Brad noted that the command that was the problem was: Command/Query Sent:*IDN?. This is a clue that the hardware is not set up properly. I will document the procedure to do so for the future.

The main issue here is that the quantum composer software asks the hardware to identify itself to figure out what features are available. This is done first and needs to be done. Without a response, the software falls on its face. No response will be forthcoming if the port is not set up correctly.

The system has to be set up in combination with the router and the software that comes with the hardware before the labview will run. The failure of the *IDN? command is indicative of that.
