5.4.2. How to read the returned value and the self-diagnosis serial control command.
Use the command "QVX:ERRS1" to get the information of Self-diagnosis for this model.
The returned value provides the 128 bit self-diagnosis information as follows.
(Table below shows no error occurs)

The returned value "N" indicates normal and "E" indicates error status. The first bit 0 starts from right and it ends by bit 127
at left.
Example: If the self-diagnosis information is inquired under the condition of the power fan error, the "E" will appear on 47th
bit as the below.
"E" will appear on lower 47th bit.
