NI 9225E Operating Instructions and Specifications

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

and enter

for information about C Series documentation.

The following equation provides the available data rates of the
NI 9225E:

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.
