Planet GSD-802PS [72/87] Ω differential impedance between the positive and negative cable terminals ieee std 802 allows for a termination of as large as 115ω or as small as 85ω if the termination falls out of this range it is reported as falls an anomalous termination

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 115Ω or as small as 85Ω. 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.
