My old 2412 PLM has died, so I only have the 2 EZIOcomms. When my computer isn’t plugged into one, I have one plugged into the ISY and the other into the EZIO8SA. I removed the EZIOcomm from the ISY to try and program it, so when using the SHN utility, I’m only using one PLM plugged into one EZIO8SA and the other into the serial port on my computer.
The EZIOcomms have no pass through outlet. There’s no power bars being used. I’ve tried plugging the PLM into different outlets throughout the house with no success.
