Abstract:

The JLab Fast Electronic group developed a 16-channel discriminator/scaler VME module. It has scalers and programmable thresholds, digital delays and widths of pulses. Hall-D needs a software to remotely monitor and control these discriminator modules. In this paper the EPICS interface for scaler readout will be described and details of preliminary driver presented.
