The Instrument Control settings section of the Digital Reader allows the user to select which device they are using to take a measurement and if they’d like to acquire one sample or acquire continuously. This section also holds the run and stop buttons for the Digital Reader and a link to the help section for the Digital Reader in the NI ELVISmx help.
The device drop down selection box allows a user to select any myDAQ or ELVIS unit that is connected to the system. The device list, which includes the device numbers, is pulled from the devices and interfaces that can be seen in Measurement and Automation Explorer. To test or rename each device, see the Configuring and Testing your myDAQ in Measurement and Automation Explorer page.
The acquisition mode drop down selection box gives two options: run continuously, and run once. When run continuously is selected, the Digital Reader will start running as soon as the Run button is pressed, and will continue to make measurements until the Stop button is pressed. When run once is selected from the Acquisition Mode list, the Digital Reader will take a single measurement when the Run button is pressed, and will then stop executing automatically.
