The analog input section of each AT E Series board is software
configurable. You can select different analog input configurations
through application software designed to control the AT E Series
boards. The following sections describe in detail each of the analog
input categories.
The AT E Series boards have three different input modes—
nonreferenced single-ended (NRSE) input, referenced single-ended
(RSE) input, and differential (DIFF) input. The single-ended input
configurations use up to 16 channels (64 channels on the
AT-MIO-64E-3). The DIFF input configuration uses up to eight
channels (32 channels on the AT-MIO-64E-3). Input modes are
