USER GUIDE AND SPECIFICATIONS NI 6509 The NI 6509 is a 96-bit, high-drive digital input/output (I/O) device for PCI, PXI, and CompactPCI chassis. The NI 6509 features 96 TTL/CMOS-compatible digital I/O lines, 24 mA high-drive output, a watchdog timer, digital filtering, and programmable power-up states. -
Page 2: Configuration
Refer to the application software documentation for configuration instructions. After the NI 6509 device and the software are installed, the DAQ device appears under the Devices and Interfaces branch of the MAX configuration tree. If the DAQ device does not appear in MAX, use the following troubleshooting guidelines. -

Digital Filtering Use the digital filter option available on the NI 6509 input lines to eliminate glitches on input data. When used with change detection, filtering can also reduce the number of changes to examine and process. -

(1 to 0) transitions. Programmable Power-Up States At power-up, the output drives on the NI 6509 are disabled. All lines are user-configurable for high-impedance input, high output, or low output. User-configurable power-up states are useful for ensuring that the NI 6509 powers up in a known state. -
Page 9: Change Detection
Change Detection You can program the NI 6509 to send an interrupt when a change occurs on any input line. The NI 6509 can monitor changes on selected input lines or on all input lines. It can monitor for rising edges (0 to 1), falling edges (1 to 0), or both. -
Page 10: Watchdog Timer
In this example, the NI 6509 reports rising edges only on bit 1, falling edges only on bit 0, and rising and falling edges on bits 7, 6, 5, and 4. The NI 6509 reports no changes for bits 3 and 2. After receiving notification of a change, you can read the port to determine the current values of all eight lines. -
