Informs NI-DAQ of the input mode (single-ended or differential), input range, and input 
polarity selected for the device. Use this function if you have changed the jumpers affecting 
the analog input configuration from their factory settings. For devices that have no jumpers 
for analog input configuration, this function programs the device for the settings you want.

chan is the analog input channel to be configured. Except for the E Series devices, 
the AT-MIO-64F-5, and the AT-MIO-16X, you must set chan to –1 because the same analog 
input configuration applies to all of the channels. For the E Series devices, AT-MIO-64F-5, 
and AT-MIO-16X, chan specifies the channel to be configured. If you want all of the channels 
to be configured identically, set chan to –1. 

Range:

See Table B-1 in Appendix B,

inputMode indicates whether the analog input channels are configured for single-ended or 
differential operation:

0:

Differential (DIFF) configuration (default).
