The Moxa NE-4100T-T is an embedded Device-Server for integrating serial devices into Ethernet-based networks. It serves as a bridge between legacy serial peripheral devices and modern IP networks, enabling communication via TCP/IP protocols. The device is designed in an extremely compact form factor, with dimensions of 45 × 36 mm and a weight of 20 g, making it ideal for use in limited space environments, such as industrial controls or embedded systems. The form factor as a Drop-In-Module or Pin-Header allows for flexible mounting in existing devices or development boards.

Applications

The NE-4100T-T is designed for applications requiring the connection of serial interfaces such as TTL over Ethernet. Typical use cases include networking sensors, control devices, industrial machines, or communication modules operating via TTL interfaces. The compact design and low power consumption of 1.5 W at 5 VDC make the device particularly suitable for energy-efficient and space-saving systems. Support for operating systems such as Windows, Linux, UNIX, macOS, and Android extends its applicability across various environments.

Functions and Features in Detail

The device features an Ethernet interface with 10/100 Mbps (10/100BaseT(X)) and Auto MDI/MDI-X, enabling flexible cabling without requiring additional cable reconfiguration. The serial interface supports TTL (depending on model), with baud rates adjustable between 110 bps and 230.4 kbps. Configuration of data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parity (none, even, odd, Space, Mark) is performed via software. Flow control options include RTS/CTS, DTR/DSR, XON/XOFF, and no control. Additionally, 4 software-configurable digital I/O channels are integrated, which can be used for status monitoring or control tasks.

Technology Explained Simply

The NE-4100T-T is based on a 16-bit microcontroller platform with 2 MB Flash memory and 1 MB SDRAM. Power supply is via 5 VDC, with a current consumption of 290 mA. The Ethernet interface is equipped with magnetic isolation of 1.5 kV, providing high immunity against electrical surges. Operating modes include Real COM, TCP Server, TCP Client, and UDP, allowing the device to function as either a server or client in networks. Network configuration is performed via DHCP, BootP, static IP addresses, or ARP. SNMP and E-Mail alerts for events enable proactive monitoring of the device.

Compatibility and Accessories

The device is designed for use in systems with serial TTL interfaces. Compatibility with various operating systems (Windows, Linux, UNIX, macOS, Android) allows broad integration into different IT and industrial environments. The form factor as a Drop-In-Module or Pin-Header enables integration into existing hardware boards.

Mounting and Installation

Mounting is performed depending on the application, either via Pin-Header connectors or as a Drop-In-Module into corresponding sockets. Configuration is done via a software or web interface, where settings for IP address, operating mode, serial parameters, and digital I/Os are adjusted. Installation requires no special tools, as connections are made directly to the board.

Advantages in Operation

The NE-4100T-T is characterised by high reliability, evidenced by an MTBF of 288,173 hours (according to Telcordia SR332). The operating temperature ranges from 0 to 55 °C (standard), with a version available with an extended temperature class (Wide Temp: -40 to 75 °C). Humidity tolerance of 5 to 95 % (non-condensing) allows use in various environments. Certifications according to EN 55032/24, CISPR 32, FCC Part 15B Class A, and electromagnetic compatibility tests in accordance with IEC standards ensure safe and interference-free operation. The 5-year manufacturer's warranty underscores the product's quality.
