MSolutions DC Resistance

Using the MS-TestPro DC Resistance and Looper modules, you can test the DC resistance of CATx cables, and check their ability to provide a sufficient level of PoH (Power over HDBaseT) powering.
 
The DC Resistance module is inserted into the lower slot in the MS-TestPro main unit, while the CATx cable is connected to the DC Resistance module at one end, and to the Looper module at the other end, as depicted in the figure below:
 
 
 
To test the DC Resistance of a CATx cable:

Easily done via the MS-TestPro From the Tools page, in the DCR DC Resistance button.

The DC Resistance can test:
  • Loop Resistance
  • Parallel DC Resistance Unbalanced
  • Pair to Pair Resistance Unbalanced
Loop Resistance – represents the DC loop resistance (in ohms) of a cable, and is calculated as the sum of the DC resistance of the two conductors in a pair.

Resistance of under 20 ohms indicates that the pair should be capable of delivering the minimum of 80% of the power to the remote side.
 
 
 
Parallel DC Resistance Unbalanced displays the parallel resistance of the CATx two conductors in each cable pair. For each pair, the difference is expressed in ohms, as shown in the figure below
 
 
 
Pair-to-Pair Resistance Unbalanced displays the difference in DC resistance between the four pairs in the cable. For each pair, the difference is expressed in ohms, as shown in the figure below.
A difference of under 0.2 ohms or 5% (the higher between the two) indicates that the pair should be capable of delivering the required common-mode current needed to effectively support PoH (PoE) and data transmission over the pair.
 
 
 
You can export your results in CSV format report, and also Save them locally.
