With the exception of the V862, each of these modules has an N variant (e.g. V785N). The N variants feature NIM inputs and only appear to have 16 channels. In fact they are 32 channel modules with every other channel cabled from the front end to the ADC main board. This can be confusing. The best way to think about the N modules is to ignore figure 4.6 in the manual and to treat it like a 32 channel module for which you are only using channels 0, 2, 4, 6...30. In that way you will understand how to set the channel enables, and thresholds correctly, and unpack the data from the module in a uniform way.
When reading the software documentation, please keep in mind that these modules are built on a common core module, a 32 channel peak sensing ADC with different front end boards that modify the digitization functionality. For example, the V775 has a time to peak converter front end to allow the peak sensing adc core to digitize time. This common core allows a single class, CAENcard, to provide software support for all of the modules described above.
