Software Installation Troubleshooting
Problem Cause/Solution
When Matrix is launched, I see
a progress bar for a period of
time, but the browser window
showing the Matrix application
never appears.
There may be a pop-up blocker program running on your PC and preventing
the Matrix window from opening. Verify that you do not have a pop-up blocker
integrated with your IE browser. Programs such as the Google, Yahoo, and
AOL Toolbars—among many others, including IE itself if Service Pack 2 for
Windows XP is installed—contain such features. You must configure your
pop-up blocker to not block pop-ups from the Matrix Server software. If this is
happening at the server PC, the address the pop-up blocker must allow
pop-ups from is http://127.0.0.1
. If this is happening at a Matrix Client, the
pop-up blocker must allow pop-ups from http://<MatrixServer>, where
<MatrixServer> is the host name or IP address of the Matrix Server PC. How
the pop-up blocker is configured varies depending on the program, so check
that program’s documentation for instructions on how to do this. Usually, the
easiest solution is to disable the pop-up blocker entirely.
If a pop-up blocker causes the browser-based user interface to not show, the
underlying program that handles system communication, warning pop-ups,
sending e-mails, etc., should still function as normal.
When Matrix is launched, I get
an error that says a connection
could not be made to the Matrix
server.
Make sure you do not have a software firewall blocking ports 8080-8083 or
3306 at the Matrix Server and port 8082 at each Matrix Client. Matrix must be
able to use these ports for normal operation. By default, Service Pack 2 for
Windows XP turns the built-in Windows Firewall on; ensure that these ports
are open. The system may have a firewall from another vendor, such Syman-
tec’s Norton Internet Security, installed; this type of security software pack-
ages can contain firewalls and pop-up blockers, among other tools.
I’m sure I have no pop-up
blockers or firewalls on my
Matrix Client, but I still can’t
access the Matrix screens.
Verify with your IT network administrator that the network has no proxy servers
that block traffic on port 8080, the default port used by Matrix for http traffic.
The tank level information
screen has a white/gray rectan-
gle where the dispense infor-
mation should be.
The tank level information is displayed in a table in a Java applet. Verify that
you have the Java Plugin (version 1.4.2_04 or later) installed and that it is not
disabled in IE (Tools->Internet Options->Advanced tab, the section marked
Java (Sun)).
Also, in the Windows Control Panel, you should find a Java Plug-in icon. Dou-
ble-click the icon and verify that IE is set up to use the Sun JRE for viewing
applets.
After installing the JRE as
described in the installation
instructions, There is a coffee
cup icon in the system tray and
frequent pop-up windows.
What is this for, and is there a
way to turn off the pop-ups?
This is the Java Update mechanism that is part of the JRE, which, if enabled,
allows the JRE to make periodic automatic checks over the Internet for new
versions of the JRE. For the purpose of running Matrix this isn’t necessary. To
turn this off, go to Control Panel, double-click on the Java Plugin icon and
choose the Update tab. Clear the Check for Updates Automatically check-
box
