My Silverleaf works well.  The CMP-20 works well.  However. the CMP-20 quit talking to the Silverleaf.  All of the values on the Silverleaf Information page have gone to 0 (Zero).  I unplugged the CMP-20 panel and reattached it, but no change.  The last time out, everything worked.  Any suggestions where to start looking for the missing link?
Thank you for your interest.
