Abstract

The invention discloses a network interface and serial port communication switching device. One end of the communication switching device is provided with a UART serial port connected with a computer, while the other end is provided with an RJ45 network interface connected with a liquid crystal television, wherein the sending end of the UART serial port is connected with the receiving end of the RJ45 network interface; and the sending end of the RJ45 network interface is connected with the receiving end of the UART serial port. The invention also discloses a liquid crystal television debugging system. Serial signals of a computer are connected to a CPU of the liquid crystal television through a network cable for debugging, which is convenient, quick and simple.

Description

technical field [0001] The invention relates to the technical field of liquid crystal televisions, and more specifically relates to a network interface and serial port communication conversion equipment and a liquid crystal television debugging system. Background technique [0002] At present, LCD TVs are developing rapidly and have become the main electronic display products for family, entertainment and information presentation. [0003] RJ45, also known as 8J crystal head, refers to a modular jack or plug that is standardized by IEC (60) 603-7 and uses 8 positions (8 pins) defined by international connector standards. The RJ45 interface is small and easy to connect. The Ethernet (Ethernet) interface is RJ45, and the interface connecting the home router and the computer broadband is RJ45. [0004] UART (Universal Asynchronous Receiver / Transmitter, Universal Asynchronous Receiver / Transmitter) serial port is a common debugging interface for the computer host to the LCD TV ...
