  • Page 5: Introduction

    Chapter 1 Thank you for buying the Advantech PCI-1721. The PCI-1721 is an advanced high-speed analog output card for PCI bus, and each of analog output channels is equipped with a 12-bit, double-buffered DAC. It features many powerful and unique functions, like waveform output function with 10 MHz maximum update rate, auto-calibration function and Board ID.
  • Page 6 10MS/s for each analog output channel. Or you can load a cyclic waveform into an on-board FIFO, which will continuously output the cyclic waveform. The on-board FIFO of the PCI-1721 can store 2 to 1024 samples of the waveform. Users can independently set the four outputs to different ranges: 0~+5V, 0~+10V, ±5V, ±10V, 0~20mA or 4~20mA, and all the ranges are...
  • Page 7 Chapter 1 The PCI-1721 has a built-in DIP Switch that helps define each card’s ID when multiple PCI-1721 cards have been installed on the same PC chassis. The board ID setting function is very useful when users build their system with multiple PCI-1721 cards. With correct Board ID settings, you can easily identify and access each card during hardware configuration and software programming.
