The experiment complexity ranges from test systems, where a single PC is connected to CAMAC via a PC-CAMAC interface, to experiments with several front-end computers and analysis nodes. The system currently runs under [[Linux]], [[MS Windows]], various versions of UNIX, [[OpenVMS|VMS]], [[VxWorks]] and [[MS-DOS]] and can be ported easily to virtually any operating system which supports [[Internet socket|TCP/IP sockets]].

A speed optimized RPC layer is used for data exchange, with which sustained data rates of 980kB/secs ([[10BaseT]]), 8.7MB7 MB/secs ([[100BaseT]]) and up to 98MB/secs ([[Gigabit Ethernet|1000BaseT]]). An integrated slow control system contains a fast online database and a history system. Drivers exist for CAMAC, VME, Fastbus, High Voltage Crates, GBIB and several PC plug-in DAQ boards. A framework is supplied which can be extended by user code for front-end readout on one side and data analysis on the other side. The online data can be presented by [[Physics Analysis Workstation|PAW]] as histograms and N-tuples as well as by [[ROOT]]. A dedicated HTTP server gives fast Web access for experiment control and to access the slow control system including a graphical representation of variable trends (history display).
