So, the NX-548E is now compatible with the M1, by using the ELK-WO35A wiring harness. How does it connect to the M1? If I have used up, say, 15 of my 16 on-board ELK zones, and I add the 548, will I need to add anything else (other than the wiring harness) to add some wireless zones? Are there any concerns with going over the 16 first zones? Is there some kind of a one-to-one mapping of wireless zones to elk wired zones? In other words, how does the M1 know which wireless zone is activated? Are there installation instructions for adding the 548 to the ELK somewhere?
