4-3. BE-3D SELF DIAGNOSTIC SOFTWARE
The identification of errors within the BE-3D chassis is triggered in one of two ways :- 1: Busy 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 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] See Table 1., non fatal errors are reported using this method.
