Description
Vct_enable
1 = cable diagnostic test is enabled. It is
self-cleared after the VCT test is done.
0 = indicates that the cable diagnostic test is
completed and the status information is valid
for read.
Vct_result
[00] = normal condition.
[01] = open condition detected in the cable.
[10] = short condition detected in the cable.
[11] = cable diagnostic test failed.
Vct 10M Short
1 = Less than 10m short.
Reserved
Vct_fault_count
Distance to the fault. The distance is
approximately 0.4m*vct_fault_count.
