* In PCIS-DDE, each analog input range is represented by an integer. The
valid input ranges and their corresponding integer are:
Analog Input Range Represented Integer
±5V 2

±1.25V 4
±0.625V 5
±0.5V 7
±0.05V 8
±0.005V 9
0 ~ 10V 15
0 ~ 5V 16
0 ~ 2.5V 17
0 ~ 1.25V 18
0 ~ 1V 19
0 ~ 0.1V 20
0 ~ 0.01V 21
* “PASAIn” and “PAIn” (n is the channel number) commands are both used
for analog data in. For signal channel analog data input, the performance
of these two commands are almost the same. However, for
multi-channels analog data input, using “PASAIn” can get much higher
performance than “PAIn”. Hence “PASAIn” command is especially
suitable for multi-channels analog data input.
