Výroba desky plošných spojů s koaxiálními a běžnými relé, ovládanými pomocí počítače

Abstract

The content of this bachelor thesis is to describe a design and implement a unit of the switching relays, which will be controlled from a computer. The first part describes the theory connection of external devices to your computer. Description of the different communication interfaces including examples for each type of connection. There are also described their advantages and disadvantages. The second part contains a selection of suitable electronic components needed for switching relay via computer. Further calculations are performed parts of the transistor switch and a description of the communication unit to the computer.
