ACAENV785 provides a Tcl driver that has a fixed initialization of the CAEN V785 module. I believe this was written originally by Scott Williams for the REA3 beamline diagnostics box and initialization does not set the module up to do any zero suppression. Thus, you can expect the data from the module to include all channels fromt he module as well as the standard header and trailer for any event in which the module received a gate.
The adc is more flexible and recommended for use instead. This driver is provided only to support legacy applications.
