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. Please install the board in an empty PCI slot.

B.The board is not properly plugged into the system’s PCI slot. If that is the case, re- plug the board in a 32-bit PCI slot. It may also be the case that the PCI slot is defective. In this case, try other PCI slots until you find one that works.

C.The motherboard does not have an available IRQ for the CP-168U board. Enter the PC’s BIOS and make sure an IRQ setting is available in the PCI/PnP settings.

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

Hardware Causes and Solutions:

A.Make sure the cable wiring is connected correctly. Refer to the “Connection Cable and Cable Wiring” chapter to see correct cable connection options.

B.The cable or the board are probably defective. Please try other ports, cables, or boards to verify this, or use the PComm Diagnostic utility to test MOXA board and port conditions. If Diagnostic reports an error, replace the faulty components.
