AD824 ID numbers are automatically set by their position in the chain. The first AD824
connected to DME32 is unit #1, and the second AD824 is unit #2, and so on. The IDs have
no relation to the slot number they are plugged into. The ID numbers should be noted and will
be used by the software to address them.
