The Moxa NE-4100T is a compact embedded device server, specifically developed for integrating serial devices into networks. The module enables network capability for serial end devices communicating via TTL interfaces, and is optimized for use in embedded systems. With a drop-in form factor and compact dimensions of 45 × 36 mm, it is ideal for space-saving installation solutions. Power supply is via 5 VDC, with a total power consumption of 1.5 W, ensuring high energy efficiency.

Applications

The NE-4100T is used in industrial and embedded systems where serial devices such as sensors, controls, or measuring instruments need to be accessed over a network. It is particularly suitable for applications requiring a compact, energy-efficient, and reliable interface, such as in automation technology, building automation, or networked machine controls. Support for TTL interfaces makes it suitable for devices with digital interfaces that do not have RS-232/422/485 interfaces.

Functions and Features in Detail

The device features an Ethernet interface with 10/100 Mbps and Auto MDI/MDI-X, enabling flexible connection to networks. The serial interface supports TTL signals, with baud rates adjustable between 110 bps and 230.4 kbps. Additionally, the module offers four digital I/O channels that are software-configurable. Operating modes include Real COM, TCP Server, TCP Client, UDP, and Pair Connection, covering a wide range of communication requirements. Network configuration is performed via DHCP, BootP, static IP addresses, or ARP support.

Technology Explained Simply

The NE-4100T acts as a bridge between serial devices and an Ethernet network. It converts serial data into IP packets and forwards them over the network. The Real COM server function allows the serial device to be used over the network as if it were a local COM port. Support for SNMPv1/v2c and SMTP alerts enables monitoring of network events and automatic notification in case of faults. Power supply via 5 VDC and low power consumption of 1.5 W make the module especially suitable for battery-powered or energy-optimized systems.

Compatibility and Accessories

The module is compatible with a wide range of operating systems, including Windows, Linux, UNIX, and macOS, ensuring broad applicability in various environments. The serial interface is designed for TTL signals, making it suitable for devices with digital interfaces. The Ethernet interface supports standard protocols such as TCP/IP, UDP, and ARP, facilitating integration into existing networks.

Mounting and Installation

The NE-4100T is supplied in drop-in format, allowing direct mounting on a socket. Installation is performed by connecting to the device’s serial TTL interface and linking to the Ethernet network via the integrated RJ45 or pin header interface. Configuration is done via a web interface or network protocols. The operating temperature range is standard between 0 °C and 55 °C, with an extended temperature version (–40 °C to 75 °C) available. Storage conditions are –40 °C to 60 °C, and relative humidity is 5–95 % (non-condensing).

Operational Advantages

The NE-4100T offers high reliability with an MTBF of 288,173 hours (according to Telcordia SR332). Low power consumption and compact design reduce space requirements and operating costs. Support for various operating modes and network monitoring via SNMP and email alerts increases flexibility and maintainability. Certifications according to EN 55032/24, FCC Part 15B Class A, and CISPR 32 ensure good electromagnetic compatibility. Compliance with RoHS, CRoHS, and WEEE demonstrates the environmental compatibility of the product.
