By the end of this article, you can expect to have been through the generalised troubleshooting steps common to this topic area. By reading through the specific examples, you will know more search terms related to "Flexlogger hardware installation" that can help inspire questions and different ways to look at the problem.

The first step should be to check the Flexlogger Manual for any tools or relevant information regarding installation.

The most common problem is hardware compatibility which can be evaluated from the Release Notes.

Generic Troubleshooting steps:

The following steps follow a methodical approach, each step has an increased level of effort than the previous step.
  1. Verify compatibility of NI-DAQmx, NI-XNET and Flexlogger with the hardware using the relevant Readmes.
  2. Check firewall settings and firmware if using an Ethernet DAQ device
  3. Try uninstalling previous versions linked and used by Flexlogger (e.g. NI-DAQmx or NI-XNET dependencies)
  4. If receiving DAQmx Errors into MAX (like -229771), the MAX Database could be corrupted. Resetting the MAX database can resolve the issue.
  5. Reinstall MAX and DAQmx

  • There can be several issues or errors if using an existing application limited to a previous specific DAQmx or MAX version. It is highly recommended to install the version provided with the current Flexlogger installer. The requirement is the latest version of DAQmx and NI-XNET or higher
