%X In our approach for developing heterogeneous control
   systems, we have developed a real\-time A/D D/A board called
   "the Raptor". The Raptor communicates over
   high\-speed and highly\-reliable DS\-links (IEEE\-1355). To
   obtain highly accurate analogue conversions, the A/D and D/A
   converteds have a 12\-bit resolution. We measured a maximum
   sampling frequency of 90.5kHz on each A/D channel. The
   maximum sampling frequency of each D/A channel has been
   measured to be approximately 145kHz. For communication with
   the rest of the control environment, two 100Mbit/s DS\-links
   are available. A data transfer rate of 5.57Mbytes/s has been
   achieved on each DS\-link adapter. The Raptor forms a part
   of a heterogeneous multiprocessor closed\-loop control
   environment. This new environment can be used, amongst
   others, for controlling heavy robot applications. The work
   on this environment takes place in scope of JavaPP (Java
   Plug and Play) project. The software will be developed
   together with the CJT\-library that provides inherent
   object\-orientated and parallel design patterns, according
   to CSP paradigm, in Java.
