	A high precision phase synchronous clock distribution system is mandatory for generating local RF reference signals in an accelerator complex. The dedicated Bunch Timing System (BuTiS) at GSI performs this function. The accuracy of the realized installation under rough ambient conditions is presented. Procedures for calibration and standardization aspects of system modules are pointed out. Hardware as well as software interfaces of the system are described. The interfacing between GPS and BuTiS are explained.

	From time-to-time, microcontroller- and FPGA-based LLRF electronics devices need maintenance of firmware and configuration data.

Both requirements cover measuring devices that operate under a common operating system as well as modules only addressable by means of GPIOs or their programming interface. For large accelerator systems like in the FAIR project, a Web-based remotely controlled system was designed in close collaboration with two industrial partners. To cover the requirements of the extremely different types of participating modules while remaining flexible for future extensions, the system was designed with a maximum of modularity and a strong focus on high reliability and safety.
