Intellio C320Turbo User's Manual 6-3
c. IRQ settings of software and hardware do not match.
3. “CPU/Basic Module not found” message. Or CPU/Basic Module can not
download firmware from the Control Board.
Hardware Causes and Solutions:
a. Power off the CPU/Basic Module and Control Board system.
Check that the connection cable between the CPU/Basic Module and the Control
Board is correct and firmly plugged in on both sides.
Power on the CPU/Basic Module and wait until the LED display reads “Ld”. Power
on the Control Board system.
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 is used.
c. If all the possible methods fail, the CPU/Basic Modules might be defective. It is
recommended to check it under DOS with utility "SETUP" to verify the hardware
conditions.
4. Error messages appear on CPU/Basic Module LED display.
Any of the following messages means failure of the Intellio C320Turbo
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.
