Connection between the DC DUO and the NME
The NME circuit board (AP2) is a separate unit that is secured above the DC DUO
circuit board (AP1) by means of four screws.
Connectors K3 (communication between the boards), K4 (guard inputs and gas
valve output) and K5 (supply voltage for the NME circuit board) provide the electrical
link between the two boards.
