6-2 Intellio C218Turbo /PCI User's Manual
report of diagnostics shows error, replace the error component.
Software Causes and Solutions:
a. Intellio C218Turbo 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 Chapter “Connection Options (Opt8x) and Cable Wiring”
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 NT and Windows 95/98,
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.
Windows NT
This section is specific for troubleshooting under Windows NT. For general
problems and solutions, please see previous Section “General Troubleshooting”.
1. After system reboot, error message “MOXA C218 Turbo/PCI Multiport
Board #1 addr [XXX]: IRQ test failure!” appears in Event Log.
This indicates MOXA board is found but the IRQ is conflicting with other
adapter. Please make sure there is no conflict with other adapter's IRQ. Check
the PCI BIOS IRQ setting first. Make sure IRQ is available.
2. After system starts, error message “MOXA C218 Turbo/PCI Multiport
Board #1 addr [XXX] not found!” appears in the Event Log.
Shutdown the system first and refer to the problem 1 for solutions in the
previous section, “General Troubleshooting”.
