Troubleshooting

Common Industio CP-114 Series problems and possible solutions are listed below. If you still have problems, contact your dealer or Moxa for help. Or use the “Problem Report Form” at the end of this manual to report problems to your dealer at once for faster technical support.

General Troubleshooting

1. The MOXA driver, while installing the driver, cannot detect the MOXA PCI board.

Hardware causes and solutions:

a.The board is not installed or missing (absent). Please install it.

b.The board is not properly plugged in the system. If that is the case, re-install the board and make sure that it fits well in a 32-bit PCI slot this time. Sometimes the slot for plugging the board is bad. In this case, try other slots until you find a good one.

c.Your motherboard does not have a vacant IRQ for the CP-114 Series. Please enter BIOS and make sure there are available IRQ in PCI/PnP settings.

2.The MOXA board and driver are activated but cannot transfer (transmitting/receiving) data.

Hardware Causes and Solutions:

a.Check for wrong cable wiring. Refer to the “Connection Cable and Cable Wiring” chapter for precise pinouts of the connector type you are using.

b.The cables or the boards are defective. You may use other ports, cables or boards to verify. In addition, the PComm “Diagnostic” utility for Windows NT and Windows 95/98 is good for testing MOXA boards and port conditions. If Diagnostic reports error, replace the faulty components.

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.
