Question

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, you are required to suggest the “most suitable serial transmission mode” with two strong reasons.

Note: format of your answer should be as follow:



Mode Name:



Reason 1:



Reason 2:

Answer 1

Mode Name: BS-485 Half Duplex Mode 2 wires

Reason 1: less Noisy

Reason 2: Allows upto 32 receivers

Step-by-step explanation:

The BS-485 is an electrical interface, that supports half-duplex mode through 2 wires, and full-duplex mode through four wires. However, here, we only need the half-duplex mode, and that is enough as the recordings are to be shown on the screen, which is the receivers, and they do not need to talk to the transmitter, while the transmitter is transmitting the recordings to the screen. And since, BS-485 supports around 32 receivers, its more than enough for this question requirement. So its half-duplex mode, and an example of the Serial data transmission. And also, it's synchronous, as there is no stop in between the data packets.
