The syntax used in the DaqMux output stream selection dropbox is one of the following options:

  • 3 parts -> DaqMuxInNum : Source : DAC/ADC used→  X : Y : Z
    1. X
    2. DaqMuxInNum: DaqMux input number
    3. Y: Source of the DaqMux stream
    4. Z: ADC/DAC where that source is connected - intermediate path (Not really important for end users)

...

  • 2 parts → X : Y
    1. X: DaqMux input number
    2. Y: It can be 
      1. a source generated from
        1. the application side (i.e. DBG/Debug, Test)
        2. Unused DAC/ADC port
      2. Disabled

All possible options of the DaqMux input and their descriptions are summarized in Table 1.

5${DEVICE}:DAQMUX${DAQMUX#}_DAQMODEDAQ Mode

Select the data acquisition mode

  • '0' - Trigger mode - Normal DAQ mode.
    • Has to be triggered to start (Other reqs. to start: Enabled, dataValid, tReady, pause).
    • Stream stops if Error occurs.
  • '1' - Continuous mode- The data is framed and continuously streamed out after enabled.
    •  Has to be triggered to start (Other reqs. to start: Enabled, dataValid, tReady, pause).
    • Disable the stream to stop.
    • Freeze buffers inserts flag into the tUser bit at tLast
    • Stream stops if Error occurs.
