No reason to apologize. There is a learning curve here that we are trying to remove.
The EZIO8SA cannot connect directly to a PC. The EZIO8SA can only communicate on an Insteon network. You configure the EZIO8SA through the insteon network.
To use the free utility you must connect through a PLC or through an EZSrve that is connected to your computer. If you decide to not use the free utility, you need to use a different sw package or use a manual method.
If you decide to use the free utility, you need to purchase one of the above. I am sorry, but we do not have support for the PLM with the utility.
Also, depending on your needs, you can just use a manual configuration, though you are limited in how much you can configure. See the quick start guide.
If you still have more questions, feel free to continue posting or if you are getting impatient you can contact firstname.lastname@example.org or call us (877-495-0144 9AM – 5PM PST).
