A study of network-based data acquisition system

Network technologies such as Java and Microsoft ActiveX may become powerful tools to construct the distributed and scalable data acquisition system(DAQ). We have developed Java interface to CAMAC and investigated the application of HORB(distributed Java) to the DAQ. We have also evaluated Microsoft OLEautomation technique(OCX) with combining the objects to Excel as the analysis process over network. The possibilities and the scalability of the network distributed DAQ system with test-bed have been also evaluated.
