A multifunctional debugging interface conversion device

Abstract

A multifunctional debugging interface conversion device comprises a parallel interface conversion module, an RS232 conversion module, an RS485 conversion module, a data control module, a mode selection module, a cable clamping machine and a USB (universal serial bus) connector, wherein the cable clamping machine comprises a parallel interface terminal and a serial interface terminal, the mode selection module comprises a dial switch and an encoder, the data control module comprises a control chip and a USBHUB chip, which are connected with each other, the USB connector is connected with the USBHUB chip, a conversion chip of the parallel interface conversion module, a conversion chip of the RS232 conversion module, a conversion chip of the RS485 conversion module and the encoder are respectively connected with the control chip, and the control chip selectively switches on corresponding interface modes according to dial codes of the dial switch. The multifunctional debugging interface conversion device is small and exquisite in appearance, and convenient to bring and use, can achieve conversion between a serial interface mode and a parallel interface mode through the dial switch, meets demands of different debugging interfaces, and can not cause the problems that a device can not be debugged due to the fact that a wrong debugging line is carried when the device is debugged and a worker needs to carry two or three debugging lines for debugging the device.

Description

technical field [0001] The invention relates to an interface conversion device, in particular to a multifunctional debugging interface conversion device. Background technique [0002] With the rapid development of electronic computer technology, all kinds of electronic equipment are more and more widely used in production and life, especially in the aspect of automatic communication, all systems rely on electronic equipment to realize. Device debugging interfaces designed by different manufacturers are different, most of them are serial ports or parallel ports, which require different debugging cables to connect. However, serial ports and parallel ports have multiple interface types and multiple line sequence definitions, and the debugging lines of different manufacturers cannot be guaranteed to be universal. At present, notebook computers are mainly used in equipment debugging. With the upgrading of computer equipment, notebook computers and even desktop computers are rare...

Problems solved by technology

However, there are multiple interface types and multiple line sequence definitions for serial ports and parallel ports, and the commonality between debugging lines from different manufacturers cannot be guaranteed.

At present, notebook computers are mainly used in equipment debugging. With the upgrading of computer equipment, notebook computers and even desktop computers are rarely equipped with serial ports and parallel ports. Use the corresponding serial port or parallel port interface to connect with the manufacturer’s debugging cable. At present, the serial port and parallel port to USB cables are finished lines with fixed interfaces. Once the debugging site finds that the debugging cable does not match the manufacturer’s definition, it cannot be solved.
