Chapter 1 IntroductionNI PXI-8195/8196 User Manual 1-4 ni.com• The Chip Set GMCH connects to the CPU, DDR2 SDRAM, and video.• The SMB to PXI Trigger provides a routable connection of thePXI triggers to/from the SMB on the front panel.• The Watchdog Timer block consists of a watchdog timer that can resetthe controller or generate a trigger.• The Chip Set ICH6M connects to the PCI, USB, IDE, and LPC buses.• The USB Connectors connect the chip set to the Hi-Speed USB 2.0interface.• The PXI Connector connects the NI PXI-8195/8196 to thePXI/CompactPCI backplane.• The Super I/O block represents the other peripherals supplied by theNI PXI-8195/8196. The NI PXI-8195/8196 has one serial port, and anECP/EPP parallel port.• The IDE block is dedicated PCI-IDE circuitry providing fast ATA-100transfers to the internal 2.5 in. hard drive. The IDE feature is built intothe chip set. The hard drive is 30 GB or larger.• The Gigabit Enet connects to either 10 Mbit, 100 Mbit, or 1,000 MbitEthernet interfaces.• The GPIB block contains the GPIB interface.• The ExpressCard/34 slot accommodates an ExpressCard/34 module.National Instruments SoftwareNational Instruments has developed several software kits you can use withthe NI PXI-8195/8196.NI-DAQ has an extensive library of functions that you can call from yourapplication programming environment. These functions include routinesfor analog input (A/D conversion), buffered data acquisition (high-speedA/D conversion), analog output (D/A conversion), waveform generation,digital I/O, counter/timer operations, SCXI, RTSI, self-calibration,messaging, and acquiring data to extended memory.NI-VISA is the National Instruments implementation of the VISAspecification. VISA is a uniform API for communicating and controllingSerial, GPIB, PXI, VXI, and various other types of instruments. This APIaids in the creation of more portable applications and instrument drivers.For information on writing your own PXI instrument driver with NI-VISA,refer to the NI-VISA Getting Started manual and the readme.txt file inthe NI-VISA directory.
