Interesting. Roughly what I expected to be in there. The 5-pin chip is an unregulated charge pump used for inverting the + 5V from USB to -5V. The smaller ones on the other side of the board are indeed some diodes and two resistors. They are used for providing power to the data lines.
Ok so if I understand correctly the ML power box only deliver the 0.25/-0.25V for the datalines and not the higher voltages on the pink and blue wires?
What could be the reason for not having the supply of the data voltages in the BLC NL/ML? Is it because there can only be one unit providing it in a ML network?
