6-2 Smartio C168H/PCI User’s Manual
B. Either the cable or board could be defective. Try other ports, cables, and
boards to verify this, or use PComm Diagnostic utility to test the MOXA
board and port conditions. If Diagnostic reports an error, replace the faulty
components.
Software Causes and Solutions:
C. The Smartio C168H/PCI board will check the line status (CTS) before
transmitting data if the RTS/CTS flow control feature is set to Enable in
either the configuration or application program. Refer to the Connection
Option (Opt8x) and Cable Wiring chapter for proper wiring specs, and
check the line status of the suspected port using the diagnostic LED
indicators on the mini tester.
D. The board controlling application might not be written correctly for the
corresponding API of the operating system. To see if this is the case, run
another application that you know is good, or use utilities provided by
Moxa. You can either use PComm Terminal emulator or HyperTerminal
under Windows NT and Windows 95/98.
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 that the MOXA board was found, but the IRQ that was assigned
conflicts with another adapter’s IRQ setting. Check the PCI BIOS IRQ settings
first, and then select an available IRQ.
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 C168H/PCI (Bus No=x Dev No=x,
Port1=COMx), with device number xx, conflicts with others.
