User’s Manual of GSD-800S / GSD-802S / GSD-802PS
•
Pair
The twist pair of the UTP cable. The pair groups as follow:
A (Pin 1,2)
B (Pin 3,6)
C (Pin 4,5)
D (Pin 7,8)
•
Length[m]
When properly terminated, Cable Diagnostics reports the approximate cable
length in meters of each of the four cable pair A, B, C, and D.
•
Status
The cable test results. Possible values are:
•
Proper -
The cable passed the test.
•
Open -
The cable is connected on only one side or there is no cable connected
to the port
•
Short -
A short has occurred in the cable. With 10/100BASE link, the status of
Pair C and Pair D will be “Short”.
•
Abnormal termination –
An
improper termination be detected. Proper
termination of Cat5 cable requires a 100
Ω
differential impedance between
the positive and negative cable terminals. IEEE Std 802.3 allows for a
termination of as large as 115
Ω
or as small as 85
Ω
. If the termination
falls out of this range, it is reported as falls an anomalous termination.

Notice:
Be sure to running the Cable diagnostics with standard Cat 5e or Cat 6 UTP cable. With some of the
UTP cables that not match the standard of Cat 5e, it might cause the 10/100Base link down after the
cable diagnostics.
