AE-6D SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-6D 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) See table 1., non fatal errors are reported using this
method.

Device acknowledge is used to check IIC errors. Device acknowledge is checked by sending an IIC start sequence during CRT power on. Each
device is checked three times, if there is no acknowledge after each attempt, it will be regarded as an error.
There are three steps to check for errors.
device is checked three times, if there is no acknowledge after each attempt, it will be regarded as an error.
There are three steps to check for errors.
1.
IIC line 0
If all devices except the NVM have errors, IIC line 0 error is displayed.
If all devices except the NVM have errors, IIC line 0 error is displayed.
2.
Board check
If all devices mounted on one board have errors, board error is displayed.
If all devices mounted on one board have errors, board error is displayed.
3.
Each device check
If IIC line error and board error are not detected then the device with the error is displayed.
If IIC line error and board error are not detected then the device with the error is displayed.
The detected errors can be displayed as follows :
