* The analog input signal polarity and full range of PCI9113 have to be set
by using the jumpers (JP1 and JP2) on board. Please refer to the
PCI-9113 user’s manual for the details.
* In PCIS-DDE, each analog input range is represented by an integer. The
valid input ranges and their corresponding integers for PCI-9113 are:
Analog Input Range Represented Integer
±10V 1
±5V 2
±0.5V 7
±0.05V 8
±0.005V 9
±1V 10
±0.1V 11
±0.01V 12
0 ~ 10V 15
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
