National Instruments NI 9233 User Manual

The cRIO-9151 R Series Expansion chassis does 

not support sharing timebases between modules.

This module supports a low-power sleep mode. Support for sleep 
mode at the system level depends on the chassis that the module is 
plugged into. Refer to the chassis manual for information about 
support for sleep mode. If the chassis supports sleep mode, refer to 
the software help for information about enabling sleep mode. Visit 

ni.com/info

 and enter 

cseriesdoc

 for information about 

C Series documentation.

Typically, when a system is in sleep mode, you cannot 
communicate with the modules. In sleep mode, the system 
consumes minimal power and may dissipate less heat than it does 
in normal mode. Refer to the 

 section for more 

information about power consumption and thermal dissipation.
