Description

A kind of 485 translation plates

Technical field

The utility model relates to a kind of translation plate, is specifically related to a kind of 485 translation plates, belongs to and turn over Translate plate technique field.

Background technology

Serial ports is a kind of interface standard, and it defines the electrical standard of interface, the most simply thing One standard of reason layer.It is not specified by the agreement of interface card cable and use, as long as so The interface card cable that we use meets serial ports standard and just can use the most flexibly, Use various agreement to carry out communication in serial interface standard and equipment controls.So the use of 485 Scope is wide, highly versatile, but at present, electronic product on the market also exists different 485 associations The host computer situation about cannot communicate with slave computer of view, so can cause some upper and lower machine it Between cannot mate, so being badly in need of now a kind of 485 translation plates to allow the host computer of two kinds of different agreements Communicate with slave computer.

Utility model content

The technical problems to be solved in the utility model overcomes existing defect, it is provided that a kind of 485 turn over Translate plate, by 485 translation plates, the host computer of two kinds of different agreements can be allowed to communicate with slave computer Get up, and the upper and lower machine of different 485 agreements is without being forced to change by force a wherein side association Discuss and deacclimatize the opposing party, it is only necessary to do translation with this 485 translation plate the most permissible, application Get up to facilitate a lot, different 485 associations can be there are by the electronic product effectively solved on the market The situation that the host computer of view cannot communicate with slave computer, can effectively solve asking in background technology Topic.

In order to solve above-mentioned technical problem, the utility model provides following technical scheme:

The utility model provides a kind of 485 translation plates, including DC-DC power source, 485 translation plates, Upper seat in the plane and lower seat in the plane, described DC-DC power source side is provided with 485 translation plates, and described 485 turn over Translating plate to be electrically connected with DC-DC power source, 24V voltage is transferred to 5V electricity by described DC-DC power source Pressure sends 485 translation plates to, and described 485 translation plates are electrically connected with upper seat in the plane and lower seat in the plane.

The utility model is reached to provide the benefit that: a kind of 485 translation plates, turns over by 485 Translate plate, the host computer of two kinds of different agreements can be allowed to communicate with slave computer, and different The upper and lower machine of 485 agreements without be forced to change by force wherein side's agreement and deacclimatize another Side, it is only necessary to do translation with this 485 translation plate the most permissible, should use and can facilitate a lot, Can the electronic product effectively solved on the market also exist different 485 agreements host computer and under The situation that position machine cannot communicate.

Accompanying drawing explanation

Accompanying drawing is used for providing being further appreciated by of the present utility model, and constitutes the one of specification Part, is used for explaining the utility model, it is right to be not intended that together with embodiment of the present utility model Restriction of the present utility model.
