Bill,

 

The EC2 is sent a command for it to return the data.  Only one devi= ce should be communicating with the EC2 at a time.  The brown and gree= n wires are connected together.

 

The 5V cable works.  I don't know about the 3.3V.

 

If the connection to the EC2 isn't going to be permanent and there is ro= om for the 37 pin break-out connector, it can be used without making a= ny changes to your installation.  This same break-out would be us= ed to access the other signals if you should decide to examine them.
