Troubleshooting

Common C168P 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 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 16-bit slot this time. Sometimes the slot for plugging the board is bad. In this case, try other slots until you find a good one.

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

Hardware Causes and Solutions:

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

b.The cable or the board is 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.
