Abstract

The invention discloses a state indicating circuit for a computer serial interface, and relates to the technical field of computer equipment manufacturing. A first resistor, a second resistor, a third resistor and a fourth resistor are connected in series; a connecting wire between the first resistor and the second resistor is connected with a base electrode of a first triode; a collector electrode of the first triode, a six resistor and a second light-emitting diode are connected in series; an emitter electrode of the first triode is connected with a grounding terminal; a connecting wire between the third resistor and the fourth resistor is connected with a base electrode of a second triode; a collector electrode of the second triode, a first light-emitting diode and a fifth resistor are connected in series; an emitter electrode of the second triode is connected with an anode of a power supply; and a connecting wire between the second resistor and the third resistor is connected with a signal line connected with the serial interface. The state indicating circuit for the computer serial interface, which is disclosed by the invention, can solve the problem that a working state of the computer serial interface is not indicated.

Description

technical field [0001] The invention relates to the technical field of computer equipment manufacturing, in particular to an indicating circuit for the working state of a computer serial interface. Background technique [0002] Computers are becoming more and more popular in today's society, but there is no indication of the working status of the computer's serial interface. Contents of the invention [0003] The purpose of the present invention is to provide a computer serial interface state indication circuit, which can solve the problem that the computer serial interface has no indication of the working state. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: the computer serial interface state indication circuit includes a first resistor, and the first resistor, the second resistor, the third resistor and the fourth resistor are connected in series, and the The connecting line between the first resistor and the ...
