4.2 Analog I/O
The NextMove e 100 provides:
H
Two 12-bit resolution analog inputs.
H
Four 12-bit resolution analog outputs.
4.2.1 Analog inputs
The analog inputs are available on connector X12, pins 1 & 2 (AIN0) and 4 & 5 (AIN1).
H
Differential inputs.
H
Voltage range: ±10 V.
H
Resolution: 12-bit with sign.
H
Input impedance: 120 k Ω .
H
Sampling frequency: 4 kHz maximum, 2 kHz if both inputs are enabled.
The analog inputs pass through a differential buffer and second order low-pass filter with a cut-off
frequency of approximately 1 kHz.
Both inputs are normally sampled at 2 kHz. However, an input can be disabled by setting
ADCMODE
to 4 (
_acOFF
). With one input disabled, the remaining input will be sampled at 4 kHz.
In Mint, analog inputs can be read using the
ADC
keyword. See the Mint help file for full details of
ADC
,
ADCMODE
and other related
ADC
... keywords.
