Embedded Web Controller

DESCRIPTION

Xecom’s XEWC86 W eb Contr oller is designed for embedded
control applications which require remote monitoring, update,
or control. The W eb Controller combines an industry standard
micro-controller with a integral web page server in one
compact module. The XEWC86 incorporates a standard
10Base-T interface so the web and network functions can be
easily integrated into equipment without a separate, complex
hardware and software development project.

In a typical application, the XEWC86 will have a user
developed control or monitoring task and a web server task
running concurrently. The application task presents real time
process and/or control information to the web server. The web
server then responds to queries from a standard web browser
such as Microsoft Internet Explorer or Netscape Navigator by
creating dynamic web pages containing the variable process
and control information in a format defined by the system
designer.

A TCP/IP Protocol stack and network firmware are integrated
into the module, providing a ready-to-play interface to an
internal Ethernet network and, if desired, to the worldwide
Internet. The XEWC86 family is loaded with firmware like
real time task management, dynamic web page hosting and
user web page developing tools, to support user application
development. Thus the XEWC86 dramatically reduces the
time and effort to add a web or network interface into an
embedded application.

The XEWC86 is based on a standard 186 family processor.
System designers can use standard C or C++ development
tools to quickly develop their control applications. Special
monitor and debugging firmware are provided in the module
to further speed development and shorten time-to-market

XEWC86/A family’s miniature form factor reduces the board
space required in a system to less than four square inches. The
XEWC86 family is available in two versions. XEWC86A has
eight analog channel inputs and two analog output channels,
both in 12-bit resolution. The XEWC86 has only digital I/O
lines and is suitable for a simple, lower cost design.
