Using This Function
AI_Setup addresses the specified analog input channel and changes the input gain to the
specified gain setting.
AI_Setup, in conjunction with AI_Check and AI_Clear, is used for
externally timed A/D conversions. If your application calls
AI_Read with channel and gain
parameters different from those used in the last
AI_Setup call, you must call AI_Setup
again for
AI_Check to return data from the channel you want at the selected gain.
Note
This function cannot be used if you have an SC-2040 connected to your DAQ
device.
