The Moxa NE-4110A is an embedded device server that makes serial devices accessible over an Ethernet network. It is specifically designed for space-critical applications where compact, high-performance Ethernet connectivity is required. The device features a serial port supporting RS-422/RS-485 and a TTL console port. The Ethernet interface enables data transmission at 10/100 Mbps and is equipped with an RJ45 connector. The integrated galvanic isolation of 1.5 kV protects the device from voltage surges and enables safe connection in industrial environments. The compact size of 57 × 40 mm makes the NE-4110A a small module that can be integrated into existing systems.

Applications

The NE-4110A is suitable for applications where serial devices such as sensors, controls, or measuring instruments need to be accessed over a network. It is particularly suitable for industrial environments where robust and reliable communication is required. The support for RS-422/RS-485 enables connection to devices communicating over long distances without signal loss. The small size and low power consumption of 1.5 W at 5 VDC also make it suitable for embedded systems and devices with limited power supply.

Functions and Features in Detail

The device server supports various operating modes, including TCP Server, TCP Client, UDP, and Real COM, enabling flexible integration into existing networks. Configuration is performed via the serial interface or over the network. Supported baud rates range from 110 bps to 230.4 kbps, with configurable data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parities (None, Even, Odd, Space, Mark). Flow control can be set to RTS/CTS, DTR/DSR, XON/XOFF, or no flow control. Integrated support for DHCP, BootP, ARP, and static IP addresses enables flexible network configuration. SNMP traps and email notifications can be triggered on events to monitor operation.

Technology Explained Simply

The NE-4110A is based on a 16-bit MCU platform with 2 MB flash memory and 1 MB SDRAM. The integrated galvanic isolation protects the device from electrical disturbances and enables safe communication in industrial environments. The Ethernet interface supports Auto MDI/MDI-X, simplifying cabling as no special cabling is required. Power supply is via 5 VDC with a current consumption of 290 mA, corresponding to a power consumption of 1.5 W. The header module form factor allows for easy mounting on a PCB header.

Compatibility and Accessories

The NE-4110A is compatible with RS-422/RS-485 interfaces and can be used in systems employing these standards. The serial interface supports a wide range of configurations to communicate with different devices. The Ethernet interface is designed for 10/100BaseT(X) and can be integrated into existing networks. Support for TCP/IP protocols enables communication with standard network devices. The device is designed for industrial environments and complies with EMC standards EN 55032/24, FCC Part 15B, and CISPR 32.

Mounting and Installation

The NE-4110A is mounted as a header module on a corresponding PCB header. Wiring is done via the RJ45 network cable and the serial cable. Configuration can be performed via the serial interface or over the network. Power supply is via 5 VDC. Installation requires no special tools, as the device is simply plugged onto the header.

Operational Advantages

The NE-4110A offers a reliable and compact solution for integrating serial devices into Ethernet networks. The low power consumption and compact form factor make it ideal for embedded systems. The integrated galvanic isolation increases safety and reliability in industrial environments. Support for SNMP traps and email notifications enables efficient monitoring of the device. The 5-year manufacturer's warranty provides additional security for operation.
