To enable communication between devices, there needs to be a bridge connecting the two, which consists of the transmission path and communication protocol. The earliest interface used for device communication was RS232. However, as technology developed, RS232 began to show some limitations, which led to the emergence of new interface standards, one of which is … Read more
