NuTone NM Series Micro-Controller Board

The Micro-Controller Board in all NuTone NM Series Intercoms seems to be the same board, regardless of the model it is used in.  It seems that the NM100 and NM200 share the same board.  It is unclear at this time if there are any firmware difference between the different application.

This would be the same for the M&S Systems DMC1 and DMC3-4

Time will tell what the most common problems will be for this board.  So far, only the backlight LED's seem to be a common problem - which we can repair.

The LCD Display is very prominent on the board, however we don't except it to be a problem, unless it suffers from some type of physical damage

This board is fully populated with small SMD Surface Mounted components - which makes working on it more challenging
