Complete Ethernet connection solution to network-enable your serial devices
Compact size for easy integration
 
 
Introduction
 

NE-4120A offers a complete Ethernet connection solution (TCP Server, TCP Client, UDP) to network-enable your serial devices—only 57 x 40 mm, or less than half the size of your credit card—you can easily integrate NE-4110S into your serial device to make the device 10/100M Ethernet-ready.

Industrial-proven, built-in TCP/IP stack
NE-4120A's industrial-proven, built-in TCP/IP stack makes it easy for your R&D engineers to network-enable your serial device since they won't need to put a lot of effort into TCP/IP programming. The 10/100M Ethernet auto-sensing interface lets you enjoy the higher 100M speed when available. In addition, NE-4120A's 4 GPIO pins provide ample design flexibility, giving you the freedom to develop the features your customers need. The NE-4120A 5V design is better suited for today's equipment, and R&D engineers can spend less effort implementing the power circuit.

User-friendly configuration options
Configuration is done with a user-friendly Windows utility, Web browser, telnet console, or serial console. In addition, a Windows-based NECI (Network Enabler Configuration Interface) Library is available to help you develop your own Windows utilities.

Shorter time to market
The ready to go design of NE-4120A allows you to get your legacy serial device Ethernet-ready easily without modifying the circuit, and get your product to market in no time.

NE-4120-ST Starter Kit
An NE-4120-ST Starter Kit that includes everything you need to develop your application is also available. The Starter Kit includes an evaluation board, SDK, documentation, cables, and accessories.
