Troubleshooting

Common Smartio C168H/PCI errors and possible corresponding solutions are listed below. If the problem still cannot be solved by following solutions given, contact dealers 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 PCI board cannot be detected by the MOXA driver while installing the driver.

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- plug the board in a 32-bit PCI slot this time. Sometimes the slot for plugging the board is malfunctioned. In this case, try other slots until you find a good one.

C.The motherboard does not have an available IRQ for the C168H/PCI board. 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 if cable wiring is connected correctly. Please refer to the

Connection Option (Opt8x) and Cable Wiring” chapter for correct cable connection.
