Analog Input

The AIsection of each AT E Series device is software configurable.

You can selectdifferent A I configurations through application software

designed to controlthe AT E Series devices. The following sections

describe in detail each of the AI categories.

Input Mode

TheAT ESeriesdevices 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

configurationusesuptoeightchannels(32channelsonthe

AT-MIO-64E-3).In put modes are programmed on a per channel basis for

multimode scanning. For example, you can configure the circuitry to scan
