Troubleshooting
The adapter should provide years of trouble-free service. However, in the event that it appears to be
functioning incorrectly, the following tips can eliminate most common problems without the need to call
Technical Support.
1.
Ensure that the Sealevel Systems SeaCOM 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.
The SeaCOM driver must be installed before the adapter is connected to your computer.
2.
Make sure the power supply is properly connected and the power LED on the front of the device is
lit.
3.
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 98, ME, 2000, XP, or Vista operating systems.
4.
While Device Manager is open, locate the COM ports (described under “Verifying Installation” in the
Installation and Configuration section of this manual).
5.
Once you have confirmed that the COM ports are listed in Device Manager, you can use the Sealevel
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 Tech
nical 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 SeaCOM folder under the ‘Start’
menu.
