Proceeding of the Joint International Symposium on Deformatuon Monitoring. 2-4 November, 2011. Hong Kong. China. Report. The evolution of the measurement equipment, with the incorporation of the electronic, has facilitated the measurement work making possible new ways of operation and use of these instruments. Equipments that enable the search and the automatic target recognition (like robotic total station) are good examples of this improvement. An important feature of most digital equipment is the possibility to connect them to a computer. Currently, that process is performed to download data (main use of this connection), to load data in the equipment's memory or, in specific cases, even to control the equipment through the computer or another device. Today with the Robotic Total Stations is possible to perform a continuous geodetic monitoring work, what is especially interesting in cases where this process need to be done along the time, mainly without stops. one way to get this aim is the automation in the control of the instrument. In this work were studied the way of how to establish the communication and control of these measuring instruments. It's also presented a short review of data transmission and communication and the development of computer programs that allows data transmission between the robotic total station and a computer, and the control of the instrument by a remote station. All the communication interfaces available on the instrument such as serial cable, Bluetooth® and radio link were tested. Also it was studied the communication protocol specific for the instrument used in the tests. The main goal of this work was the development of a computer program that allows the control of a Robotic Total Station (Leica TCRA1205), for the monitoring of a large dam (one kilometer long), where it was fixed a set of reflector prisms in the downstream of the dam.
