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 1 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:

Half-duplex mode, and for long-distance with the multidrop facility, as screens only need to receive at a time. And this can be ensured through RS-485 or RS-422A. And with RS-485 repeaters implementation, we can construct very long-distance networks with range even more than 4000 feet. RS-422A supports full-duplex mode, and the number of receivers allowed is merely 10, and hence the best option is RS-485. However, it allows till 4000 feet, and if the number of the camera is around 10 or less, then it can also be used. Though it is not multipoint and works on point to point, which is another limitation with it. Hence, the best option is RS-485.

Explanation:

Mode Name: Half Duplex mode ( RS-485)

Reason 1: These uses twisted-pair comprising of two cables, and these noises in one cable are canceled by noise in second, and we get noiseless output ar receiver end. Also, proper grounding through a single point ensures there is no loop current forming due to the ground voltage. and all the other voltages are always referenced to this ground voltage. In general, also note that Ethernet can be converted to RS-485 through a suitable device to form the final required network. However, here RS-485 alone will work fine.

Reason 2: Very large number of receivers are allowed, and that is around 32. And that is definitely going to solve the purpose here.

Note: even if screens use AI and feedback the video footage in realtime, at a time we will need only one to transmit, and hence, the above will work. However, in case of high accuracy through machine learning, the full-duplex will be required, however, that is not a case here. However, RS-232 provides full-duplex connectivity though it is for very short distances. And seeing the baud rates, a half-duplex does provide a very high level of accuracy. For further information, you can check how CCTV cameras are installed these days, as very high-quality Network interface cards and wires, as well as connectors, are available these days. And briefly, 4 wire RS-485 does support full-duplex communication, but remember, that is not a requirement here. And hence the correct option for this question is as mentioned in the answer section.
