The 0s represent masked faults, 1s represent unmasked faults. The 0s and 1s also
represent a set of two binary numbers. In the example above, binary 1101 = hex D, and
binary 1011 = hex B.
Use the following chart to convert binary values that match the desired masked/unmasked
faults settings into hex values.
Binary Hex Binary Hex

Then, select the appropriate hex values from the drop-down selection list for each digital
masking parameter on the MiniMAC screen.
