Does anyone know the protocol of the Honeywell DG115EZIAQ TrueIAQ sensor system. This is an outdoor temperature/humidity sensor control system. It has a two wire sensor with 24VDC across the pair and a pulsed waveform superimposed upon the DC. I added this question to clarify my needs of my first post "Protocol Analyzer in software?". Thanks in advance.
EDIT: The data is updated once each ~1second. I assume it is a response from the sensor only, however that is just a guess.
