USB 2.0 Ports
The NI CVS-1459RT has two high-retention USB 2.0 ports. The USB ports support common
USB mass-storage devices such as USB flash drives, USB-to-IDE adapters, keyboards, and
mice.
LabVIEW usually maps USB mass-storage devices to the /U, /V, /W, or /X drive, starting with
the /U drive if it is available. Refer to the
LabVIEW Help
for more information.
Figure 3-5 shows the pinout for the USB connectors.

RS-232 mode. Set the serial port mode in the BIOS. Refer to the
BIOS Configuration and System Recovery
, for more information.
The serial port is a 10-position RJ50 modular jack, which you can connect to serial devices, such
