CHAPTER 5: Troubleshooting
A Serial Utility Diskette is supplied with the Adapter and will be used in the
troubleshooting procedures. By using this diskette 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 the 4-Port Card Serial Host Adapter with ISP so that there is no
conflict with currently installed adapters. No two adapters can occupy the same
I/O address.
3. Make sure the Adapter is using a unique IRQ. While the 4-Port Card Serial
Host Adapter with ISP does allow the sharing of IRQs, many other adapters,
such as SCSI adapters and on-board serial ports, do not. The IRQ is typically
selected via an on-board header block. Refer to Chapter 3 for help in choosing
an I/O address and IRQ.
4. Make sure the Adapter is securely installed in a motherboard slot.
5. Use the supplied diskette and this manual to verify that the Adapter is
configured correctly. The supplied diskette contains a diagnostic program
(“SSD”) that will verify if the Adapter is configured properly. Refer to the
“README” file on the diskette for detailed instructions on using “SSD.”
6. Refer to the diskette for any postproduction manual updates and application-
specific information.
7. Always use this diagnostic software when troubleshooting a problem. This will
eliminate the software issue from the equation.
