Slicer + Plus Server Connection Error

Support
1

Hi,
I am attempting to obtain the appropriate transforms for a configuration of NDI markers. I am using the Polaris Vega VT camera, and the Plus Remote module on Slicer. When I launch the Plus server individually, the connection works. But once I launch the Plus Remote module and link the server, I get the following error.

Failed to create IMAGE message - unable to pack image message

Hi, it’s interesting that IMAGE message occurs in your log. If you are only using a position tracker and no imaging device (e.g. ultrasound), then PLUS should not try to create an IMAGE message. Do you want to post the contents of your PLUS config file here?

Yeah, the contents are attached in the below file.

Hello, can we use your .xml file in our laboratory equipment Polaris Vega ST? I tried to load your file in Plus, but it kept giving me an error. As a beginner, I really hope to get help. Thank you very much.
