Quantum Composer Control - The ID Query failed #162

Closed BradSchoenrock closed 5 years ago

BradSchoenrock commented 6 years ago

When trying to set the state of the quantum composer one of several bugs have been short circuited.

This one is The ID Query failed.

Possible reason(s):

The ID Query failed. This may mean that you selected the wrong instrument or your instrument did not respond. You may also be using a model that is not officially supported by this driver. If you are sure that you have selected the correct instrument and it is responding, try disabling the ID Query.

Good luck future me?

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.
