VXIbus Slot 0/Non-Slot 0
The VXIpc-700 is configured at the factory to automatically detect if it
is installed in Slot 0 of a VXIbus mainframe. With automatic Slot 0
detection, you can install the module into any VXIbus slot.
You can manually configure the VXIpc-700 for either Slot 0 or
Non-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 without
first reconfiguring it to either Non-Slot 0 or automatic configuration.
Neglecting to do this could result in damage to the device, the VXIbus
backplane, or both.
Figure 4-2. VXIbus Slot Configuration
When the VXIpc-700 is installed in Slot 0, 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. As VXIbus System Controller, the VXIpc-700 also drives the
16 MHz VXIbus system clock by an onboard 16 MHz oscillator.
As required by the VXIbus specification, the VXIpc-700 drives the
10 MHz signal CLK10 on a differential ECL output when installed in
Slot 0. When not installed in Slot 0, the VXIpc-700 only receives the
CLK10 signal.
