* “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.
* “PASBIn” and “PBIn” (n is the bit number) commands are both used for
n-th bit digital data in. For signal bit digital data input, the performance of
these two commands is almost the same. However, for multi-bits digital
data input, using “PASBIn” can get much higher performance than “PBIn”.
Hence “PASBIn” command is especially suitable for multi-bits digital data
input.
