I received my APEX ASM module, Siemens QPA2000 CO2 sensor from EBAY and the RCA adapter from AMAZON. Wiring was super simple. I just need to verify the correct output is less than 5v. I will be powering this with a 24v from the 832 energy bar.
I know the ASM module is the only one that officially allows analog input from other sensors. But I wonder if the FFM ports could be used the same way?
