  • Page 28: Data Format

    In software, the analog input value is returned as a code. To convert the code to voltage, use the information in the following subsections. Note: When the DT9820 Series function module is above range, the value FFFFFFh (plus full-scale) is returned. When the DT9820 Series function module is below range, the value 000000h (minus full-scale) is returned.

  • Page 29: Converting An Offset Code To A Voltage

    Vin = Code * LSB + Offset where, • LSB is the least significant bit. • FSR is the full-scale range. For the DT9820 Series, the full-scale range is 2.5 for the 0 to 2.5 V range or 2.6 for the -0.10 to 2.5 V range.

  • Page 30: Converting A Twos Complement Code To A Voltage

    Offset Binary where, • LSB is the least significant bit. • FSR is the full-scale range. For the DT9820 Series, the full-scale range is 5.0 V for twos complement coding. • N is the input resolution (24 bits). • Vin is the analog voltage.

  • Page 31: Data Transfer

    Keep the following recommendations in mind when allocating user buffers for continuous analog input operations on the DT9820 Series: • Allocate a minimum of three user buffers. • Specify a buffer size at least as large as the sampling rate; for example, if you are using a sampling rate of 960 Samples/s (960 Hz), specify a buffer size of 960.

  • Page 32: Error Conditions

    This process continues indefinitely until you stop it. Error Conditions The DT9820 Series function modules can report an A/D overrun error if the A/D sample clock rate is too fast. The error occurs if a new A/D sample clock pulse occurs while the ADC is busy performing a conversion from the previous A/D sample clock pulse.
  • Page 33 Principles of Operation • External trigger − Using software, specify the trigger source for the first A/D subsystem (lowest subsystem number) that you want to start simultaneously as an external digital (TTL) trigger. Then, wire the appropriate external digital line, as listed in Table 4 on page 14, to that A/D subsystem.

  • Page 34: Synchronizing The Clocks

    Chapter 2 Synchronizing the Clocks To synchronize the clocks of the A/D subsystems, specify the clock source as the internal A/D sample clock for the A/D subsystems using software. Ensure that you specify the same frequency for the internal clock sources. Then, specify the trigger source for the A/D subsystems as the software trigger.

  • Page 35: Analog Output Features

    The DT9822 module supports two DC-level analog output channels (DAC0 and DAC1). Each DAC is a separate D/A subsystem. Refer to the DT9820 Series Getting Started Manual for information on how to wire analog output signals to the module using the screw terminal panel.

  • Page 36: Output Ranges And Gains

    Chapter 2 Output Ranges and Gains The output range for each DAC is ±5 V. Specify the range using software; set the gain to 1. Conversion Modes DT9822 modules can perform single-value analog output operations only. Use software to specify the range, gain, and analog output channel, then output the data from the specified channel.
  • Page 37 Principles of Operation • Code is the raw count used by the software to represent the voltage. • Vout is the analog voltage. • Offset is the minus full-scale value, or −5 V. For example, if you want to output a voltage of 4.7 V, determine the code value as follows: LSB = 10 V...

    Note: All the digital inputs must be in the high state before the DT9820 Series module can detect a high-to-low transition on the digital input lines. Therefore, if you are using the digital inputs to trigger the A/D subsystems, it is recommended that you do not perform a single-value operation on the DIN subsystem.

  • Page 39: Resolution

    Note: All the digital inputs must be in the high state before the DT9820 Series module can detect a high-to-low transition on the digital input lines. Therefore, if you are using the digital inputs to trigger the A/D subsystems, it is recommended that you do not perform a single-value operation on the DIN subsystem.
