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 ...
