6-2 Industio CP-114 User's Manual
Software Causes and Solutions:
a. For RS-422 mode, Industio CP-114 Series checks the line status (CTS) before it sends data out if
the RTS/CTS flow control feature is set to “Enable” in the configuration or application program.
Please refer to the “Connection Cable and Cable Wiring” chapter for proper wiring.
b. Perhaps the application controlling the board is not correctly written according to the
corresponding API of the operating system. To verify, please run an existing and known good
application or the provided utilities by Moxa. For example, under Windows NT and Windows
95/98, Pcomm “Terminal emulator” or “HyperTerminal” utilities are good for testing the COM
ports.
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 that the MOXA board is found, but the IRQ is conflicting with another adapter.
Please make sure there is no conflict with other adapter’s IRQ. Check the PCI BIOS IRQ settings
first. Make sure that an IRQ is available.
2. After the system reboots, the error message “Cannot find any configured
MOXA Smartio / Industio PCI Series board!” appears in the Event Log.
Please make sure the PCI board is seated firmly in the expansion slot.
3. The COM number of the Industio CP-114, with device number xx, conflicts
with others.
The COM numbers of different boards happen to be the same. Try to change the COM number
mappings.
4. Windows NT system panic (blue screen).
The possible reason is an IRQ or I/O address conflict with other ISA Bus adapters, like LAN and
SCSI boards, or the system BIOS. Please refer to the corresponding problem in the previous
section, “General Troubleshooting”, for solutions.
