General Troubleshooting

1. While installing the driver, the MOXA driver is unable to detect the MOXA

PCI board.

Hardware causes and solutions:

A. The board is not installed. Please install it.

B. The board is not properly plugged into the system. If this is the case, re-

plug the board into a 32-bit PCI slot. It may also be the case that the slot

you’ve chosen could be damaged. In this case, try other slots until you

find one that works.

C. The motherboard does not have an available IRQ for the C168H/PCI board.

In this case, enter the BIOS and make sure an IRQ is available in the

PCI/PnP settings.

2. The MOXA board and driver are activated but cannot transfer data (either

transmitting or receiving).

Hardware Causes and Solutions:

A. Check to see if the cable is wired correctly. Refer to the Connection Option

(Opt8x) and Cable Wiring chapter for correct cabling information.
