Hello There,
I assume you are using MXI-4 connection. You can monitor your connection using MXI-4 Connection monitor which gets installed when you install VISA driver. You can find a more detailed explanation on the page 2.1 of the MXI-4 User Manual. I've included a link to the VISA download page below.
