General Troubleshooting
Common Intellio C320Turbo/PCIEL problems and possible solutions are listed below, in addition to those
operating systems specific ones. If you still have problems, contact your dealer or Moxa for help. Or report it
using “Problem Report Form” at the end of this manual to your dealer at once for technical support.
1.
MOXA PCI Express board can not 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, then re- install the board and make
sure that it fits well in a PCI Express slot this time. Sometimes the slot for plugging board is bad. In this
case, please try other slots until a good one is found.
2.
MOXA board and driver activated but can not transfer (transmitting/receiving) data.
Hardware Causes and Solutions:
a.
Check if wrong cable wiring. Refer to the “Connection Option and Cable Wiring” chapter for precise
pinouts of the connector type you are using.
b.
Cable, external modules or board is defective. You may use other port, cable or box or board to verify.
In addition, PComm utility “Diagnostic” for Windows is good for testing MOXA board and port condition.
If the report of diagnostic shows error, replace the error component.
Software Causes and Solutions:
a.
Intellio C320Turbo Series will check line status (CTS) before it sends data out if RTS/CTS flow control
feature is set to “Enable” in configuration or application program. Please see the “Connection Options
and Cable Wiring” chapter for proper wiring. Check the line status of the suspected port using the
diagnostic LED indicators on the mini tester.
b.
Perhaps the application controlling the board is not correctly written according to the corresponding API
of the operating system. To verify, please run existing and known good application or Moxa provided
utility. For example, under Windows PComm utility “Terminal emulator” or “Hyperterminal” is good for
testing COM ports. Under UNIX, “Terminal emulator” in the MOXA administration utility “mxadm” and
“stty”, “cat”, or “getty” are existed programs for testing tty port.
3.
“CPU/Basic Module not found” message appears. Or CPU/Basic Module can not download
firmware from the Control Board.
Hardware Causes and Solutions:
a.
Switch off the CPU/Basic Module. Check that the connection cable between the CPU/Basic Module and
the Control Board is correct and firmly connected on both sides. Switch on the CPU/Basic Module, then
power on the Control Board system to wait until the LED display of CPU/Basic Module reads “Ld”.
b.
Sometimes it happens when the total consumption of power in the system is higher than the power
adapter can provide. Especially when many interface boards including MOXA board(s) are plugged in the
system. It is recommended to replace the current power adapter with higher watt one. Or choose the
external power option if Intellio C320Turbo/PCIEL is used.
c.
If all the possible methods fail, the CPU/Basic Modules might be defective. Please check the module(s)
one at a time in the system to find out the defective one.
