  • Page 18: Analog Input

    Signal I/O One 68-pin connector provides access to the 16SE/8DE analog input channels, 24 digital I/O lines, counter/timer channels, and analog outputs (when applicable). With exception of DaqBoard/3006, a HDMI connector is also located on the orb. The HDMI provides connection for channel expansion with the PDQ30.
  • Page 19 Another synchronous mode allows digital inputs to be scanned every time an analog input channel is scanned. For example, if eight analog inputs are scanned at 1 µsec per channel continuously, and 24 bits of digital inputs are enabled, then the 24 bits of digital inputs will be scanned at 24 bits per 1 µsec. If counters are enabled in this mode, they will be scanned at once per scan, in the same manner as in the first example above.
  • Page 20 Example 2: Analog channel scanning of voltage and temperature inputs The figure below shows a more complicated acquisition. The scan is programmed pre-acquisition and is made up of 6 analog channels (Ch0, Ch2, Ch5, Ch11, Ch22, Ch23.) Each of these analog channels can have a different gain.
  • Page 21 Example 3: Analog and digital channel scanning, once per scan mode The figure below shows a more complicated acquisition. The scan is programmed pre-acquisition and is made up of 6 analog channels (Ch0, Ch2, Ch5, Ch11, Ch22, Ch25) and 4 digital channels (16-bits of digital IO, 3 counter inputs.) Each of the analog channels can have a different gain and each of the counter channels can be put into a different mode (totalizing, pulsewidth, encoder, etc.) The acquisition is triggered and the samples stream to the PC via DMA.

  • Page 23: Bus Mastering Dma

    Bus Mastering DMA The DaqBoard/3000 series supports Bus Mastering DMA. Multiple DMA channels allow analog and digital/counter input data, as well as analog and digital output data to flow between the PC and the DaqBoard/3000 series without consuming valuable CPU time. The driver supplied with the DaqBoard/3000, as well as all other third-party software support such as LabVIEW®, automatically utilize Bus Mastering DMA to efficiently conduct I/O from the PC to the DaqBoard.

    Variable pre-trigger with post trigger stop event. Unlike the previous pre-trigger modes, this mode does not have to satisfy the pre-trigger number of readings before recognizing the trigger event. Thus the number of pre-trigger readings acquired is variable and dependent on the time of the trigger event relative to the start.

  • Page 25: Digital Outputs And Pattern Generation

    Digital Inputs and Outputs Twenty-four TTL-level digital I/O lines are included in each of the DaqBoard/3000 Series boards. Digital I/O can be programmed in 8-bit groups as either inputs or outputs and can be scanned in several modes (see Input Scanning). Ports programmed as input can be part of the scan group and scanned along with analog input channels, or can be asynchronously accessed via the PC at any time, including when a scanned acquisition is occurring.

  • Page 26: Counter Inputs

    This example has all 4 DACs being updated and the 16-bits of digital IO. These updates are performed at the same time as the acquisition pacer clock (also called the scan clock.) All 4 DACs and the 16-bits of pattern digital output are updated at the beginning of each scan. Note that the DACs will actually take up to 4 us after the start of scan to settle on the updated value.

  • Page 50: Debounce Module

    Trigger After Stable Mode In the “Trigger After Stable” mode, the output of the debounce module will not change state until a period of stability has been achieved. This means that the input has an edge and then must be stable for a period of time equal to the debounce time.
  • Page 51 T2 – During time period T2, the input signal is not stable for a length of time equal to T1 (the debounce time setting for this example.) Therefore, the output stays “high” and does not change state during time period T2. T3 –...
  • Page 52 Use trigger before stable mode when the input signal has groups of glitches and each group is to be counted as one. The trigger before stable mode will recognize and count the first glitch within a group but reject the subsequent glitches within the group if the debounce time is set accordingly. The debounce time should be set to encompass one entire group of glitches as shown in the following diagram.

  • Page 53: Terms Applicable To Counter Modes

    Terms Applicable to Counter Modes The following terms and definitions are provided as an aid to understanding counter modes. Gating: Any counter can be gated by the mapped channel. When the mapped channel is high, the counter will be allowed to count, when the mapped channel is low, the counter will not count but hold its value.

  • Page 54: Counter/Totalize Mode

    Encoder Mode OPT[1:0]: Determines the encoder measurement mode: 1X, 2X, or 4X. OPT2: Determines whether the counter is 16-bits (Counter Low); or 32-bits (Counter High). OPT3: Determines which signal latches the counter outputs into the data stream going back to the /3000 Series board.
  • Page 55 An explanation of the various counter options, depicted in the previous figure, follows. COUNTER: OPT0: This selects totalize or clear on read mode. Totalize Mode – The counter counts up and rolls over on the 16-bit (Low Counter) boundary, or on the 32-bit (High Counter) boundary.

  • Page 56: Period Mode

    Period Mode TIP: When using a counter for a trigger source, it is a good idea to use a pre-trigger with a value of at least 1. The reason is that all counters start at zero with the initial scan; and there will be no valid reference in regard to rising or falling edge.
  • Page 57 PERIOD: OPT[1:0]: Determines the number of periods to time, per measurement. This makes it possible to average out jitter in the input waveform, sampling error, noise, etc. There are four options: (1) The channel’s measurement is latched every time one complete period has been observed. (2) The channel’s measurement is latched every time that 10 complete periods have been observed.

  • Page 59: Pulsewidth Mode

    Pulsewidth Mode TIP: When using a counter for a trigger source, it is a good idea to use a pre-trigger with a value of at least 1. The reason is that all counters start at zero with the initial scan; and there will be no valid reference in regard to rising or falling edge.
  • Page 60 PULSEWIDTH: OPT2: Determines whether the pulsewidth is to be measured with a 16-bit (Counter Low), or 32-bit (counter High) counter. Since pulsewidth measurements always have the “stop at the top” option enabled, this option dictates whether the measurement has a range of 0 to 65535 ticks, or 0 to 4,294,967,295 ticks.

  • Page 61: Timing Mode

    Timing Mode TIP: When using a counter for a trigger source, it is a good idea to use a pre-trigger with a value of at least 1. The reason is that all counters start at zero with the initial scan; and there will be no valid reference in regard to rising or falling edge.
  • Page 62 An Example of Timing Mode The following example represents one channel in timing mode. The time desired is between the rising edge on the input channel and the falling edge on the mapped channel. Zeroes are returned, in the scan, until one complete time measurement has been taken.

  • Page 63: Encoder Mode

    Encoder Mode TIP: When using a counter for a trigger source, it is a good idea to use a pre-trigger with a value of at least 1. The reason is that all counters start at zero with the initial scan; and there will be no valid reference in regard to rising or falling edge.
  • Page 64 Representation of Quadrature Encoder Outputs: A, B, and Z As the encoder rotates, the A (or B) signal is indicative of the distance the encoder has traveled. The frequency of A (or B) indicates the velocity of rotation of the encoder. If the Z signal is used to zero a counter (that is clocked by A) then that counter will give the number of pulses the encoder has rotated from its reference.
  • Page 65 ENCODER: OPT[1:0]: This determines the encoder measurement mode: 1X, 2X, or 4X. ENCODER: OPT3: This determines which signal latches the counter outputs into the data stream going back to the /3000 Series board. Normally, the start of scan signal latches the counter outputs at the beginning of every scan.
  • Page 66 Wiring for 1 Encoder The following figure illustrates connections for one encoder to a 68-pin SCSI connector on a DaqBoard/3000 Series board. The “A” signal must be connected to an even-numbered channel and the associated “B” signal must be connected to the next [higher] odd-numbered channel. For example, if “A”...
  • Page 67 A typical acquisition might take 6 readings off of the 3000 Series board module as illustrated below. The user determines the scan rate and the number of scans to take. Note: Digital channels do not take up analog channel scan time. In general, the output of each channel’s counter is latched at the beginning of each scan period (called the start-of-scan.) Every time the 3000 Series board receives a start-of-scan signal, the counter values are latched and are available to the /3000 Series board.

  • Page 71: Detecting Input Values

    Detecting Input Values All setpoints are programmed as part of the pre-acquisition setup, similar to setting up the analog path, debounce mode, or counter mode setup. Since each setpoint acts on 16-bit data, each has two 16-bit compare values: Limit A (High Limit) and Limit B (Low Limit). These limits define the setpoint window.

  • Page 72: Controlling Analog, Digital, And Timer Outputs

    Controlling Analog, Digital, and Timer Outputs Each setpoint can be programmed with an 8-bit digital output byte and corresponding 8-bit mask byte. When the setpoint criteria has been met, the P2C digital output port can be updated with the given byte and mask.
  • Page 73 The setting of a detection window must be done with a scan period in mind. This applies to analog inputs and counter inputs. Quickly changing analog input voltages can step over a setpoint window if not sampled often enough. There are three possible solutions for overcoming this problem: The scan period could be shortened to give more timing resolution on the counter values or analog values The setpoint window can be widened by increasing Limit A and/or lowering Limit B.

  • Page 74: P2C, Dac, Or Timer Update Latency

    P2C, DAC, or Timer Update Latency Setpoints allow DACs, timers, or P2C digital outputs to be updated very quickly. Exactly how fast an output can be updated is determined by the following three factors: scan rate synchronous sampling mode type of output to be updated Example: We set an acquisition to have a scan rate of 100 kHz.

    In the example [upper portion of the preceding figure], the setpoint placed on analog Channel 5 updated DAC1 with 0.0V. The update occurred when Channel 5’s input was less than the setpoint (Limit A). When the value of Channel 5’s input was above setpoint Limit A, the condition of <A was false and DAC1 was then updated with minus1.0V.

  • Page 106 Differential mode Differential mode voltage refers to a voltage difference between two signals that are referenced voltage to a common point. Example: Signal 1 is +5 VDC referenced to common. Signal 2 is +6 VDC referenced to common. If the +5 VDC signal is used as the reference, the differential mode voltage is +1 VDC (+ 6 VDC - +5 VDC = +1 VDC).
