Technical Reference

Windows NT

This section is specifically for troubleshooting under Windows NT. For general problems and solutions, see the previous section, “General Troubleshooting.”

1.After the system reboots, the error message “Another driver in the system, which did not report its resources, has already claimed the interrupt used by xxx.” appears in the Event Log.

This indicates the MOXA board was found, but the IRQ is conflicting with another adapter. Please check the PCI BIOS IRQ settings first and then select an IRQ that is available.

2.After the system reboots, the error message “Cannot find any configured MOXA Smartio/Industio Series board!” appears in the Event Log.

Make sure the PCI board is seated firmly in the expansion slot.

3.The COM number of the CP-132U Series conflicts with others.

The COM numbers of different boards happen to be the same. Try changing the COM number mappings.

4.Windows NT system panic (blue screen).

The possible reason is an IRQ or memory conflict with other ISA Bus adapters, like LAN and SCSI boards, or the system BIOS. Refer to the corresponding problem in the previous section, “General Troubleshooting,” for possible solutions.
