I'm trying to do a loopback test to see if I'm successfully reading messages through this serial port connection. So I go to NI MAX>VISA Test Panel to query the message. I've also wired it according to this knowledge base article (only the red wires).

However, when I go to query it I get an error. I also went to my attributes and it says that the attribute 'Is port connected' is not defined or supported by the referenced resource. Can anybody tell me what I'm doing wrong and how I can fix it?
