SELF DIAGNOSTIC
SOFTWARE
The identification of
errors within the EX2L 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).
