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.

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