The Moxa NPort 5130 is a compact Device-Server for connecting serial RS-422/RS-485 devices to Ethernet networks. It serves as a bridge between legacy serial end devices and modern IP-based networks, enabling integration into existing IT infrastructures. Due to its compact design, it is particularly suitable for applications with limited space, such as industrial machines, card readers, or payment terminals.

Applications

The NPort 5130 is used in industrial environments where serial devices need to be accessed over Ethernet. It is suitable for systems communicating via RS-422 or RS-485, such as sensors, controls, printers, or measuring devices. Support for RS-422 and RS-485 enables reliable data transmission over long distances and in noise-sensitive environments. The integrated automatic direction control (ADDC) for RS-485 reduces configuration complexity and simplifies integration into existing bus systems.

Functions and Equipment in Detail

The Device-Server features a DB9 (male) serial interface and supports baud rates up to 921.6 kbps. Configuration is possible via several methods: through a web browser, Telnet, or the Windows Utility. Support for Real COM-/TTY drivers for Windows, Linux, and macOS enables transparent use of the serial interface in the network, as if it were locally connected. Configuration is flexible and allows various operating modes such as TCP Server, TCP Client, UDP, Pair Connection, and Ethernet Modem.

Technology Explained Simply

The network interface of the NPort 5130 consists of a 10/100BaseT(X) RJ45 port with magnetic isolation of 1.5 kV, providing high noise immunity and protection against voltage surges. Power supply is via a power supply socket with an input range of 12 to 48 VDC, with power consumption up to 200 mA at 12 VDC. The device is housed in a metal housing that protects against mechanical stress and electromagnetic interference. The operating temperature is in the standard range between 0 and 55 °C, with a version featuring an extended temperature range (Wide Temp) available up to -40 to 75 °C.

Compatibility and Accessories

The NPort 5130 is compatible with a wide range of operating systems, including Windows 95 to 11, Server 2000 to 2022, Linux Kernel 2.4.x to 6.x, macOS 10.1x to 14, various UNIX systems, and Android API ≥ 3.1. Network protocols include IPv4, SNMPv1, DHCP, BOOTP, DNS, HTTP, SMTP, ARP, ICMP, UDP, and TCP. Security features include authentication via a local database to prevent unauthorized access. Certifications include EMC standards such as EN 55032/35, FCC Part 15B, CISPR 32, immunity to interference according to IEC 61000-4-x up to 8 kV ESD, and safety standards EN/IEC 62368-1 and UL 60950-1.

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 holder) or 52 x 80 x 22 mm (without holder), and the weight is 340 g. Installation is performed by connecting to the network via RJ45 and to the power supply via the power supply socket. Configuration can be done directly on the device or via a network tool.

Advantages in Operation

The NPort 5130 offers high reliability with an MTBF of 2,836,863 hours. Integrated SNMP support enables network management with alarm functions, allowing status changes or error messages to be monitored. Flexible configuration and support for various operating modes increase adaptability to different application scenarios. The adjustable Pull High/Low and termination resistors for RS-485 allow optimal adaptation to the respective bus topology.

Scope of Delivery

The scope of delivery includes the NPort 5100 serial device, a power supply, a quick start guide, and a warranty card.

The warranty period is 5 years.
