The USB interface in a range of its advantages has one, sometimes very annoying disadvantage: if the electrical installation is poorly made, the computer transfers the potential of the network zero to the device being connected. This can result in a number of unsympathetic consequences that can be avoided by using the device described in the article. The USB interface systems manufactured by FTDI are widely known and very popular, mainly due to their ease of use. Particularly comfortable - due to the small number of elements necessary to ensure its correct operation - is the FT232R system and it was he who was used in the presented project. The second system used in the presented project is a two-way galvanic separator - the ISO7221 system.
