Appendix A - Troubleshooting - SeaLevel PLC-16.PCI User Manual

Sealevel Software is supplied with the Sealevel Systems adapter and may be used in the troubleshooting procedures.
Using this software and following these simple steps 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. While the Sealevel Systems adapter does
allow the sharing of IRQs, many other adapters (i.e. SCSI adapters & on-board serial ports) do not. The
IRQ is typically selected by the BIOS or Operating system. Some BIOS setup software will allow changing
the IRQ, but others do not. Another method of changing assigned resources is to try changing PCI slots.
This will typically cause the BIOS or OS to reassign the resources.
4. Make sure the Sealevel Systems adapter is securely installed in a motherboard slot.
