WAX2F SELF DIAGNOSTIC
The identification of errors within the WAX2F chassis is triggered in one of two ways :-
1: Busy or
2: Device failure to respond to IIC.
In the event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous flashing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device number will be displayed through the LED (Series of flashes which must be counted).
