Green Field county stadium is planning to conduct a cricket match between two teams A and B. A large crowd is expected in the stadium as 10000 tickets have already been sold. To fulfill the viewers’ requirements, the match administrators are willing to install large display screens inside the stadium which should display the match “Live” through several cameras installed on different angles in the stadium.

After carefully reading and analyzing the given scenario, tell me “most suitable serial transmission mode” with two strong reasons.

The option mentioned in the answer section is certainly the correct option. And we do not need 4 wire RS-485 here as the half-duplex mode is going to work fine here, as the screen is never going to talk to the server, and hence at a time, it is only required for the receiver to receive and transmitter to transmit. However, you cannot certainly opt for fewer number receivers, and the multidrop option is required. And with RS-422A we are limited to 10, and hence, the best option is RS-485.

The first reason is it's noiseless due to the use of a twisted pair of cables. And the second reason is, the number of receivers can be as high as 32.
