Remarks

Device driver software

This filter is intended to cooperate with digital I/O cards using its vendor driver software. To be able to connect to a card it is required to install NI-DAQmx driver software. Currently Aurora Vision Studio requires NI-DAQmx version 23.3.

NI-DAQmx driver software can be downloaded from the following website: https://www.ni.com/pl-pl/support/downloads/drivers/download.ni-daq-mx.html#480879.

Device identification

When there is only one device connected to computer, inDeviceID field can be set to Auto. In this situation first available device will be found and connected.

inDeviceID can be used to pick one of multiple devices connected to computer. Set this field to Device alias (for example "Dev1"), product name or serial number. This parameters should be available in Measurement & Automation Explorer.

Multithreaded environment

This function is not guaranteed to be thread-safe. When used in multithreaded environment, it has to be manually synchronized.
