Input / Output 4-5MN1904
H Pseudo differential, bipolar (ADCMODE 3): Inputs are used in pairs (0 and 1, 2 and 3, 4 and
5, 6 and 7) to create four differential inputs. Within each pair, the odd numbered input is the
negative input, and the even numbered input is the positive input. The input range is
±2.5V.
H True differential (ADCMODE 5): Inputs are used in pairs (0 and 1, 2 and 3, 4 and 5, 6 and 7)
to create four differential inputs. Within each pair, the odd numbered input is the negative
input, and the even numbered input is the positive input. The input range is ±10V.
When an input is selected to operate in any of the paired modes (1, 3 or 5), the other input of
the pair is automatically configured to the same mode. The differential input is referenced
using the name of the odd numbered input.
ADCMODE 4 can be used to turn off an input. When an input is turned off, the sampling
frequency for the other inputs increases proportionately, to a maximum of 4.5kHz for a single
active input.
See the Mint help file for full information about ADCMODE and analog input configuration.
