© National Instruments Corporation 1-1 DAQCard-700 User Manual1IntroductionThis chapter discusses what you need to get started, optional software,optional equipment, how to unpack the DAQCard-700, and safetyinformation for using the device.About the DAQCard-700The DAQCard-700 is a low-cost, low-power AI, DIO, and TIO card forcomputers equipped with a Type II PCMCIA slot. The card has thefollowing features:• A 12-bit, successive-approximation A/D converter (ADC) with16 single-ended or 8 differential analog inputs• 16 DIO channels: eight lines of TTL-compatible digital input and eightlines of digital output• Two 16-bit counter/timer channels for TIO• A MSM82C54 counter/timer integrated circuit, which provides threeintegrated counter/timers• An optional 50-pin I/O connector, which enables you to easily connectall the analog, digital, and timing signals to the cardThe DAQCard-700 is fully software configurable and factory calibrated.The low power consumption of the DAQCard-700 makes the card ideal forportable computers, making remote data acquisition more practical. Thecard requires very little power when operating and has a standby mode thatuses even less power, thus extending the computer battery life.In addition, the low cost of a system based on the DAQCard-700 makesit ideal for laboratory work. The multiple-channel AI capability is usefulin signal analysis and data logging. The 12-bit ADC is suited forhigh-resolution applications such as chromatography, temperaturemeasurement, and DC voltage measurement. The 16 TTL-compatible DIOlines can be used for switching external devices such as transistors andsolid-state relays, for reading the status of external digital logic, and forgenerating interrupts. The counter/timers can be used to synchronizeevents, generate pulses, and measure frequency and time.
