Analog to Digital Conversion Options
2.4.9 Channel Configuration Jumpers
The AIN can operate in either single-ended or differential mode. In differential mode,
the AIN converts the analog voltage difference between two inputs. In single-ended
mode, the AIN converts the analog voltage on one channel with respect to Analog
Ground. If the AIN functions in single-ended mode, 64 input channels are available; if
it functions in differential mode, 32 channels are available.
Table 2-7 describes how jumpers Jl0,
Jll,
J13, and J14 select the input mode.

2.4.10 Analog Input Range
The AIN provides five different input scaling ranges which are selected by jumpers
J5,
J6, J7, J8 and J9 (see Figure 2-4).
Any voltage above the specified range will be given
the
maximum (+ full scale) 12-bit value; any voltage below the specified
range
will be
given the minimum
value
(or - full scale) (see also Section 3.6.l).

how these
options are selected.
