Chapter 6 Troubleshooting
Common Smartio C104 PCI Series 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.
6.1 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-install the
board and make sure that it fits well in a 32-bit PCI slot this time. Sometimes the
slot for plugging the board is bad. In this case, try other slots until you find a good
one.
c. Your motherboard does not have a vacant IRQ for the C104 PCI Series. 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 for wrong cable wiring. Refer to the “Connection Cable and Cable Wiring”
chapter for precise pinouts of the connector type you are using.
b. The cable or the board are 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.
