0" indicates a normal channel, and 1" indicates a channel in error. For
example, if channels 5 (CH5) and 3 (CH3) are in error, bits 4 and 2
become 1". Data is expressed as 0014" (Hex).
Check the internal status of E5EK DRT by status A" or status B."
The following table shows the meanings of status A" bits:
