Abstract

A device for switching between a serial port straight-through line and a cross line comprises interfaces and a double-pole double-throw switch. The interfaces include a first interface and a second interface, the first interface comprises a first-interface first end and a first-interface second end, a second interface comprises a second-interface first end and a second-interface second end, the first-interface first end is connected with the second-interface first end or the second-interface second end through the double-pole double-throw switch, and the first-interface second end is connected with the second-interface second end or the second-interface first end through the double-pole double-throw switch. The device is simple, reliable, practical and free of damage to a debugging device, and reliability and efficiency of communication debugging are improved.

Description

technical field [0001] The invention relates to the technical field of communication interfaces, in particular to a switching device for serial port direct connection lines and crossover lines. Background technique [0002] With the rapid development of information technology and scientific and technological progress, in many modern centralized management control systems, single-chip microcomputers (single-chip microcomputers) need to be used to achieve various testing and control functions. Single-chip microcomputers are a broad term, which includes many Types, many series, characterized by an integrated circuit chip with the properties of a computer, and has been widely used in various fields. Most single-chip microcomputers have serial ports for communicating with external devices, so that they can easily exchange information with peripherals with serial communication. Most of these devices are connected with serial lines, which are used in device communication. very com...
