Use the PLM without the passthru outlet as the powerline interface with the Utility, with the one with the passthru outlet connected to the EZIO8SA. If that combination produces the same trace results (different Insteon address of course) it indicates the EZIO8SA is not communicating with whatever PLM it is connected to. Using the PLM with the passthru outlet (which is a 2412S) it is not necessary to use the external power supply with the EZIO8SA as the 2412S provides power. That will eliminate one more variable.
