3. Enter 1 to 4 to test a port or ports on a specific RocketPort EXPRESS, or select
S to run the stress test on all RocketPort EXPRESS cards installed in the
system.
Note: The stress test requires a loopback plug for each port on each card.
Use Ctrl/Alt Delete to kill the diagnostic process at any time.
Testing a Port or Ports
Enter A to test all ports on the RocketPort EXPRESS or enter the port number
of a port that you want to test and follow the instructions on the screen. If you
are testing all of the ports and have only one loopback plug, you must move it
from port to port during the test.
Stress Testing the RocketPort EXPRESS
The stress test uses a default configuration to simultaneously stream data to
all ports of the RocketPort EXPRESS cards in a system until you stop the test.
To stop the test and review the results of the stress test, enter S.
To end the diagnostic, you may need to select b to return to a screen that contains
a q to quit. Type reboot, select Enter, and remove the CD from the drive when
prompted.
If the diagnostics did not detect a hardware problem, you may have a device driver
problem. See
Before Calling Technical Support on Page 27 for more information.
If the diagnostics could not find the card:
• Check for proper cable connections between the card and interface. Verify your
cables using
Connecting Serial Devices on Page 11.
• Verify that the loopback plug is firmly connected.
• Turn off the power and reseat the RocketPort EXPRESS card into the slot.
• Try running the diagnostics again. If they fail again, you may have a bad port,
contact
Technical Support on Page 31.
Troubleshooting Windows Systems
If you are using a RocketPort EXPRESS driver on a Windows system and the
diagnostic verified that the card is functional, you can check the following:
1. Verify that the RocketPort EXPRESS has installed by checking the Device
Manager to verify that the RocketPort EXPRESS card displays.
2. Verify that you are addressing the port correctly.
In many applications, device names above COM9 require the prefix \\.\ in
order to be recognized. For example, to reference COM20, use \\.\COM20 as
the file or port name.RocketPort EXPRESS.
3. After driver installation, if a port does not open; go to Ports COM & LPT, right-
click on the yellow exclamation mark on the port, and click Update Driver. Use
the same procedure used when installing the ports that are detected with plug
and play systems.
4. Enable the Verbose Event Log feature on the Options tab of the RocketPort
EXPRESS driver and then reboot the server.
5. Install and use one of the tools in the Comtrol Utility package. The Comtrol
Utility is available on the Software and Documentation CD or you can
download the latest version. The file is a self-extracting zip file that
automatically starts the installation procedure. It is not necessary to reboot
the PC after installation.
