Radionics 6500 receiver overview and programming

This is an overview of the Radionics 6500 security receiver and its programming. This is an older central station receiver used to handle digital signals sent from alarm systems and dialers over telephone lines. The 6500 receiver introduced many features to the alarm industry such as Modem II, Modem IIe, and Modem IIIa2 formats which are still used today. I will be getting a video out on the 6600 receiver, but I am working to get IP reporting functional first.
