modules must share a single master timebase source. Refer to the
software help for information about configuring the master
timebase source for the NI 9225E. Visit

The following equation provides the available data rates of the
NI 9225E:
f
s
=
where n is any integer from 1 to 31.
However, the data rate must remain within the appropriate data rate
range. Refer to the
Specifications section for more information
about the data rate range. When using the internal master timebase
of 12.8 MHz, the result is data rates of 50 kS/s, 25 kS/s,
16.667 kS/s, and so on down to 1.613 kS/s, depending on the value
of n. When using an external timebase with a frequency other than
12.8 MHz, the NI 9225E has a different set of data rates.
Note The cRIO-9151 R Series Expansion chassis does
not support sharing timebases between modules.
