Edit the file DA-5.2/framebuilder.html. Near the middle of the file you will see two lines with HTML tags that begin with <PARAM NAME=.... One line has the name 'port' and one has the name 'host'. Edit the 'port' line's VALUE so that it is the port to which your web server listens. The default web server port is 80. Edit the 'host' line's VALUE so that it is the IP name of your web server machine.
