SELF DIAGNOSTIC SOFTWARE
The identification of errors within the EG1L-L
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).
