The Moxa NE-4110A-T is a compact embedded serial device server that integrates serial RS-422/RS-485 devices into existing networks via an Ethernet interface. With dimensions of 57 × 40 mm and a weight of 40 g, the module is particularly suitable for OEM applications where compact and powerful network integration into industrial or embedded systems is required. The device features an RJ45 Ethernet interface and supports communication at 10/100 Mbps, while the serial interface supports RS-422 and RS-485 standards. The baud rate can be set between 110 bps and 230,400 bps, allowing flexible adaptation to various serial devices.

Applications

The NE-4110A-T is used in industrial environments where serial devices such as sensors, controls, or measuring instruments need to be accessed over Ethernet. Support for protocols such as TCP Server, TCP Client, UDP, and Real COM enables flexible integration into various network environments. The ability to send real-time notifications via SNMP-Trap or email in case of events supports system monitoring and maintenance. The compact size makes it ideal for installation in devices with limited space, such as machine controls or automation technology.

Functions and Features in Detail

The device features two serial ports: one for the RS-422/RS-485 interface and one TTL console port. Serial settings include data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), parity (None, Even, Odd, Space, Mark), and flow control options such as RTS/CTS, DTR/DSR, and XON/XOFF. The Ethernet interface supports IEEE 802.3, 802.3u, and 802.3x standards and provides magnetic isolation of 1.5 kV, ensuring high immunity to interference. Network addressing is performed via DHCP, BootP, static IP address, or ARP.

Technology Explained Simply

The NE-4110A-T is based on a 16-bit MCU platform with 2 MB flash memory and 1 MB SDRAM. The four software-configurable DIO channels enable additional digital inputs/outputs that can be programmed according to application requirements. Power supply is via 5 VDC with a current consumption of 290 mA, corresponding to a power consumption of 1.5 W. The low power consumption makes the module suitable for energy-efficient systems. The operating temperature ranges from 0 to 55 °C in the standard range and from -40 to 75 °C in the extended range, enabling use in harsh environments. Humidity is 5 to 95 % (non-condensing).

Compatibility and Accessories

The module is designed for use with RS-422/RS-485 devices and can be used in systems requiring TCP/IP-based communication. Support for Real COM mode enables use as a virtual COM port under Windows systems. Network functions such as DHCP and static IP address ensure flexible integration into existing networks. Certifications according to EN 55032/24, FCC, CISPR 32, and IEC 61000 guarantee electromagnetic compatibility. Environmental compliance according to RoHS, CRoHS, and WEEE ensures proper disposal compliance.

Mounting and Installation

The module is connected to the network via the RJ45 interface and powered by an external 5 VDC source. The serial connection is made via the RS-422/RS-485 interface, with signals such as TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND configured according to application. Configuration is performed via the TTL console or network protocols. Mounting is typically done inside an enclosure or directly in the target system, with the compact design enabling flexible placement.

Operational Advantages

The NE-4110A-T offers a reliable and energy-efficient solution for integrating serial devices into networks. The high MTBF (Mean Time Between Failures) of 289,573 hours (according to Telcordia SR332) demonstrates the module’s high reliability. Support for SNMP and email notifications enables proactive system monitoring. The combination of compact design, low power consumption, and comprehensive protocol support makes the module a robust solution for industrial applications.

Certifications and Environmental Compliance

The device meets electromagnetic compatibility requirements according to EN 55032/24, FCC, CISPR 32, and IEC 61000. Environmental testing is performed according to IEC 60068. Environmental compliance is certified according to RoHS, CRoHS, and WEEE, ensuring proper disposal compliance. The 5-year manufacturer’s warranty underscores the product’s quality and reliability.
