  • Page 12: Features

    Chapter 1 Features The DT9835 is a low-cost, high-power, digital I/O module for the Universal Serial Bus (USB). USB is a standard for connecting PCs to peripheral devices, such as printers, mice, and modems, and was developed to make more low-cost ports available for the increasing number of these devices.

  • Page 13: Supported Software

    Supported Software The following software is available for use with the DT9835 modules: • DT9835 Device Driver − This software is provided on the Data Acquisition OMNI CD that is shipped with the module. The device driver allows you to use a DT9835 function module with any of the supported software packages or utilities.
  • Page 14 • Testpoint − Order this optional software package if you want use a drag-and-drop software environment for designing test, measurement, and data acquisition applications. Refer to the Data Translation data acquisition catalog for information about selecting the right software package for your needs.

    When debounce is not selected (the default configuration), a delay of less than 1 ms occurs. Refer to the DT9835 Getting Started Manual for more information. Outputs are open collectors with a 100 kΩ resistor connected to the internal isolated +5 V.
  • Page 21 Principles of Operation You can specify the digital input lines to read in a single-value digital I/O or continuous operation. You can specify the digital output lines to write to in a single-value digital I/O operation. Refer to page 16 more information on digital I/O operation modes.

  • Page 22: Resolution

    Chapter 2 Resolution Using software, specify the number of digital I/O lines to read or write at once by specifying the resolution as 8, 16, 24, or 32. Table 1 shows the effect of resolution on the number of DIN and DOUT subsystems available for a bank.

  • Page 24 Chapter 2 For example, if you specify a resolution of 8, you can read or write to each digital bank separately by specifying element number 0 to 11. If you specify a resolution of 16, you can read or write to two banks at once by specifying element 0, 2, 4, 6, 8, or 10.

  • Page 25: Interrupts

    Principles of Operation Interrupts The DT9835 board can generate a PCI-bus interrupt when any of the digital input lines corresponding to banks 10 and 11 changes state. This feature is useful when you want to monitor critical signals or when you want to signal the host computer to transfer data to or from the module.

  • Page 26: Operation Modes

    Chapter 2 Operation Modes DT9835 modules support the following digital I/O operation modes: • Single-value operations are the simplest to use but do not allow you to check the interrupt status. Use software to specify the DIN or DOUT subsystem, the resolution, and a gain of 1 (the gain is ignored).
