SysKonnect SK-98xx V2.0 Gigabit Ethernet Adapter
Virtual Cable Tester™ (VCT) 43
The following states of a cable pair are possible after VCT has been executed:
•
Normal cable
The cable pair is connected correctly.
•
Short cable
Two or more cable pairs are short-circuited together. VCT reports the distance to the short-cir-
cuit in meters.
•
Open cable
Lack of continuity between the pins at each end of the twisted-pair cable, i.e. the cable pair is
not connected correctly. VCT reports the distance to the open location in meters.
•
Test failed
The test of the cable pairs was not successful.
•
Impedance mismatch
The impedance on the cable pair is not correct. Possible reasons for impedance mismatch:
•
The cable pair is not connected properly.
• The cable pair is damaged.
• The connector is faulty.
VCT reports the distance to the impedance mismatch in meters.
