The Beam Conditioning Unit comes together with a modular controller. Depending on the possibilities available on the beamline facility more or less tasks can be integrated in the controller.

The controller is equipped with a RS232 interface for control of the different units. With simple commands, which also can be sent from SPEC, the BCU can be addressed. Most signals and controls are also accessible via BNC TTL connectors directly on the back panel of the controller.
