Issue Details

I received the following error from my real-time target in LabVIEW or Measurement & Automation Explorer (MAX): 
 
VISA Error 0xBFFF00A7 (-1073807193) 
The remote machine does not exist or is not accepting any connections. If the NI-VISA server is installed and running on the remote machine, it may have an incompatible version or may be listening on a different port. 
 

 
 How can I resolve it?
 

Solution

This problem is associated with a VISA setup issue. To troubleshoot, check for the following symptoms:
  1. The remote machine name may be incorrectly specified (either the name was misspelled or the wrong IP address was typed in).
  2. The remote machine may not be turned on.
  3. The VISA server has not been started on the remote machine.
  4. The VISA server was started but is either suspended or is no longer running on the remote machine.
  5. Either the local machine or the remote machine is not connected to the network.
  6. There is a network configuration problem, such as an improperly assigned IP address, an incorrectly configured routing table, or a firewall between the local and remote machine.
If the problem still persists:
  1. Ensure that you have all the correct drivers installed ....
  2. Using the Real Time Software Wizard, remove and reinstall the NI-VISA driver on the controller.
  3. Reset the Controller's IP address.
  4. Check if you have multiple network cards on your computer.  If you do, make sure that the correct ethernet adapter is being used for your controller as detailed in the link.
