The VXIpc 870 Series is a custom computer that you install directly in two C-size slots of your VXI mainframe. An embedded computer can take full advantage of the VXI high-performance backplane capabilities and give you direct control of VXI registers, memory, interrupts, and triggers.
Page 17: Standard Equipment
The NI-488.2M software kit gives you access to the industry-standard NI-488.2M software for controlling external GPIB instruments through the GPIB port on the front panel of your VXIpc 870 Series. The GPIB interface on your VXIpc controller is fully compatible with the NI-488.2M driver for a variety of operating systems.

This chapter contains the instructions to configure and install the VXIpc 870 Series. Unless otherwise noted, these instructions apply to all models in the VXIpc 870 Series, which currently consists of the VXIpc-871, VXIpc-872, and VXIpc-873. Electrostatic discharge can damage several components on your VXIpc 870 Caution Series module.
Page 20 Controller device. Installing the VXIpc 870 Series into a slot that does not correspond with the jumper setting can damage the VXIpc 870 Series, the VXIbus backplane, or both. Insert the VXIpc 870 Series in the slot you have selected by aligning the top and bottom of the module with the card-edge guides inside the mainframe.

Configuration Figure 3-2. System Controller Slot Configuration When the VXIpc 870 Series is installed in Slot 0 of a VXI system, it becomes the VXIbus System Controller. In this role, it has VXIbus Data Transfer Bus Arbiter circuitry that accepts bus requests on all four VXIbus request levels, prioritizes the requests, and grants the bus to the highest priority requester.
Page 29: Vxibus Clk10 Routing And Termination
Configuration and Default Settings VXIbus CLK10 Routing and Termination When the VXIpc 870 Series is installed in Slot 0 of your mainframe, it supplies the VXIbus CLK10 signal. The VXIpc 870 Series can use two different sources to generate this signal—an onboard oscillator or the external CLK SMB connector.
Page 30: How To Fix An Invalid Eeprom Configuration
How to Fix an Invalid EEPROM Configuration Use T&M Explorer under Windows NT/9x to edit the configuration of the VXIpc 870 Series. Some of these settings are stored in files that are read by the NI-VXI software, while other settings are stored directly in the VXIpc 870 Series EEPROM.
Page 31: Configuring The Pc
If you encounter this situation you should reduce the size of the VXIpc 870 Series user window. The EEPROM can become corrupted if the VXIpc 870 Series is shut down while it is updating the EEPROM. If this situation occurs after you change the configuration, perform the following steps to reconfigure the VXIpc 870 Series: Turn off your computer.
Page 32: Scsi Termination
SCSI Termination The VXIpc 870 Series uses active termination on the SCSI-3 bus. Because the VXIpc 870 Series is always an end device, you should not need to disable the termination; however, for informational purposes Figure 3-5 shows the jumper settings for both enabled and disabled termination.
Page 33: Cpu Bus Speed
Figure 3-6. System CMOS CPU Bus Speed The VXIpc 870 Series supports CPU bus speeds at 66 MHz and 100 MHz. Under most circumstances 100 MHz delivers the best performance. However, if you want to use a lower bus speed, W4 overrides the 100 MHz setting as shown in Figure 3-7.

Overview, for more information. Installing Additional Memory The VXIpc 870 Series uses 144 pin 100 MHz SDRAM and supports 16, 32, 64, and 128 MB SO-DIMMs for a total of 384 MB maximum. As DRAM technology improves, the maximum amount of RAM supported may increase.
Page 36: Changing The Main Power Fuse
128 MB: National Instruments has tested and verified that the SO-DIMMs we sell work Note with the VXIpc 870 Series. We recommend you purchase your SO-DIMM modules from National Instruments. Other off-the-shelf SO-DIMM modules are not guaranteed to work properly.
Page 37 Chapter 3 Configuration and Default Settings To replace a fuse, do the following: Turn off the VXI mainframe and remove the VXIpc 870 Series module. Using a small flathead screwdriver, turn the fuse holder counter-clockwise until the fuse and holder start to come out of the unit.
Page 38: Developing Your Application
Your software includes several utilities to assist you in your system development. These include T&M Explorer, Resman, NI Spy, VISAIC, and VIC. You can also access several examples to learn how to use NI-VISA or NI-VXI for certain tasks. Each of these components assists you with one of four steps of development: configuration, device interaction, programming, and debugging.
Page 39: Device Interaction
Resource Manager runs. Systems consisting of only a VMEpc 870 Series controller, a VME chassis, and VME boards do not need to run Resman when using NI-VXI software even though the devices do not appear in the T&M Explorer connection tree.
Page 40 Address Map View of T&M Explorer. In this way, you can verify that your VXIpc 870 Series controller can access each of the devices in your system successfully. Alternatively, you can use VISAIC to interact with your devices.

Compiler Symbols for NI-VXI You may need to define some symbols so that the NI-VXI library can work properly with your program. Skip this section if you are programming with NI-VISA only. NI-VISA does not use Note these symbols.
Page 43: Debugging
LabWindows/CVI. VXINT Debugging NI Spy, VISAIC, and VIC are useful utilities that can aid in identifying the causes of problems in your application. NI Spy tracks the calls your application makes to National Instruments T&M drivers including NI-VXI, NI-VISA, and NI-488.2. NI-488.2 users may notice that NI Spy is very similar to GPIB Spy.
Page 44: Functional Overview
VXIpc 870 Series. VXIpc 870 Series Functional Description The VXIpc 870 Series is a VXIbus embedded controller in a C-size form factor. It includes many high-performance peripherals that normally require add-in cards on desktop PCs. In addition, it has a VXIbus interface that is controlled from the PCI local bus, providing extremely high performance and reliability.
Page 45: Processor
Figure 5-1. VXIpc 870 Series Block Diagram Processor The VXIpc 870 Series controllers are based on the Intel Pentium II, Slot 1 architecture. The CPU connects to the motherboard through the 100 MHz GTL+ bus. Because of this modular design, you can easily upgrade your VXIpc 870 Series controller with a new CPU.
Page 46: Agp Graphics
1600 × 1200 256 colors • 10/100 Ethernet and SCSI-3 The Ethernet and SCSI on the VXIpc 870 Series use a Symbios 53C885 dual-function PCI device to connect to 10/100Base Ethernet and Ultra Wide SCSI-3. The Ethernet function has auto negotiation to connect to 10BaseT and 100BaseTX automatically at 10 Mbits/s and 100 Mbits/s.
Page 47: Pci Or Isa Expansion
VXIpc 870 Series is fully compatible with the National Instruments industry-standard NI-488.2 driver for a variety of operating systems. Any software using NI-488.2 will run on the VXIpc 870 Series. Using the high-speed HS488 protocol, the VXIpc 870 Series can transfer data at up to 8 Mbytes/s.
