Abstract

The invention discloses a multipurpose serial converter which comprises a USB interface, an RS232 interface, a TTL interface and an automatic switching module, wherein the automatic switching module can realize the mutual automatic switching function among the USB interface, the RS232 interface and the TTL interface; the USB interface comprises a USB transceiver, and RS232 interface comprises an RS232 transceiver, a hot-plug function module and an RXD / TXD port automatic switching module I; the TTL interface comprises a TTL transceiver, a power supply anode and cathode automatic switching module and an RXD / TXD port automatic switching module II; and the USB transceiver, the RS232 transceiver and the TTL transceiver are all connected with the automatic switching module. The invention has novel and special design, reliable working performance, simple and convenient use and operation, perfect function, economy and practicability and can effectively solve various problems of inconvenient operation and damaged circuits existing in the practical application processes of the USB interface, the RS232 interface and the TTL interface.

Description

technical field [0001] The invention belongs to the technical field of serial port applications, and in particular relates to a multipurpose serial port converter. Background technique [0002] At present, in various fields of electronic products, serial communication is widely used, and USB, RS232 and TTL interfaces are very commonly used serial ports, especially when designing and debugging circuits, these three serial ports are often used. At present, there are many USB-to-serial devices on the market; the vast majority of serial port converters on the market are conversions between serial ports and network ports. But there is no device that can realize the automatic switching function between USB, RS232 and TTL interfaces, and there is no automatic switching function between the RXD and TXD ports of the RS232 interface and its hot plug function, and there is no RXD that can realize the TTL interface. A simple and reliable design method and equipment for the automatic sw...
