Communication is also called serial communication. It refers to the way in which a computer uses a serial port cable to communicate with a single device through an international standard protocol. (Generally, desktop computers have one or two serial port sockets) The basic communication mechanisms of >
and >
are the same. Its advantage is that the communication distance is long, and multiple devices can be networked and managed at the same time. >
The computer serial port can directly read the >
signal, but cannot directly read the >
signal. Therefore, the computer connects multiple >
devices in sequence through the >
converter, and uses polling to communicate with the devices on the bus in turn. >
The connection between the device with the farthest communication distance and the computer can theoretically reach >
meters. It is recommended that the user control it within >
meters, and it can be controlled within >
Within meters is best. If the distance is too long, you can use a repeater. Using a repeater, it can theoretically be extended to >
meters. >
