Minimum Resistance (Ohm) between Adaptor pins
1 & Screen
8 & Screen
1 & 7
> 100 K
> 100 K
> 2 K
Note
A resistance of 20 Ohms is the maximum allowed when the cable is carrying Ethernet.
A resistance of 60 Ohms is the maximum allowed when the cable is carrying only power to the ODU
(when Ethernet is carried by one of the other ODU interfaces).
Note
Ensure that these resistances are within 10% of each other by multiplying the lowest resistance by 1.
If any of the other resistances are greater than this, the test has failed.
