Modular I/O Configuration Guide58
• Declare IE (and/or FireFox) as an exception for the Windows Firewall to maintain proper UDP data transfer from and to the
JAVA applet.
• If you notice security issues, you may use the UDP PORT RANGE configuration (see “Setting the UDP Port Range” on page 59)
to limit the UDP port numbers instead of making an exception for all incoming network connections.
• Disable the browser’s caching features. The FC972’s web pages are designed to operate in LANs. The strategy developed for
surfing the internet (caching web site elements to save bandwidth download time), may confuse a more technical applica-
tion like the FC972 because it dynamically generates elements that must be gathered live from the web server.
IE: Set Check for newer versions of stored pages to Every time I visit a webpage
Firefox: Set Offline Storage to 0 MB of space for the cache.
