CI930F-3BDH001010R0005 Communication interface Refers to the physical interface between two communication devices for data transmission and communication. In the computer field, common communication interfaces include serial ports, parallel ports, USB interfaces, etc.

CI930F-3BDH001010R0005 Serial Interface is a common communication interface that transmits data in serial mode, that is, data is transmitted bit by bit in sequence. Serial communication speed is slow, but the transmission distance is long, suitable for remote communication. Common serial ports include RS-232 and RS-485.

CI930F-3BDH001010R0005 Parallel Interface is a parallel data transmission interface, that is, data is transmitted in bytes. The data transmission speed of parallel port is fast, but the transmission distance is short, which is suitable for close-distance data transmission.

USB interface is a universal serial bus interface, it supports hot swap, plug and play. The data transmission speed of the USB interface is fast, the transmission distance is long, and it is suitable for the connection and data transmission of various devices.

In addition to the above common communication interfaces, there are many other communication interfaces, such as Ethernet interface, Bluetooth interface, and so on. Different communication interfaces are applicable to different application scenarios and requirements.
