En la mayoría de los casos, estos equipos electrónicos se encuentran regulados por las federaciones deportivas internacionales correspondientes. En Cuba los principales estadios de béisbol, disponen de una pizarra electrónica profesional. Estas pizarras necesitan mantenimiento y reparación, sin embargo no existe la suficiente información del fabricante. Igualmente, el software facilitado por el fabricante para el control de estas pizarras no satisface las necesidades de los operadores. En este trabajo se realiza la ingeniería inversa a los distintos módulos de visualización de la pizarra, así como a los protocolos de comunicaciones. Como resultados, se dispone de los esquemas electrónicos, documentación del funcionamiento, así como de los protocolos de comunicaciones. Con estos resultados, se desarrollaron herramientas para pruebas de los módulos de visualización por separado y un nuevo software de control de la pizarra ajustado a las necesidades de los operadores. Adicionalmente se propone una mejor estructura y protocolo, con su respectiva aplicación de software, que reduce la complejidad de interconexión entre los módulos de visualización de la pizarra.]]></p></abstract>

In most cases, these electronic devices are regulated by the corresponding international sports federations. In Cuba, the main baseball stadiums have a professional electronic scoreboard. These scoreboards need maintenance and repair, but there is not enough information from the manufacturer. Likewise, the software provided by the manufacturer for the control of these electronic scoreboards does not satisfy the needs of the operators. In this work, the reverse engineering of the different modules of the scoreboard is carried out, as well as the communication protocols. As results, there are available the electronic schemes, documentation of the operation, as well as the communication protocols. With these results, tools were developed for testing the visualization modules separately and a new control software for the scoreboard adjusted to the needs of the operators. Additionally, a better structure and protocol is proposed, with its respective software application, which reduces the complexity of interconnection between the visualization modules of the scoreboard.]]></p></abstract>
