Hi Jim,

The mode and address must be soldered onto the widget (jumper pads 
provided on the widget for this purpose).  It is assumed that the module 
builder would do this.  It's that assumption that should be documented.  
I say this to bring up the follow-on issue.

The module builder chooses the mode.

The address should be specified by the system administrator since the 
addresses must be unique for each module and the priority is a function 
of the address.  Module builders should give input to the system 
administrator as to what they feel their priority should be, but 
presumably only the system administrator is in a position to know the 
priority requirements of *all* modules and is therefor in a position to 
make these priority (address) decisions.
