Description

Technical Field

[0001] The present invention relates to the field of electronic technology, in particular to a multi-mode communication output device. Background Art

[0002] A communication output device, or communication controller, is a communication interface device used to control data transmission in a data communication system. It connects the data circuit to the host and is responsible for managing the input and output of data to the host or computer network. This device can convert the computer's parallel data into serial data transmitted on the communication line and perform all necessary control functions, error detection and synchronization. Modern communication controllers also have data compression, routing and security functions, while collecting management information.

[0003] Existing communication output devices have various communication modes. Some communication output devices can only output different communication protocols based on fixed communication connectors and cannot match different interfaces of the same communication. The communication output port of the current communication output device has too many cables, which is not convenient for connection and extraction. When the device needs to change the communication mode, the cable needs to be re-extracted and inserted into the interface, which leads to low efficiency and high cost. Summary of the invention
