Step 1: Evaluating the Configuration with Graphs
There is a voltage drop in a communications cable as current flows through
the cable. The voltage drop increases in proportion to the length of the com-
munications cable and the amperage of the current being carried.
The communications power supply at each node must be 11 V DC min. The
following graph shows the maximum current that can be supplied through var-
ious lengths of cable while maintaining the minimum voltage required at the
nodes. (The values in the graph provide some extra margin.)
