National Instruments Software
National Instruments has developed several software kits you can use with
the NI VXIpc-882. NI-VISA and NI-VXI are already installed on your hard
drive; LabVIEW is optional.
Chapter 1 Introduction
NI-VISA is the National Instruments implementation of the VISA
specification. VISA is a uniform API for communicating and controlling
Serial, GPIB, VXI, and VME instruments. This API aids in the creation of
more portable applications and instrument drivers.
NI-VXI is the name of the National Instruments VXI bus control library.
You can create applications using NI-VXI to control both VXI and VME
devices. NI-VXI gives you complete VXI/VME functionality, including
an API for performing basic VXI/VME data transfers and handling
VXI/VME interrupts as well as VXI-specific functionality, such as
doing message-based communication and handling VXIbus triggers.
The NI-VISA/NI-VXI software includes an interactive configuration and
troubleshooting program, libraries of software routines for test and
measurement (T&M) programming, interactive control programs for both
NI-VISA and NI-VXI, a logging utility you can use for debugging your
applications, and a VXI Resource Manager. You can use this software to
seamlessly program multiple-mainframe configurations and have software
compatibility across a variety of controller platforms.
© National Instruments Corporation 1-3 NI VXIpc-882 User Manual
Chapter 1 Introduction
You can also use the National Instruments LabVIEW application program
and instrument drivers to ease your programming task. This standardized
program matches the modular virtual instrument capability of VXI and can
reduce your VXI software development time. This program features
extensive libraries of GPIB, Serial, and VXI instrument drivers written to
take full advantage of direct VXI control. LabVIEW includes all the tools
needed for instrument control, data acquisition, analysis, and presentation.
LabVIEW is an easy-to-use, graphical programming environment you can
use to acquire data from thousands of different instruments, including
IEEE 488.2 devices, VXI devices, serial devices, PLCs, and plug-in data
acquisition boards. After you have acquired raw data, you can convert it
into meaningful results using the powerful data analysis routines in
LabVIEW. LabVIEW also comes with hundreds of instrument drivers,
which dramatically reduce software development time, because you do not
need to spend time programming the low-level control of each instrument.

2. Remove or open any doors or covers blocking access to the chassis
slots.
Caution If the controller is not configured for automatic System Controller detection, be
certain that the slot you select in your VXIbus chassis matches the controller configuration
as either a System Controller device or a Non-System Controller device. Installing the
controller into a slot that does not correspond with the jumper setting can damage the
controller, the VXIbus backplane, or both. Refer to the Slot 0 Detection section of
Chapter 3, Configuration and Default Settings, for jumper configuration information.
3. Insert the controller in the desired slot by aligning the top and bottom
of the controller with the card-edge guides inside the chassis. Slowly
push the controller straight into the slot until its plug connectors are
resting on the backplane receptacle connectors. Using slow, evenly
distributed pressure, press the module straight in until it seats in the
expansion slot. The front panel of the controller should be even with
the front panel of the chassis.

ExpressCard/34
This section provides information on the installation and removal of
ExpressCard/34 modules.
Installing an ExpressCard/34
You can install an ExpressCard/34 module while the NI VXIpc-882 is
running. The NI VXIpc-882 will automatically detect the card.
ExpressCard/34s are generally marked with a symbol or a label to indicate
which end to insert into the slot. The cards are keyed to prevent incorrect
insertion.
To install an ExpressCard/34, complete the following steps.
1. Hold the card so the top side is facing left.
2. Insert the card until it is completely seated in its connector. The
connector has an automatic eject mechanism. If you insert the card and
it is ejected, simply re-insert the card until it is seated.
If you encounter too much resistance, do not force the card. Check the card
orientation and try again.
Chapter 2 Installation
The NI VXIpc-882 will automatically recognize the ExpressCard/34 and
load the appropriate driver(s). Third-party cards may require that you
install additional drivers. Contact your ExpressCard/34 vendor for more
information.
Caution The ExpressCard/34 interface is ESD sensitive. An electrostatic shock on the
ExpressCard/34 module while it is inserted may cause the controller to lock-up or reboot.
Removing an ExpressCard/34
To remove the ExpressCard/34 module push in the module and then release
to eject the card. Slide the card out of the slot.
Caution To avoid data loss and other potential issues, stop communication with your
ExpressCard/34 device before removing it from the NI VXIpc-882. In Windows, use the
Safely Remove Hardware tool to safely stop the ExpressCard/34.

Slot 0 Detection
The NI VXIpc-882 controller is configured at the factory to automatically
detect if it is installed in Slot 0 of a VXI mainframe. With automatic System
Controller slot detection the NI VXIpc-882 controller can be installed in
any VXIbus slot.
The NI VXIpc-882 controller can be manually configured for either System
Controller or Non-System Controller operation by defeating the automatic
detection circuitry. Use the three position jumper J2 as shown in Figure 3-2
to select between automatic detection, System Controller, or Non-System
Controller.

than Slot 0. When installing into a slot other than Slot 0, first reconfigure it as either a
Non-System Controller or for automatic detection. Failing to do so may result in damage
to the NI VXIpc-882 controller and/or the backplane.
When the NI VXIpc-882 controller is installed in Slot 0 of a VXI system it
becomes the VXIbus System Controller. As the System Controller, the
NI VXIpc-882 controller has VXIbus Data Transfer Arbiter circuitry that
accepts bus requests on all four VXIbus request levels, prioritizes the
requests, and grants the bus to the highest priority requester. As the VXIbus
System Controller, the NI VXIpc-882 controller also drives the 16 MHz
VXIbus system clock via an onboard 16 MHz oscillator. As required by the
specification, when installed in Slot 0, the NI VXIpc-882 controller drives
CLK10, a differential ECL output, to the VXIbus backplane. When the
system is not installed in Slot 0 it will only receive the CLK10 signal.
MITE EEPROM
User/Factory Configuration
The EEPROM is divided into two halves—one half is factory configured
and one half is user configurable. Use jumper W5 to control whether the
NI VXIpc-882 controller boots off the factory-configured EEPROM
settings or the user-modified settings. In its default setting, the
NI VXIpc-882 controller boots off the user-configurable half.
This jumper is useful in the event that the user-configured
half of the EEPROM becomes corrupted in such a way that the
NI VXIpc-882 controller boots to an unusable state. By changing this
jumper setting, you can boot to the factory configuration and get up and
running again. Use the procedure as described in the How to Fix an Invalid
EEPROM Configuration section of this manual.

Power-On Self Configuration
The NI VXIpc-882 controller has an onboard EEPROM, which stores
default register values for the VXI circuitry. These values are loaded when
you power up the computer. The values read from the EEPROM program
the PCI interface and the VXIbus registers so that the VXI interface is ready
to respond to Resource Manager accesses within the required 5 seconds of
SYSRST# deasserting.
You can disable this power-on self-configuration (POSC) circuit by
changing switch W8. Although this makes the VXI circuitry unusable,
it is sometimes helpful in debugging address and interrupt conflicts
with add-in boards. In general, however, you should leave W8 in its
factory-default setting. Figure 3-4 shows the possible configurations
for W8.

How to Fix an Invalid EEPROM Configuration
Use MAX under Windows to edit the NI VXIpc-882 controller
configuration. Some of these settings are stored in files that the NI-VXI
software reads, while other settings are stored directly in the NI VXIpc-882
controller EEPROM.
Certain EEPROM configurations, including invalid configurations, can
lock up your computer while it is booting. Generally, only the size and
© National Instruments Corporation 3-7 NI VXIpc-882 User Manual
Chapter 3 Configuration and Default Settings
location of the memory windows can cause the NI VXIpc-882 controller to
lock up your system. For example, many PCI-based computers will not
boot if a board in its system requests more memory space than the computer
can allocate. If you encounter this situation, you should reduce the size of
the NI VXIpc-882 controller user memory window. The EEPROM can
become corrupted if the NI VXIpc-882 controller is shut down while it is
updating the EEPROM.
If one of these situations occurs after you change the configuration,
complete the following steps to reconfigure the NI VXIpc-882 controller.
1. Power off your computer.
Caution To protect both yourself and the mainframe from electrical hazards,
the mainframe should remain off until you finish changing the settings on the
NI VXIpc-882 controller.
2. Change jumper W5 to the position shown in Figure 3-3b to restore the
factory configuration.
3. Power on the computer. The computer should boot this time because
the factory-default configuration is being used to initialize the
NI VXIpc-882 controller.
4. Run your software configuration utility to re-adjust the NI VXIpc-882
controller configuration.
5. After saving the configuration, exit Windows and power off the
computer.
6. Change jumper W5 to the default position, as shown in Figure 3-3a.
7. Power on the computer. If the computer does not boot with this
configuration, you will need to repeat these steps, modifying your
configuration until a final configuration is reached.
VXIbus CLK10 Routing
When the NI VXIpc-882 controller is installed in Slot 0 of your mainframe,
it supplies the VXIbus CLK10 signal. Three different sources for CLK10
are available with the NI VXIpc-882:
• The internal 10 MHz ±50 ppm CLK10 oscillator. This is the default
CLK10 source.
• The front panel CLK10 SMB. When configured as an input the front
panel SMB allows an external source to be used as the source for the
VXIbus CLK10 signal.
NI VXIpc-882 User Manual 3-8 ni.com
• The front panel TRIG/CLK PORT A(B). CLK10 can be routed into the
NI VXIpc-882 from another NI VXIpc-882 through the TRIG/CLK
PORT A(B) on the front panel. Onboard jumpers are used to set this
configuration.
Front Panel SMB Direction Control
W2—SMB CLK10 Direction
This jumper allows you to configure the front panel SMB connector on the
NI VXIpc-882 controller.
The default jumper position, shown in Figure 3-5a, IN, shuts off CLK10 to
the front panel SMB connector. Use jumpers W4 and W3 to configure the
front panel SMB as an input for CLK10. In non-Slot 0 operation the SMB
cannot be configured as an input as only the Slot 0 controller is allowed to
supply CLK10 to the VXI backplane.
Setting the W2 jumper to OUT, as shown in Figure 3-5b, routes the VXIbus
CLK10 to the front panel SMB connector. In non-Slot 0 operation this
jumper will also route the VXIbus CLK10 out of the front panel SMB
connector.

Selecting the CLK10 Source
W3—External CLK10 Source Select
When W4—CLK10 Source Select is set to select an external CLK10
source, W3 is used to select between two external CLK10 sources.
• The default setting, shown in Figure 3-6a, SMB, selects the front panel
SMB connector as the external CLK10 source. There is no need to set
the direction of the SMB with jumper W2 as the controller will set the
SMB as an input for you.
