A.Smartio CP-168U board will check the line status (CTS) before transmitting data if the RTS/CTS flow control feature is set to Enable in the configuration or application program. Refer to the Connection Cable and Cable Wiring chapter for proper wiring options, and check the line status of the suspected port using the diagnostic LED indicators on the mini tester.

B.The board’s control application might not be correctly written according to the corresponding API of the operating system. To verify the problem, run an existing application known to be good, or use utilities provided by Moxa, such as Pcomm Terminal Emulator or HyperTerminal under Windows NT/2000/XP and Windows 95/98.

Windows NT

This section is specific for troubleshooting under Windows NT. For general problems and solutions, please 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 conflicts with another adapter. 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 Smartio CP-168U board (Bus No=x, Dev No=x, Port1=COMx), with device number xx, conflicts with others.

The COM numbers for different boards are in conflict. Change the COM number mappings for the MOXA boards.

4.Windows NT system panics (blue screen).

The possible reason is an IRQ or I/O address conflict with other ISA Bus adapters, such as LAN or SCSI boards, or with the system BIOS. Refer to the corresponding problem in the previous section, “General Troubleshooting,” for solutions.

Windows 95/98

This section is specific for troubleshooting under Windows 95/98. For general problems
