices to be accessible over an Ethernet network. It is designed for use in demanding industrial environments and offers high reliability as well as various operating modes. Integration into existing networks is facilitated by support for baud rates up to 921.6 kbps and a wide range of operating system drivers. HTTPS encryption and advanced authentication protocols ensure enhanced protection for data transmission. The robust metal housing, wide voltage range, and support for various mounting options make the NPort 5110A a flexible device for industrial applications in a temperature range of 0 to 60 °C.

Applications

The NPort 5110A is suitable for network integration of serial devices such as measuring instruments, controls, printers, or industrial sensors. It is used in production facilities, power supply networks, building technology, and other areas where serial communication over Ethernet infrastructures is required. Support for various operating modes allows flexible adaptation to different requirements, such as use as a TCP client or server, UDP connection, or Reverse Telnet.

Functions and Equipment in Detail

The device server features an RS-232 interface with a DB9 male connector and supports various communication parameters such as data bits (5–8), stop bits (1, 1.5, 2), parity (none, even, odd, Space, Mark), and flow control methods (RTS/CTS, DTR/DSR, XON/XOFF). Baud rates can be set from 50 bps to 921.6 kbps. The serial interface is equipped with a 15 kV ESD protection and a 0.5 kV serial surge protection, enhancing robustness in industrial environments. The Ethernet interface operates in the 10/100BaseT(X) standard and is fitted with 1.5 kV magnetic isolation to prevent interference and surges.

Technology Explained Simply

The NPort 5110A acts as a bridge between serial devices and Ethernet networks. It enables the transmission of serial data over the network, making devices accessible via TCP/IP protocols. Configuration is performed via a serial console, and the device supports various network protocols including DHCP, ARP, BOOTP, DNS, HTTP, HTTPS, ICMP, IPv4, LLDP, SMTP, SNMPv1/v2c, TCP/IP, Telnet, and UDP. HTTPS encryption (TLS 1.2) protects data transmission from unauthorized access. Authentication is performed via a local database, supporting encryption algorithms such as AES-128, SHA-1, RSA-1024, and SHA-256.

Compatibility and Accessories

The NPort 5110A is compatible with operating system drivers for Windows, Linux, UNIX, macOS, and Android. It also supports virtual machines such as VMware, Parallels, and Fusion. Network management functions include IGMP filtering (v1/v2) and SNMPv1/v2c, facilitating integration into existing network management systems. The serial interface is designed for connection to devices using RS-232 signals (TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND).

Mounting and Installation

The device can be mounted on a DIN rail, on a wall, or on a desk. The metal housing is compact (dimensions with mounting: 75.2 x 80 x 22 mm) and provides mechanical protection. Power supply is via an input range of 12 to 48 VDC, with power consumption at 12 VDC being 82.5 mA. Power supply is via a power socket.

Operational Advantages

The NPort 5110A offers high operational reliability through an integrated watchdog timer, which enables recovery in case of system failures. The MTBF (Mean Time Between Failures) is 2,231,530 hours according to Telcordia Standard TR/SR, indicating high reliability. Certifications include EMC (EN 55032/35), EMI (CISPR 32, FCC Part 15B Class A), EMS (IEC 61000-4-2 to -4-11), and safety standards (UL 60950-1). The device is RoHS, CRoHS, and WEEE compliant. Operating temperature ranges from 0 to 60 °C, storage temperature from -40 to 75 °C, with humidity levels between 5 and 95 % (non-condensing).
