    VXIpc-486 Configuration and Installation Chapter 2 Configuring the VXIpc-486 This section describes how to modify the VXIpc-486 Model 500 Series factory configuration. Unless you have special system configuration requirements, you can install and use the VXIpc-486 without altering the factory configuration. Unless you need to alter the configuration shown in Table 2-1, skip the following sections and continue with Installing and Starting Up the VXIpc-486, later in this chapter.

  • Page 19: Configuration Procedure

    Chapter 2 VXIpc-486 Configuration and Installation Configuration Procedure Follow these steps to modify the factory configuration: 1. Ground yourself and the VXIpc-486. The VXIpc-486 can be damaged by static discharge. You are less likely to damage the VXIpc-486 if you place it on a properly grounded anti-static mat and use a wriststrap.

    VXIpc-486 Configuration and Installation Chapter 2 Configuration Options Figure 2-1 shows the location of the VXIpc-486 Model 500 Series configurable components and their physical location relative to some of the major circuit components. The factory jumper settings are indicated in Figure 2-1 by the black rectangles. The jumper headers not shown in Figure 2-1 are not user configurable and should not be populated with shunt jumpers.

  • Page 21: Slot 0 Configurations

    Chapter 2 VXIpc-486 Configuration and Installation Slot 0 Configurations Configurations A through D from Table 2-2 are Slot 0 settings. Do not install the VXIpc-486 in any other slot if you are using any of these four configuration options. Warning: Installing a VXIpc-486 configured for Slot 0 operation into any slot other than Slot 0 can damage the VXIpc-486, the backplane, and the Slot 0 device.

  • Page 22: Modid Signal Termination

    VXIpc-486 Configuration and Installation Chapter 2 MODID Signal Termination W26 configures the MODID signal termination for Slot 0/Non-Slot 0 operation. In the default configuration for Slot 0 operation (Figure 2-2a), W26 causes the MODID signal to be terminated with a 16.9 kΩ pull-up resistor. When configured for Non-Slot 0 operation (Figure 2-2b), W26 causes the MODID signal to be terminated with an 825 Ω...

  • Page 23: Clk10 Generation

    Chapter 2 VXIpc-486 Configuration and Installation CLK10 Generation W24 configures the receiving source for the CLK10 reference. For internal clock generation, leave the jumper in the default position as shown in Figure 2-4a. When the source is from the CLK10 SMB connector on the front panel of the VXIpc-486, set the jumper as shown in Figure 2-4b.

Long or Less While you can physically install a board that is between 8.2 in. and 13.4 in. long into the VXIpc-486, the back end will not be supported inside the VXIpc-486 (see Figure F-7). This may not be an issue in some applications, but if the application requires rugged handling, it may be inadvisable to install the board without a support.

  • Page 58: Figure F-10. First Board 8.2 In. Long Or Less, Second Board Over One Inch Shorter Than First Board

    VXIpc-486 Plug-in Boards Appendix F The second board cannot be supported if it is shorter than the first board by a difference greater than one inch, as shown in Figure F-10. Remember that PC AT-height boards can be used in the second expansion slot only.

  • Page 66: Appendix I Common Questions

    Appendix I Common Questions This appendix answers common questions you may have when using the NI-VXI bus interface software on the VXIpc-486 platform. This material does not cover problems that you may have with the system. Please see Appendix J, Troubleshooting, if you have system-related problems.
  • Page 67 Common Questions Appendix I 4. Make sure that the VXIpc-486 is seated properly in the mainframe. 5. Power on the mainframe and observe whether the SYSFAIL and FAILED LEDs become unlit after running VXIINIT. Refer also to Appendix C, Front Panel Indicators. Why is the TURBO light never lit on the VXIpc-486 Model 500 Series? The TURBO light is never lit on the VXIpc-486 Model 500 Series because models in this series do not have a TURBO or enhanced CPU speed.
  • Page 68 Appendix I Common Questions If I boot the computer without video, and then plug in the video, why it is in black and white? When the computer first boots, the video chips try to synchronize with the monitor. If the monitor is not there, the video chips cannot synchronize and establish color.
  • Page 69 AT keyboard connector to the 6-pin Mini DIN connector. How do I connect a serial device to the COM2/GPIO connector on the VXI-pc486? The easiest way to connect a serial device to the COM2/GPIO connector is to purchase the COM2 adapter cable (part number 182188-01), which brings out the serial port signals from the 15-pin COM2/GPIO connector to a standard 9-pin Subminiature DHD-20 connector.
  • Page 70 Appendix I Common Questions How do I connect an external speaker to the VXIpc-486 to get audio capability? A twisted-pair cable connects the front panel AUDIO/TRG OUT connector to the VXIpc-486 motherboard. By default, this cable is connected to two pins at J17 on the motherboard. With this configuration, TTL trigger signals can be passed out the front panel connector.
  • Page 71 The VXIpc-486 needs upper memory from C800h to CFFFh and from E000h to EFFFh so that it can access the devices in VXI address space. See Appendix G, VXIpc-486 Hardware Configuration for information on the available port I/O register space, upper memory area, interrupts, and DMA channels.
  • Page 72 Appendix I Common Questions How do I view the BIOS setup parameters to check the configuration of the memory, floppy drive, hard drive, time/date, and so on? Follow these steps to view the BIOS setup parameters. 1. Reboot the VXIpc-486. 2.

  • Page 74 The master windows consist of 32 KB and 64 KB blocks of contiguous memory in the PC AT upper memory space that the VXIpc-486 uses to access the VXI/VME bus. The upper memory space of a PC AT is the region from 640 KB (A000h) to 1024 KB (FFFFh). Several system resources, such as system ROM and video memory, reside in this area.
  • Page 75 Appendix J Troubleshooting Why does the VXIpc-486 and/or its installed components (GPIB, COM port) fail to work once ISA bus plug-in cards are installed? The VXIpc-486 and its components use port I/O register space, interrupts, and DMA, just like a desktop PC.
  • Page 76 Troubleshooting Appendix J Caution: You should reformat the disk unless directed by National Instruments support personnel. The HDD controller may have a problem, or a fuse may have blown, causing the HDD to fail. Reformatting the drive prematurely may not fix the problem but could result in a loss of data.
