Obs. The following design changes were implemented:
-soldered 180 Ohm-0402 resistors between pins 2 & 3 of U10 and
U11 on the component side(Sch. 5);
-pins 1 & 2 and 11 & 12 of U21 and U22 were lifted from the
pads and crossed (Sch. 7);
-on each connector NIM0, NIM1, NIM2, NIM3 a 50 Ohm-0805 resistor was
soldered between the hot pin and
GND(connector case) on the solder side (Sch. 7).
