The instrument is echoing the command. This may be a setting you can change. Otherwise, to get a multi-line response, a simple technique is to just do two reads. The first read terminates after the...

Is it trying to echo back the original command? Do two consecutive VISA reads, one will get the echoed back command, the other will get the response. (If you don't, your buffer will eventually fill up...

SUCCESS! I had to use the BUNDLE trick. I originally had the DAQmx REGISTER function after the task config and before the START. But in all the fumbling around, I had moved it to AFTER the start....

You don't mention it but you are certainly getting a resource reserved error. Search the forum for the message or code or simply fix it by using a single task with multiple channels.

Again, haven't watched the jings because I'm lazy :smileytongue:, but my guess is it's somehow due to the strict typing of the wires. It is because of this strict typing that I always use bundle, with...
