The high resolution spectrograph at TNG (SARG), mounted at the telescope in 2000, is based on the 'first generation CCD controller, transputers and VME real time computer that control the instrument and the detectors. The evolution of the CCD controller, with high performance in speed acquisition and transfer rate, has changed the architecture of the instrument control. Due to the high performances of modern LAN, it has become possible to have direct access to CCD controller and instruments features. The architecture is based on a remote system, connected to a local system through standard network facilities and communicating with it using an XML-like syntax. The remote system receives from the local system commands and, in turn, sends back telemetry and images. This control system will be tested for the first time with the SARG spectrograph, in the framework of the Instruments remote control project at the Telescopio Nazionale Galileo (TNG).
