What is the WebNet?

The WebNet is a small electronic device, capable of serving as a gateway between another
electronic device and an ethernet network – for instance an intranet or the Internet. The
WebNet can connect to other electronic devices via e.g. its RS-232 interface.
The user interface of the WebNet consists of a number of web pages contained in the device
and presented by its built-in web server. A standard web browser is used to view and browse
these pages.
Once connected to the user's RS-232 device, further user interface web pages can easily be
developed by means of the built-in WebScript programming language. Thus, within short
time, the user's device can be configured and monitored with a standard web browser as
the only necessary application.

The WebNet Start kit

The WebNet itself is a "sub-credit-card" sized DIMM module, which makes it suitable as an
add-on module for another device. For the benefit of this module, two different start kits, a
"WebRJS-DCE" and a "WebRJS-PIC" adapter board is supplied. The start kits makes it
possible to connect power, ethernet and RS-232 via standard sockets. The WebRJS-DCE
and the "WebRJS-PIC" boards can thus be considered "motherboards" for the WebNet,
with the specialized purpose of providing RS-232 connectivity. Figure 1 shows the WebRJS
module with the WebNet module inserted. The "WebRJS-PIC" adapter board contains an
additional microcontroller, PIC16F876. The microcontroller opens possible connections to
a wide range of different hardware interface types. All I/O ports of the microcontroller is
accessable through a connector on the PCB.
