This chapter introduces a Flash ADC link system for Belle SVD2[1]. The Belle detector was designed and constructed to carry out quantitative studies of rare B-meson decay modes with very small branching fractions using an asymmetric e+e- collider. B-meson decay vertices are measured by a silicon vertex detector (SVD) situated just outside of a cylindrical beryllium beam-pipe. Upgrade of the SVD is SVD2.
The system consists of Flash ADC systems and PCs using PCI/32-bit LVDS parallel interfaces. The role of PC is to read data from the FADC system, to reduce the event data and then to send the event to a computer farm( the destination nodes of event builder) as the source node of event builder system. The PC also should be controlled by a run control system in Belle operator room.
The Flash ADC link system will be constructed by a FADC link project[2].
