![]() The simple scheme of this operation is looked like 1 byte = 8 bit = 8 lines (wires) = 1 cycle. That is, to transfer 1 byte of information (8 bits), 8 lines are required, single for each one. In parallel data transmission, each bit is transmitted on a separate line (wire, cable or channel). Let`s look at the principle of their work by transmitting 1 byte (8 bits) of information. OK, we have already received information, so how can it get into the controllers? There are two main ways to transfer such data: For such purpose, simple binary or gray code is used. These values in the form of code are sent to the controllers. How does data transfer work? An example of encodersĪt first, let's find out: where does the data in the encoder come from? Encoders measure the angle of rotation of the offset of its own shaft (rotary) or its scale (linear). Asynchronous data transmission working principle. ![]()
