Chapter 4 VXIpc 700 Series Configuration and InstallationVXIpc 800/700 Series User Manual4-4 ©National Instruments CorporationRemove the top cover by removing the 10 screws that attach it to themodule.VXIbus Slot 0/Non-Slot 0The VXIpc-700 is configured at the factory to automatically detect if itis installed in Slot 0 of a VXIbus mainframe. With automatic Slot 0detection, you can install the module into any VXIbus slot.You can manually configure the VXIpc-700 for either Slot 0 orNon-Slot 0 operation by defeating the automatic-detection circuitry.Use the five-position jumper W1 to select automatic Slot 0 detection,Slot 0, or Non-Slot 0 operation. Figure 4-2 shows these three settings.Warning: Do not install a device configured for Slot 0 into another slot withoutfirst reconfiguring it to either Non-Slot 0 or automatic configuration.Neglecting to do this could result in damage to the device, the VXIbusbackplane, or both.Figure 4-2. VXIbus Slot ConfigurationWhen the VXIpc-700 is installed in Slot 0, it becomes the VXIbusSystem Controller. In this role, it has VXIbus Data Transfer Bus Arbitercircuitry that accepts bus requests on all four VXIbus request levels,prioritizes the requests, and grants the bus to the highest priorityrequester. As VXIbus System Controller, the VXIpc-700 also drives the16 MHz VXIbus system clock by an onboard 16 MHz oscillator.As required by the VXIbus specification, the VXIpc-700 drives the10 MHz signal CLK10 on a differential ECL output when installed inSlot 0. When not installed in Slot 0, the VXIpc-700 only receives theCLK10 signal.W1a. Manual Non-Slot 0ConfigurationW1b. Automatic Slot 0Detection (Default)W1c. Manual Slot 0Configuration
