9 xPC Target Web Browser Interface
9-2
Web Browser Interface
xPC Target has a Web server built into the kernel that allows you to interact
with your target application using a Web browser. If the target PC is connected
to a network, you can use a Web browser to interact with the target application
from any host PC connected to the network.
Currently Microsoft Internet Explorer (Version 4.0 or later) and Netscape
Navigator (Version 4.5 or later) are the only supported browsers.

Connecting the Web Interface Through TCP/IP
If your host PC and target PC are connected with a network cable, you can
connect the target application on the target PC to a Web browser on the host
PC.
The TCP/IP stack on the xPC Target kernel supports only one simultaneous
connection, because its main objective is real-time applications. This
connection is shared between MATLAB and the Web browser. This also means
that only one browser or MATLAB is able to connect at one time.
Before you connect your Web browser on the host PC, you must load a target
application onto the target PC. The target application does not have to be
running, but it must be loaded. Also, your browser must have JavaScript and
StyleSheets turned on.
