Koncentrátor portů RS-232

Abstract

This thesis deals with the RS-232 concentrator, the concentrator is equipped with one Ethernet and four RS-232. The theoretical part contains a description of the technology. The practical part deals with the first selection and description of the components. The text also mentions a possible alternative components. This makes for a good repeatability of the structure. Subsequently, the proposal described the involvement of individual components and design software designed PCB. The proposal is implemented to allow any further expansion module connected to other ports, RS-232. The proposed hardware is implemented as a sample software that demonstrates the proposed facility. When his work was used pen design environment mikroPascal.
