    Chapter 1 Introduction 1.1 Introduction Thank you for buying the Advantech PCI-1742U PCI card. PCI-1742U is a powerful high-resolution multifunction DAS card with 1MS/s sampling rate and 16-bit resolution, fulfills the needs of most data acquisition appli- cations. PCI-1742U provides 16 single-ended or 8 differential analog input channels, two 16-bit D/A output channels, 16 digital input/output channels, and one 10 MHz 16-bit counter channel.

  • Page 9: Boardid

    1.2.2 BoardID The PCI-1742U has a built-in DIP switch that helps define each card’s unique ID when multiple PCI-1742U cards have been installed on the same PC chassis. The BoardID setting function is very useful when build- ing a system with multiple PCI-1742U cards. With the correct BoardID settings, you can easily identify and access each card during hardware configuration and software programming.

    A signal source without a local ground is also called a “floating source”. It is fairly simple to connect a single-ended channel to a floating signal source. In this mode, the PCI-1742U provides a reference ground for external floating signal sources. Fig. 3-2 shows a single-ended channel connection between a floating signal source and an input channel on PCI- 1742U.

    Low input. Figure 3-3 shows a differential channel connection between a ground-reference signal source and an input channel on the PCI-1742U. With this connection, the PGIA rejects a common-mode voltage V between the signal source and the PCI-1742U ground, shown as V in Figure 3-3.

  • Page 31: Figure 3.4:Differential Connection - Floating Signal

    Figure 3.4 shows a differential channel connection between a floating signal source and an input channel on PCI-1742U. In this figure, each side of the floating signal source is connected through a resistor to the AIGND. This connection can reject the common-mode voltage between the signal source and the PCI-1742U ground.
