Serial Utility test software is supplied with the Sealevel Systems adapter and will be used in the
troubleshooting procedures. By using this software and following these simple steps, most common
problems can be eliminated 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.

on-board header block. Refer to the section on Card Setup for help in choosing an I/O address and
IRQ.
