One more thing Steve, I can't remember how early or new your EC2=20 is.   The early instructions had an error in the EC2 to PCM=20 connections.  Corrected instruction were sent to all affected = users.
The version in error showed pin 10 on EC2 going to pin 10 on the=20 PCM.   Check this out and make sure it's not in error.
