Troubleshooting

Common Smartio CP-104UL board errors and possible corresponding solutions are given below. If the problem still cannot be solved after following these suggestions, 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 to receive 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. 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-104UL 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.

Software Causes and Solutions:

A.Smartio CP-104UL board will check the line status (CTS) before transmitting data if the RTS/CTS flow control feature is set to Enable in the configuration or application program. Refer to the Connection Cable and Cable Wiring chapter for proper wiring options, and check the line status of the suspected port using the diagnostic LED indicators on the mini tester.

B.The board’s control application might not be correctly written according to the corresponding API of the operating system. To verify the problem, run an existing application known to be good, or use utilities provided by Moxa, such as Pcomm Terminal Emulator or HyperTerminal under Windows NT/2000/XP and Windows 95/98.
