Configuration
The NI 6509 device is completely software configurable, soit is not necessary to set jumpers for I/O configuration. The PCI-6509 device is fully compliant with the PCI Local Bus Specification, Revision 2.2, and the PXI-6509 device is fully compliant with the PXI Hardware Specification, Revision 2.1. The PCI/PXI system automatically allocates all device resources, including the base address and interrupt level. The device base address is mapped into PCImemory space. It is not necessary to perform configuration steps after the system powers up. 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 troubleshootingguidelines. • Verify that you are using the correct version of NI-DAQ (NI-DAQ 7.1 or later). To download the most recent National Instruments drivers, go to ni.com/drivers. Press to refresh the MAX window, or close and re-open MAX. Reboot the computer. Power off and unplug the computer or chassis, and install the device in a different slot. Refer to the DAQ Getting Started Guide for installation...
