The Moxa NPort 5230-T is an industrial device server that integrates serial devices such as PLCs, meters or sensors into IP-based networks. It connects two serial interfaces with an Ethernet port and enables bidirectional data access over TCP/IP, without requiring existing software to be modified. Integration is achieved via Real COM- and TTY drivers, which are available for a wide range of operating systems, including Windows, Linux, macOS, various UNIX systems, as well as Android and virtual environments such as VMware ESXi. The devices are designed for use in industrial environments where reliability and compact design are required.

Applications

The NPort 5230-T is suitable for applications where serial devices need to be accessed over a network, for example in automation technology, energy supply or process monitoring. Support for RS-232, RS-422 and RS-485 enables connection to various device types. The model designation -T indicates an extended operating temperature range from -40 to 75 °C, enabling use in extreme environments such as outdoor installations or climate-stressed industrial facilities. The devices are also certified for marine applications (DNV), making them suitable for use on ships or coastal installations.

Functions and Equipment in Detail

The device server features two serial ports: one RS-232 port and one combined RS-422/RS-485 port, which is connected via a terminal block. The serial interfaces support baud rates from 110 to 230400 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 achieved via RTS/CTS, DTR/DSR or XON/XOFF. For RS-485, automatic direction control (ADDC) is integrated, enabling communication without additional control. The pull-high/low resistors are 1 kΩ, except for model 5210.

Technology Explained Simply

The Ethernet interface supports 10/100BaseT(X) and is equipped with 1.5 kV galvanic isolation, protecting against interference and voltage spikes in the network. Power supply is via a 3-pole terminal block with an input voltage of 12 to 48 VDC. Power consumption is 325 mA at 12 VDC. The device is housed in a metal housing, which is mechanically robust and designed for industrial environments. Dimensions range from 67–90 mm (width) × 100.4 mm (height) × 22–35 mm (depth), and weight is 340–380 g. Mounting can be done on a desktop, on a wall, or optionally on a DIN rail.

Compatibility and Accessories

The NPort 5230-T supports various operating modes such as TCP Server, TCP Client, UDP, Real COM, Pair Connection and Reverse Telnet. Configuration is possible via a web console, Telnet, a serial console or a Windows utility. For network management, protocols such as SNMPv1, SNTP, SMTP, DHCP, DNS, ARP and BOOTP are available. The devices comply with various certifications, including UL 60950-1 for safety, EN 55032/35 as well as FCC Part 15B for EMI/EMS, RoHS, CRoHS and WEEE for environmental requirements. The MTBF (Telcordia) is 377,937 hours.

Mounting and Installation

Installation involves connecting the serial devices to the terminal block interfaces and connecting the Ethernet port via a network cable. Power supply is connected via the 3-pole terminal block. Mounting is flexible: the device can be placed on a desktop, mounted on a wall, or optionally installed on a DIN rail. Configuration is done via the web console or other mentioned methods, with a quick start guide included in the delivery scope.

Operational Advantages

The NPort 5230-T offers a reliable and flexible solution for integrating serial devices into IP networks. Support for many operating systems and drivers enables easy integration into existing systems. Galvanic isolation in the Ethernet port protects against interference, and the extended temperature range allows use in harsh environments. DIN rail mounting enables compact installation in enclosures. Certifications for marine applications and environmental standards increase operational safety in specific industries.

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