 		 #135327 - Hence "Broadcast only"
Responding to: ???'s previous message
Oleg Sergeev said:
In my opinion, special function of some vendors may utilize strong pull-up to keep noise low as possible. So such connection (in theory) may provide short circuit between active slave transmitted "0" and others slaves which try to keep strong "1" due "off" state.

Could be possible, which is why it should only be done if it's a true broadcast only - ie no response from slaves (so all slave Tx pins are unconnected).
