The Moxa NPort 5232-T is an industrial device server designed specifically for integrating serial devices into IP-based networks. It enables the connection of devices such as measuring instruments, sensors, or controls via RS-422/485 interfaces with Ethernet networks, allowing for centralized data transmission and remote control. The device features two serial ports connected via a terminal block and one Ethernet port with 10/100BaseT(X) for network communication. Its compact metal design makes it particularly suitable for industrial environments with limited space, and it can be mounted on a desk, on a wall, or on a DIN rail.

Applications

The NPort 5232-T is used in industrial automation systems, process monitoring, and applications where existing serial devices need to be integrated into modern networks. Support for RS-422/485 enables communication with a wide range of industrial sensors, controls, and machines, which often feature these interfaces. The maritime certification (DNV) also makes the device suitable for use in marine applications.

Functions and Equipment in Detail

The device supports various operating modes, including TCP Server, TCP Client, UDP, Real COM, Pair Connection, Reverse Telnet, and Ethernet Modem. The Real COM/TTY driver integration allows existing software solutions to be used without modifications, as the serial ports appear as COM ports in the network. Configuration is performed via a Windows utility, a web interface (HTTP), Telnet, or a serial console. The integrated automatic data direction control (ADDC) for RS-485 reduces connection complexity, as no additional control line is required. The serial interfaces support baud rates from 110 to 230400 bps, data bits 5 to 8, stop bits 1, 1.5, or 2, and parities None, Even, Odd, Space, and Mark. Flow control options include RTS/CTS, DTR/DSR (RS-232 only), and XON/XOFF.

Technology Explained Simply

The NPort 5232-T acts as a bridge between serial devices and IP networks. It converts serial data into IP packets and forwards them over the network. The Ethernet interface provides 1.5 kV isolation, protecting the device from overvoltage. The serial ports feature 1 kΩ pull-up/down resistors, improving signal stability in RS-485 applications. Power supply is via a 3-pole detachable terminal block with an input voltage of 12 to 48 VDC. At 12 VDC, the power consumption is 280 mA.

Compatibility and Accessories

The device is compatible with a wide range of operating systems, including Windows (95 to 11, Server 2000 to 2022, CE, XP Embedded), Linux (Kernel 2.4.x to 6.x), macOS (10.1x to 14), various UNIX systems (SCO, QNX, Solaris, FreeBSD, AIX, HP-UX), virtualization environments (VMware ESXi/Fusion, Parallels Desktop), and Android (API 3.1.x+). Network protocols include TCP/IP, UDP, DHCP, BOOTP, DNS, SNMPv1, ICMP, Telnet, HTTP, SMTP, SNTP, and ARP. Certifications include EMC (EN 55032/35, CISPR 32, FCC Part 15B), EMS (IEC 61000-4-2 to -4-11), Safety (UL 60950-1), Maritime Use (DNV), and environmental standards (RoHS, CRoHS, WEEE).

Mounting and Installation

The device can be mounted on a desk, on a wall, or on a DIN rail. Mounting is done using an optional mounting kit. Dimensions are 67 × 100.4 × 22 mm (without holder) and 90 × 100.4 × 22 mm (with holder). Weight is 360 g. Installation requires no special tools, as connections are made via terminal block and RJ45.

Operational Advantages

The NPort 5232-T offers reliable data transmission with high availability. The MTBF (Telcordia) is 309,383 hours, ensuring high operational reliability in industrial applications. The integrated overvoltage protection safeguards the device against transient voltage spikes. Support for various operating modes and network protocols enables flexible integration into existing networks. The web interface and Windows utility simplify configuration and maintenance.
