Moxa Nport 5230, 1 port RS422/485, 1 port RS232 content_copy

The Moxa NPort 5230 is a Device-Server from the NPort 5200 Series, specifically designed for integrating serial industrial devices such as PLCs, meters, or sensors into an Ethernet network. It connects two serial interfaces – an RS-232 port and an RS-422/485 port – with an Ethernet port, enabling communication between legacy systems and modern network infrastructures. The serial interfaces are connected via a terminal block, allowing flexible and robust cabling in industrial environments. Integration into existing networks is achieved using standard protocols such as TCP Server, TCP Client, UDP, and SNMP MIB-II, supporting remote management and configuration.

Applications

The NPort 5230 is suitable for space-critical applications in industry, particularly where serial devices need to be accessed via an Ethernet network. Typical use cases include remote machine monitoring, integration of measuring devices into building management systems, or communication with industrial controls. Support for Real COM/TTY drivers allows existing software to be used without modifications, simplifying migration to Ethernet-based systems.

Functions and Features in Detail

The device type offers automatic data direction control (ADDC) for the RS-485 interface, ensuring reliable communication in multi-point networks. Serial properties include baud rates from 110 to 230,400 bps, data bits 5 to 8, stop bits 1, 1.5, or 2, and parity types such as None, Even, Odd, Space, and Mark. Flow control is supported via RTS/CTS, DTR/DSR, or XON/XOFF. The RS-485 interface features an integrated 1 kΩ Pull High/Low resistor, improving signal stability.

Technology Explained Simply

The NPort 5230 features an Ethernet port (10/100BaseT(X)) with 1.5 kV isolation, ensuring a secure and noise-resistant network connection. Power supply is provided via a removable 3-pole terminal block in the voltage range of 12 to 48 VDC. At 12 VDC operating voltage, the current consumption is 325 mA. The device is housed in a metal housing, protecting against mechanical stress and electromagnetic interference. Dimensions are 90 x 100.4 x 22–35 mm (with mounting ears) or 67 x 100.4 x 22–35 mm (without ears), with a weight between 340 and 380 g.

Compatibility and Accessories

The NPort 5230 is designed for industrial environments and complies with standards EN 55032/35, FCC Part 15B, IEC 61000-4-2 to -4-11, and UL 60950-1. It is also certified for marine applications according to DNV. Operating temperature ranges from 0 to 55 °C (standard version), with a Wide-Temp version available from -40 to 75 °C. Humidity can reach 5–95 % RH without condensation. The MTBF (Telcordia) is 377,937 hours.

Mounting and Installation

Mounting is possible on a desk, wall, or optionally on a DIN rail. Installation is straightforward, as serial interfaces are connected via terminal block connectors and the network connection is made via a standard RJ45 port. Configuration can be performed via web (HTTP), Telnet, serial console, or a Windows utility software.

Operational Advantages

The NPort 5230 provides a reliable and low-maintenance solution for serial network integration. Support for standard protocols and broad driver compatibility (Windows, Linux, macOS, UNIX, Android, virtualization) simplifies integration into existing IT infrastructures. High MTBF and robust construction ensure long service life even in demanding environments.

Scope of Delivery

The scope of delivery includes the device itself, a quick start guide, and a warranty card.
