The National Instruments DAQPad-1200 Data Acquisition and Controller for the Parallel Port is a low-cost high-performance DAQ unit that communicates with the PC through the parallel port on IBM PC/XT/AT and compatible computers. The DAQPad-1200 has eight analog input channels that the user can configure as eight single-ended or four differential inputs; a 12-bit successive-approximation ADC; two 12-bit DACs with voltage outputs; 24 lines of TTL-compatible digital I/O; and three 16-bit counter/timers for timing I/O. The DAQPad-1200 is completely software-configurable and self-calibrated. The user never needs to open the unit to set jumpers or adjust trimpots.

The DAQPad-1200 is register- and pin-compatible with the Lab-PC+ multifunction I/O plug-in board. The DAQPad-1200 is EPP compatible with IEEE 1284, a standard for high-performance PC parallel ports. The DAQPad-1200 works with two different parallel port types–the original Centronics or unidirectional port for printers, and the Enhanced Parallel Port (EPP). The DAQPad-1200 has a second parallel port connector for transparent pass-through connection to a standard parallel port device.

The user can power the DAQPad-1200 from the included AC adapter, the optional BP-1 rechargeable DAQPad battery pack, or any 9 to 42 VDC source such as a standard 12 V car battery.

By combining multifunction analog, digital, and timing I/O capabilities in a compact, lightweight unit, the DAQPad-1200 is ideal for portable applications using notebook computers or any PC with a parallel printer port. Because the DAQPad-1200 can take advantage of the high throughput capabilities of the PC parallel port, the unit delivers high-performance data acquisition and control for any application where PC expansion slots are unavailable.
