Connecting to the Disk Drive Power Connector
Note
The power available on the disk drive power connectors in a computer can vary.
For example, consider using a disk drive power connector that is not in the same power
chain as the hard drive.
4. Replace the computer cover, and plug in and power on the computer.
Industrial DIO Features
The NI 6509 features digital filtering, programmable power-up states,
change detection, and a watchdog timer.
Digital Filtering
You can use the digital filtering option available on the NI 6509 to
eliminate glitches on input data. When used with change detection, digital
filtering can also reduce the number of changes to examine and process.
You can configure the digital input lines to pass through a digital filter and
control the timing interval the filter uses. The filter blocks pulses that are
shorter than half of the specified timing interval and passes pulses that are
longer than the specified interval. Intermediate-length pulses—pulses
longer than half of the interval but less than the interval—may or may not
pass the filter.
