Ademco mcontrol connection
So I've read on this forumn and to my understanding the best way to connect an Ademco alarm is through the 4100SM. The alarm must be a vista 50p or 100 or 128 or 250.
I've seen the ICM and that seems like it makes sense but it is discontinued. How would you connect the 4100SM most computers don't have a serial connector? I guess you would have to get a USB to serial adapter.
Has the ICM been replaced by something or is there a honeywell alarm that connects to ethernet? Seems like that would be a no-brainer now adays.
