Using Thorlabs DPC5500 with Matlab

Has anyone been able to interface the Thorlabs DPC5500 polarization controller with Matlab? The system uses VISA-TCPIP drivers, but after connecting the device, i cannot read any data out of the device. I used the NI I/O Trace application to look at the communications and it seems the viOpenDefaultRM session address is wrong. Is there a way of telling matlab to use specific session addresses? I suspect part of the problem is that matlab is using a generic type visa instrument, and there are no Thorlab instruments. Does anyone know of a good tutorial on how to create a new visa instrument in matlab? any information will be of great help.

I think you need to look at the manual for the thorlabs device and see if the commands you are sending to get the instrument to respond are correct. I usually start with the *IDN? query and see if that works.

Can you point me to the driver you are using? Also if you haven't already, take a look at the documentation on using drivers in MATLAB .
