Does anyone know how to properly connect the PL-513 to a pic. The PBP manual says 4 connections are required but only 2 pins are used which I assume are zero crossing output wire 1 and x-10 transmit input wire 4. I have tried hooking a 4.7k resistor to 5 volts on all wires, and it didn't work. thanks for all the support. Hopefully I will be able to provide it at some time in the distant future.
