2.7.5 PCI VI/O setting
The CP302 provides for either a 5V or 3.3V PCI signaling environment.
The BVI/O power jumpers on the board are used to power the buffers on the peripheral
boards and the PMC interface. The BVI/O does not provide power to the CompactPCI
interface. The CompactPCI VI/O must be configured via the backplane.
2.7.6 Shorting Chassis GND (Shield) to Logic GND
The front panel including the front panel connectors are isolated to the logic ground.
This zero Ohm resistor enables connection between the chassis GND and logic GND.
The default setting is indicated by italics.
