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 ni.com/info and enter cseriesdoc for information about C Series documentation.

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

f = fM ⎟ 256 s --------------------

n

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.
