A.1 Troubleshooting Tips
The adapter should provide years of trouble-free service. However, if it appears to
be functioning incorrectly, the following tips can eliminate most common
problems.
1. Make sure that the software has been installed on the machine so that the
necessary files are in place to complete the installation. To confirm installation,
click on the Windows “Start” button and then select “All Programs.” You
should see the “SeaCOM” program folder listed.
NOTE: The driver must be installed before the adapter is connected to your
computer.
2. Check to make sure that USB support is enabled and functioning properly in
the operating system. The presence of the “Universal Serial Bus controllers”
listing in Device Manager will confirm that USB support is enabled in Windows
98SE, ME, 2000, XP, or Vista operating systems.
3. While Device Manager is open, locate the COM ports (described under
“Verifying Installation” in the Installation and Configuration section
of this manual).
4. Once you have confirmed that the COM ports are listed in Device Manager,
you can use the WinSSD utility and a loopback plug to test communications.
Detailed help is included in the WinSSD utility.
• If you have a loopback plug, put it on the DB9 connector that you want to test.
If you don’t have a loopback plug, contact Technical Support for assistance.
• If you’re testing RS-485 mode, you’ll need to have ECHO enabled otherwise the
following test will fail. Refer to the Hardware Configuration section for
instructions on enabling ECHO.
• To test communications, launch the WinSSD utility in the folder under the
“Start” menu.
• On the “Port Information” tab, select the COM port you want to test and click
on the “Open” button (see Figure A-1).
