NE-4100 Series User’s Manual Introduction
1-2
Overview
NE-4100 Series modules are a type of embedded device server or network enabler. An NE-4100
Series module may be installed in or attached to a serial device to make it accessible from a
network. There are three types of module offered: drop-in (NE-4100T), RJ45 (NE-4110S,
NE-4110A), and pin header (NE-4120S, NE-4120A). The last letter of the model number indicates
the serial signal supported by the module. T indicates a TTL connector, S indicates an RS-232
connector, and A indicates an RS-422/485 connector. Each module includes 4 digital input/output
channels, also known as DIO channels or GPIO channels.
NE-4100 Series modules are very compact—less than half the size of a credit card. At such a small
size, they can be installed into almost any serial device. Each NE-4100 Series module also comes
with a built-in TCP/IP stack for fast integration. Engineers can spend less time on TCP/IP
programming, and focus more on developing other major features, thereby shortening your
product’s time to market. Modules may be easily configured with a user-friendly Windows utility,
web browser, serial console, or Telnet console. In addition, a Windows-based NECI (Network
Enabler Configuration Interface) library is available to help you develop your own Windows
utilities.
Each module comes with a complete development kit containing an evaluation board, documents,
sample code, cables, and accessories.
