Overview
This VI is the NI ELVISmx Instrument Launcher’s Digital Reader for the Mac OS. The Digital Reader uses the digital input functionality on the myDAQ to read high or low signals from the digital I/O lines. This instrument has been adapted from its Windows OS form to work with a Mac OS, and the changes
between these versions are explained below.
Hardware Instructions
This VI interfaces with the myDAQ using the digital in buses. Connect your device via USB and select that from the device list in the VI. You can verify that the Digital Reader is receiving signals by using the NI ELVISmx Digital Writer VI and connecting the I/O ports appropriately.
Executable Instructions
1. First, you must download the NI-DAQmx driver for myDAQ from this link:https://decibel.ni.com/content/docs/DOC-39065.
2. Download the attached file (Digital Reader.zip) and save a local copy on your computer.
3. Once inside the folder, navigate to the Digital reader.app and double click to open.
4. Choose your device from the drop down list and press run.
Changes from Windows Version
This instrument is nearly unchanged from its Windows version. The only difference is that the Help button
does not launch the full LabVIEW Help window.
Disclaimer
This instrument is posted as an example for myDAQ for Mac OS X. While it is not an officially supported part of the DAQmx for Mac OS software, we have found it to work without issue. If you run into any issues apart from those noted above, please let us know by posting below.
