Abstract
What is described here is a system for centrally monitoring and/or controlling at least one unit for endoscopy and particularly for minimally invasive surgery, such as an insufflation means, a pump, a light source and/or a video camera, wherein the unit or units to be controlled are interconnected via interfaces.
The inventive system is characterised by the combination of the following features:
the units are connected via the interfaces on a self-configuring bus to a BUS master,
the BUS master configures the bus automatically,
the BUS master monitors the communication on the bus for correct execution.
