single interface, and soft front panels provide an interface for testing the functionality of each
instrument with no programming required. NI Switches, DMMs, High-Speed DIO, High-
Speed Digitizers, and Sources each have customized drivers for high-end modular
instrumentation systems. RF applications leverage two drivers, NI-RFSG and NI-RFSA, and
Dynamic Signal Acquisition is available through NI-DAQmx. For more information, visit

You can expand the timing and triggering functionality of your PXI system with PXI Timing
and Synchronization products. These products provide precision clock sources, custom routing
of triggers for multi-chassis synchronization, clock sharing, and more and are programmed
with NI-Sync. For more information, visit

NI-VISA is the National Instruments implementation of the VISA specification. VISA is a
uniform API for communicating and controlling USB, Serial, GPIB, PXI, VXI, and various
other types of instruments. This API aids in the creation of portable applications and
instrument drivers. For information about writing your own PXI instrument driver with
NI-VISA, refer to the
NI-VISA Getting Started Manual
and the
readme.txt
file in the
NI-VISA directory. For more information, visit

.
With LabVIEW for Linux and support for more than two hundred devices on Linux with the
NI-DAQmx driver, you can now create virtual instruments based on the Linux OS. Instrument
control in Linux has been improved by the NI-VISA driver for Linux, and NI modular
instruments are partially supported. For more information, visit

Configuration
BIOS Setup Utility
You can change the PXIe-8821 configuration settings in the BIOS setup program. The BIOS is
the low-level interface between the hardware and operating system software that configures
and tests your hardware when you boot the system. The BIOS setup program includes menus
for configuring settings and enabling PXIe-8821 controller features.
Most users do not need to use the BIOS setup program, as the PXIe-8821 controller ships with
default settings that work well for most configurations.
Caution
Changing BIOS settings may lead to incorrect controller behavior and
possibly an unbootable controller. If this happens, follow the instructions for
restoring default settings in the
System CMOS
section. In general, do
not
change a
setting unless you are absolutely certain what it does.
Accessing BIOS Setup Utility
1.
Power on or restart your PXIe-8821 controller.
2.
When the message
Press <DEL> to enter setup
appears, press the <Delete> key.
The setup program loads after a short delay.
