The Moxa NE-4110S-T is an industrial embedded module for integrating serial RS-232 devices into Ethernet networks. It serves as a device server, enabling serial communication over IP networks, and is specifically designed for use in industrial environments. The module features a compact form factor in pin header format and is intended for installation in existing systems. It supports a wide range of operating systems, including Windows, Linux, and UNIX derivatives, and enables the use of serial devices via network protocols such as TCP/IP, UDP, and Real COM.

Applications

The NE-4110S-T is suitable for applications where serial devices such as sensors, controls, or measuring instruments need to be integrated into existing networks. Typical use cases include industrial automation, building automation, remote monitoring, or connecting legacy devices within modern IT infrastructures. The robust construction with an operating temperature range of -40 to 75 °C makes it suitable for harsh environments, such as production halls, outdoor installations, or vehicles.

Functions and Features in Detail

The module features two serial ports: one RS-232 port with full signal support (TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND) and one TTL console port. The RS-232 interface supports baud rates from 110 bps to 230.4 kbps, data bits from 5 to 8, stop bits 1, 1.5, or 2, and parity types including None, Even, Odd, Space, and Mark. Flow control can be configured via RTS/CTS, DTR/DSR, XON/XOFF, or without flow control. Operating modes include Real COM, TCP Server/Client, and UDP, providing flexible communication options.

Technology Explained Simply

The integrated magnetic isolation of 1.5 kV protects the module from voltage surges and electrical interference, which is particularly important in industrial environments. The 16-bit MCU processor ensures sufficient computing power, while the 2 MB Flash memory and 1 MB SDRAM provide storage for configurations and running processes. The Ethernet interface supports 10/100BaseT(X) with Auto MDI/MDI-X and is available via an 8-pin RJ45 connector. Support for standards IEEE 802.3, 802.3u, 802.3x ensures compatibility with common networking devices.

Compatibility and Accessories

The module is compatible with various operating systems and provides drivers for Windows Real COM, Linux TTY, UNIX Fixed TTY, and Android API. Configuration is performed via Web Console, Telnet, Windows Utility, or serial console, enabling flexible maintenance and customization. Supported network protocols include DHCP, HTTP, IPv4, Telnet, SNMPv1/v2c, TCP/IP, UDP, ARP, ICMP, SMTP, facilitating integration into existing network environments.

Mounting and Installation

The module is designed as a pin header module and is directly inserted into a compatible socket module or circuit board. Power supply is via 5 VDC with a current consumption of 290 mA. Installation requires no additional components; configuration is performed via the specified interfaces. Physical dimensions are 57 x 40 mm, and the weight is 40 g.

Operational Advantages

The industrial-grade temperature tolerance from -40 to 75 °C and EMC certification in accordance with EN 55032/24, CISPR 32, and FCC Part 15B Class A make the module suitable for demanding environments. The MTBF of 290,276 hours (according to Telcordia SR332) demonstrates high reliability. The 5-year manufacturer's warranty underscores the product's quality. The 4 digitally configurable I/O channels extend functionality by enabling additional input or output signals.

Certifications and Environmental Conditions

The module meets EMC requirements according to EN 55032/24, CISPR 32, and FCC Part 15B Class A. EMS tests include ESD (4 kV contact, 8 kV air), RS (3 V/m), EFT (1 kV power, 0.5 kV signal), Surge (1 kV), CS (3 V/m), and Magnetic Field (IEC 61000-4-8). Environmental tests in accordance with IEC 60068-2-1/2/3/14 ensure robustness under various climatic conditions. The operating environment requires an air humidity of 5–95 % (non-condensing).
