Bus termination/connection
When the NME circuit board
is the first or last board in a
network, a short--circuiting link
must be fitted in socket K7.
9.6 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 cir cuit board) provide the electrical
link between the two boards.
