h . Connect one end of the ring generator’s cable with the 3-pin connectors to the header labeled P101 on the power supply circuit board.

NOTE:

This cable connector, as with all four cable connectors, is “keyed” so that you cannot attach it to the header if it is turned the wrong way.

i . Connect the other end of the cable to the header labeled P1 on the ring generator.

NOTE:

The cable headers, P1 and P101, should be on the same side of the housing, so that the cables do not cross each other.

k.Connect the other end of the cable to the header labeled P2 on the ring generator.

l.Use the clips provided with the ring generator to attach the cables to the inside edge of the plastic housing.
