I want to design a project in which one supervisor 8051 communicates with four other 8051s. I'd like the students to implement this project with some server-client view. That means that the TX port of the main 8051 will be connected to all other 8051s.
I want to make sure that there is no problem with fan out or power. I want all 8051s get the same data but decide if the data for them or not. Is it correct to connect one TX pin to 4 other RX pins without any buffering (and vice versa)?
