Appendix A 

 Troubleshooting 

The adapter should provide years of trouble-free service. However, in the event that device appears to not 
be functioning incorrectly, the following tips can eliminate most common problems without the need to call 
Technical Support. 

1.

 

Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, 
controller cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if 
any) should be identified. 

2.

 

Configure  your  Sealevel  Systems  adapter  so  that  there  is  no  conflict  with  currently  installed 
adapters. No two adapters can occupy the same I/O address.  

3.

 

Make sure the Sealevel Systems adapter is using a unique IRQ The IRQ is typically selected via an 
on-board header block. Refer to the section on Card Setup for help in choosing an I/O address and 
IRQ. 

4.

 

Make sure the Sealevel Systems adapter is securely installed in a motherboard slot. 

5.

 

If you are utilizing an operating system prior to Windows 7, please contact Sealevel

‘s Technical 

support  as  directed  below  to  receive  more  information  regarding  the  utility  software  which  will 
determine if your product is functioning properly.  

6.

 

Only users running Windows 7 or newer should utilize 

the diagnostic tool 

WinSSD

’ installed in the 

SeaCOM folder on the Start Menu during the setup process. First find the ports using the Device 

Manager, then use ‘WinSSD’ to verify that the ports are functional.

 

7.

 

Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This will 
help eliminate any software issues and identify any hardware conflicts. 

If these steps do not solve your problem, please call Sealevel Systems’ Technical Support, (864) 843

-4343. 

Our technical support is free and available from 8:00 A.M.- 5:00 P.M. Eastern Time Monday through Friday.
