Each event has Scaler, ADC and TDC "Types", but NOT a DeadT type.
Events are sent to the collector as FR_CAMAC type.
The Dead Time events have DeadT type data, but not the other data types.
DT events are transmitted to the collector as FR_SLOW type.

The VME module is a Motorola processor & has a different "endian"
scheme than the INTEL processors. Byte swapping is done by the Collector.
