This source module makes it possible to stream analog and digital data from National Instruments hardware. The module can acquire data from multiple PXI-based and/or USB-based National Instruments (NI) devices simultaneously. The NIDAQmx module can also be used in tandem with the Neuropix-PXI plugin, to read in analog and digital inputs in parallel with Neuropixels data.

The editor will automatically generate control buttons for each analog and digital input available on the currently selected NI device. Each analog channel contains a channel status toggle button as well as a terminal configuration toggle button. The channel status toggle button is set to on (green) by default for all channels and is intended to enable/disable channels on the fly. Toggling an enabled channel to off (gray) will 'zero-out' the data coming in on that channel.
