Caution
If you use shielded cabling to connect to a C Series module with
a plastic connector, you must attach the cable shield to the chassis
grounding terminal using 2.1 mm
2
(14 AWG) or larger wire. Attach a ring
lug to the wire and attach the wire to the chassis grounding terminal.
Solder the other end of the wire to the cable shield. Use shorter wire for
better EMC performance.

Info Code emcground.
Internal Real-Time Clock
The cRIO-9063 contains an internal real-time clock that maintains system time when
the cRIO-9063 is powered off. The system clock of the cRIO-9063 is synchronized
with the internal real-time clock at startup. You can set the real-time clock using
MAX, or you can set the clock programmatically using LabVIEW.
Refer to the specifications on
for the real-time clock accuracy
specifications.
Battery
The cRIO-9063 contains a lithium cell battery that stores the system clock
information when the cRIO-9063 is powered off. There is only a slight drain on the
battery when power is applied to the cRIO-9063 power connector. The rate at which
the battery drains when power is disconnected depends on the ambient storage
temperature. For longer battery life, store the cRIO-9063 at a cooler temperature
and apply power to the power connector. Refer to the specifications on
for the expected battery lifetime.
The battery is not user-replaceable. If you need to replace the battery, contact NI.
Refer to the controller specifications on
for information about
battery disposal.
File System
LabVIEW mounts USB devices to the media/sdx1 directory and creates symbolic
links /u, /v, /w, or /x to the media mount point, starting with /u if it is available. To
prevent any file corruption to external storage devices, verify that any file IO
