All inputs are configured for single - ended, 0 to +5V inputs on power up. Inputs, or pairs of inputs, may be
changed to d ifferential and/or ±2.5 v olt input.
Differential inputs use adjacent channels, as described in Chapter 10, Analog Input, Initialization. Inputs are
pseudo-differential, meaning the input signal is measured with respect to ground. See Chapter 10 for more
information.
