Hello! I am upgrading a Vista 20P system that was installed by the prior owner of our house. I am relatively new to this process, and am trying to identify the communicator module that is installed (see attached photos). I am waiting for the ADC-SEM300-VT-VZ to come in-stock so I connect up with alarm.com. Long story short, my questions are:
- What is this module in the pics?
- Can I remove it?
