Auto RTS Control
Under 1:N communication environment, it is undesirable that multiple devices send data at once, causing electrical collision that leads to an error. In order to prevent this, only one device needs to send data at a time, which means that data I/O control is necessary at certain points. performs automatic toggling by hardware, saving extra programming work.
What is RS485 Echo Mode
The point which is different from the method for RS485 Non-echo mode is that the output signal line by itself is input again to the input signal line. Therefore, it is possible to confirm whether the data sent crashes with the data sent by another terminal or not by reading the echoed data. This operating mode is scarcely used except in some special purposes. On all operation is controlled by hardware circuit so no oper
