Lionel BPC2 Problems

When you program a BPC2's starting ID (for example: Tr. 1), the Legacy System and LCS are supposed to set the other 7 IDs (Tr. 2-8) automatically, so it's weird that your BPC2 isn't working correctly.

The standard way to troubleshoot this, is to make controlled substitutions of each element in the system until you achieve a working installation.  So you could buy another BPC2 and see whether it does the same thing.  If the new one works, your original one is defective.

That being said, my first recommendation would be a thorough reading of the instructions for all components.  Please let us know what you figure out.

Late to the party here, I don’t know if you got this figured out, my experience is only with the BPC2 built into the CSM2. Should be the same concept. To answer the question yes you should only have to set the first ID then all the other should follow after that.

if 1 works it seams odd the rest wouldn’t just for testing I would put just the BPC2 and the legacy base hooked up, of course power the BPC2 on the AU terminals then try each ID you should hear each relay click if not I’d try reprogramming and try again with the BPC2 as the only LCS device. (Or the second device with the WiFi module)
