  • Page 27: Specifying A Single Channel

    The DT9800-EC Series boards do not provide isolated analog ground. The DT9800 Series function modules can acquire data from a single analog input channel or from a group of analog input channels. Channels are numbered 0 to 15 for single-ended and pseudo-differential inputs, and 0 to 7 for differential inputs.

  • Page 28: Specifying One Or More Channels

    Specifying Digital Input Lines in the Analog Input Channel List In addition to the analog input channels, the DT9800 Series function modules allow you to read eight digital input lines (Port A, lines 0 to 7) using the analog input channel list. This feature is particularly useful when you want to correlate the timing of analog and digital events.

  • Page 29: Performing Dynamic Digital Output Operations

    Principles of Operation The digital channel is treated like any other channel in the analog input channel list; therefore, all the clocking, triggering, and conversion modes supported for analog input channels are supported for these digital input lines, if you specify them this way. Performing Dynamic Digital Output Operations Using software, you can enable a synchronous dynamic digital output operation for the A/D subsystem.

  • Page 38: Analog Input Conversion Modes

    Chapter 2 Analog Input Conversion Modes DT9800 Series function modules support the following conversion modes: • Single-value operations are the simplest to use. Using software, you can either specify the range, gain, and analog input channel, or you can specify the range and analog input channel and have the software determine the best gain for the range (called autoranging).

  • Page 39: Continuously Paced Scan Mode

    Principles of Operation Continuously Paced Scan Mode Use continuously paced scan mode if you want to accurately control the period between conversions of individual channels in a scan. When it detects an initial trigger, the module cycles through the channel-gain list, acquiring and converting the value for each entry in the list (this process is defined as the scan).

During a continuous analog input operation, the hardware interrupts the firmware on the module when the FIFO is half full. The module then transfers 2048 samples to a circular buffer, which is dedicated to the hardware, in the host computer.

  • Page 60: Internally Cascaded Clock

    C/T clock output signal is 350 kHz. The resulting frequency of the external C/T clock output signal must not exceed 750 kHz. Table 10 on page 48 lists the screw terminals of the DT9800 Series modules that correspond to the external C/T clock signals of each counter/timer.

  • Page 114 Note: The DT9800 Series Calibration Utility is provided for Windows 98, Windows Me, Windows 2000, and Windows XP only. The DT9800 Series function modules are calibrated at the factory and should not require calibration for initial use. It is recommended that you check and, if necessary, readjust the calibration of the analog I/O circuitry on the DT9800 Series function modules every six months.

  • Page 115: Running The Calibration Utility

    Locate the DT9800 Series software program folder on your hard disk. This program folder was created when you installed the DT9800 Series software. Double-click the Calibration Utility icon in the program folder. Select the name of the DT9800 Series function module to configure from the combo box, then click OK.
