6-2 Smartio CP-168U User’s Manual
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.
