© National Instruments Corporation 1-1 DAQCard-700 User ManualChapter 1IntroductionThis chapter describes the DAQCard-700; lists what you need to get started, softwareprogramming choices, and optional equipment; and explains how to unpack the DAQCard-700.About the DAQCard-700Thank you for your purchase of the National Instruments DAQCard-700. The DAQCard-700 isa low-cost, low-power analog input, digital, and timing I/O card for computers equipped with aType II PCMCIA slot. The card contains a 12-bit, successive-approximation ADC with 16single-ended or 8 differential analog inputs, 8 lines of TTL-compatible digital input, and 8 linesof digital output. The DAQCard-700 also contains two 16-bit counter/timer channels for timingI/O. The optional 50 pin I/O connector for the DAQCard-700 enables you to easily connect allyour analog, digital, and timing signals directly to the card. The DAQCard-700 is fully softwareconfigurable and calibrated so that you can easily install the card and begin your acquisitionwithout having to spend time configuring or calibrating the card.The DAQCard-700 ships with NI-DAQ, National Instruments complete DAQ driver whichhandles every function listed on the data sheet for our DAQ hardware. Using NI-DAQ you canquickly and easily start your application without having to program the card on the register level.The small size and weight of the DAQCard-700 coupled with its low-power consumption makethis card ideal for use in portable computers, making remote data acquisition practical. The cardrequires very little power when operating and has a standby mode that uses even less power, thusextending the life of your computer batteries.In addition, the low cost of a system based on the DAQCard-700 makes it ideal for laboratorywork in industrial and academic environments. The multichannel analog input is useful in signalanalysis and data logging. The 12-bit ADC is useful in high-resolution applications such aschromatography, temperature measurement, and DC voltage measurement. The 16 TTL-compatible digital I/O line can be used for switching external devices such as transistors andsolid-state relays, for reading the status of external digital logic, and for generating interrupts.The counter/timers can be used to synchronize events, generate pulses, and measure frequencyand time. The DAQCard-700, used in conjunction with your computer, is a versatile, cost-effective platform for laboratory test, measurement, and control.Detailed specifications of the DAQCard-700 are in Appendix A, Specifications.
