Enumeration Type Documentation

enum DCS::DAQ::ChannelRef

strong

Classifies a channel reference connector for the DAQ.

Enumerator
None	No reference. Will cause an error if used.
Default	Let DAQmx use the default reference for the current channel.
SingleEnded	Use referenced single ended signal.
NoRefSingleEnded	Use unreferenced single ended signal.
Differential	Use differential signal.
PseudoDifferential	Use pseudo-differential signal. See here for more info.

enum DCS::DAQ::ChannelType

strong

Classifies a channel type of the DAQ.

Enumerator
None	No channel.
Voltage	A voltage channel.
Counter	A counter channel. Freq out for outputs.
