After removing the top cover and the front panel as described previously, remove the three roundhead screws that fix the function card(s) on the standoffs.
Page 15: Theory Of Operation
0.01% accuracy. 3.2. Programmed Conversion The ProDAQ 3411 allows to separately acquire single samples on one channel at a time. By using the ADCconv registers, the control logic will automatically switch the multiplexer to the requested channel and start the ADC conversion. The result can be read through the ADCvalue register.
Page 16: Multiplexed Conversion
ProDAQ 3411 24-Ch. ADC Function Card User Manual 3.3. Multiplexed Conversion To acquire consecutive samples from multiple input channels, the ProDAQ 3411 features a data acquisition mode where the control logic automatically switches the input multiplexer between the enabled channels and moves the converted values of such a scan into the on-board FIFO. The FIFO logic allows generating asynchronous signals to the application when data is available.

ProDAQ 3411 24-Ch. ADC Function Card User Manual 3.3.4. The on-board FIFO The ProDAQ 3411 features an on-board FIFO to buffer the data generated during data acquisition. The FIFO control logic is able to generate signals when the amount of data in the FIFO reaches a certain level.

Figure 7 - Function Card Selection If no ProDAQ 3411 is available in your system, the soft front panel application can be run in demo mode, allowing to operate all controls as if connected to a 3411. After initializing the ProDAQ 3411 function card, during which a splash screen is displayed, the soft front panel window will appear (see Figure 8 - ProDAQ 3411 Soft Front Panel User Interface).

The Graph Controls The graph controls below the data display can be used to change the scaling of the display or the precision of the labels shown. They allow you to zoom in and out for a more detailed display. A cursor can be activated selecting a point in the display by using the left mouse button.
Page 23: Programming The Prodaq 3411
3411-XX-UM 5. Programming the ProDAQ 3411 This chapter shows how to program the ProDAQ 3411 function card using the VXIplug&play driver. Complete examples can be found in the “Examples” subdirectory of the driver. All functions are explained in detail in the help file coming with the driver.
Page 24: Setting Gain And Filter
5.2. Setting Gain and Filter The filter and gain stages on the ProDAQ 3411 function card are configured using the function . It takes as arguments the session to the instrument, a value for the gain bu3411_setFEconf() setting, a value for the filter setting and a flag, which switches on or off the OTD (Open Thermocouple Detection).
Page 25: Acquiring A Waveform
ProDAQ 3411 24-Ch. ADC Function Card User Manual 3411-XX-UM The channel mask is a 32-bit integer, whose first 26 bits are used to specify whether a channel shall be included in the scan or not. Bit 0 represents channel 1, bit 1 channel 2 and so on. Bit 24 represents channel 25, which is connected internally to Ground, and bit 25 channel 26, which is internally routed to the voltage reference bus from the motherboard.
Page 26: Asynchronous Acquisition
5.5. Asynchronous Acquisition To acquire data continuously, the ProDAQ 3411 needs to be configured for scanning the input channels and moving the data into the on-board FIFO. The FIFO memory stores the data until the host computer is ready to read out the data.
