Internal Real-Time Clock
The cRIO-905
x
contains an internal real-time clock that maintains system time when the
cRIO-905
x
is powered off. The system clock of the cRIO-905
x
is synchronized with the
internal real-time clock at startup. You can set the real-time clock using the BIOS setup utility
or MAX, or you can set the real-time clock programmatically using LabVIEW.
Refer to the model specifications on
for the real-time clock accuracy
specifications.
Digital Routing
The digital routing circuitry of the cRIO-905
x
manages the flow of data between the bus
interface and the acquisition and generation sub-systems when programming C Series modules
in Real-Time (NI-DAQmx) mode. The subsystems include analog input, analog output, digital
