C320Turbo/PCIEL
Troubleshooting
6-2
4.
Error messages appear on CPU/Basic Module LED display.
Any of the following messages means failure of the Intellio C320Turbo/PCIEL initialization.
E0: CPU/Basic Module ROM error.
E1: CPU/Basic Module RAM error.
E2: No UART Module present.
E4: The power to the CPU/Basic Module has been switched off and on swiftly, or some Module is missing
during the power-off time.
E5: The connection between Modules is loose or broken.
A1: CPU/Basic Module execution failure.
A2: CPU/Basic Module can not communicate with Control Board.
10: The first UART Module initialization failure.
20: The second UART Module initialization failure.
30: The third UART Module initialization failure.
40: The forth UART Module initialization failure.
Hardware Causes and Solutions:
If the error message persists after check, return the unit for repair.
As “E0”, “E1” or “A1” occurs, usually you have to turn off and on the CPU Module. If problem persists, the
CPU Module might be defective.
As “E2” occurs, turn off the CPU Module, firmly connect the UART Modules, and turn the power back on.
As “E4” occurs, usually you have to turn off the CPU/Basic Module, then turn on at least time interval 3
seconds. Or check if the total number of ports (or modules) is correct or not.
As “E5” occurs, it may indicates that the cables between modules should be fastened carefully.
As “A2” occurs, check the link between CPU Module and Control Board is fastened carefully.
As “10”, “20”, “30” or “40” occurs, make sure the connection between modules is proper.
5.
Upon system startup or driver initialization, the “Number of ports mismatch” message appears.
Hardware Causes and Solutions:
The total number of ports installed is less than that of configured.
a.
Shut off the system and check all modules and their connections. Make sure that all the module(s) is(are)
fastened properly.
b.
Run the board configuration program to check the board configuration. For Intellio C320Turbo/PCIEL,
connect the CPU/Basic Module with proper number of UART/Extensive Module(s) as configured in
configuration program.
c.
If all the possible methods fail, one of the module(s) might be defective. Please check the module(s)
one at a time in the system to find out the defective one.
