Switching device

Abstract

An exemplary adapter comprises an input port for connecting to a first hardware device; an output port for connecting to a second hardware device; a standby output port for connecting to the second hardware device; a programmable logic device (PLD) having at least one input terminal connected to the input port, at least one output terminal connected to the output port, at least one standby output terminal connected to the standby output port, and at least one control terminal to receive a voltage signal; and a jumper connected to the control terminal of the PLD to send a voltage signal thereto, wherein the input terminal of the PLD is selectively coupled to the output terminal or the standby output terminal of the PLD under the control of the voltage signal.

Description

technical field [0001] The invention relates to an electronic device, in particular to an adapter device. Background technique [0002] At present, the method of connecting a switching device between two pieces of hardware is often used for signal transmission between the two pieces of hardware. output terminal, the input terminal of the adapter device is connected to the signal output terminal of a hardware, and the output terminal of the adapter device is connected to the signal input terminal of another hardware, so that the signal of the signal output terminal of the first hardware can be It is transmitted to the signal input of the other hardware, but the data line on the conversion device is often short-circuited or disconnected due to pollution with oil, debris, etc., or other reasons, causing some signal transmission failures on the conversion device , in view of this situation, the traditional processing method is to use a spare data line to manually replace the da...

[0002] At present, the method of connecting a switching device between two pieces of hardware is often used for signal transmission between the two pieces of hardware. output terminal, the input terminal of the adapter device is connected to the signal output terminal of a hardware, and the output terminal of the adapter device is connected to the signal input terminal of another hardware, so that the signal of the signal output terminal of the first hardware can be It is transmitted to the signal input of the other hardware, but the data line on the conversion device is often short-circuited or disconnected due to pollution with oil, debris, etc., or other reasons, causing some signal transmission failures on the conversion device , in view of this situation, the traditional processing method is to use a spare data line to manually replace the data line with signal short circuit or open circuit on the adapter device, or directly replace a new adapter device, although these two methods can solve the problem. The problem of short circuit or open circuit of the data line of the transfer device, but the timeliness is poor, and the implementation is cumbersome, resulting in waste of time and cost
