Cant add my RMX 4102 power supply to PXIe-8881

Hi there,

I am trying to add my RMX 4102 power supply to my PXIe-8881 under network devices, however when I try to add network device I get the following message 

This is strange because I have confirmed that VISA is installed on the RT controller. I am using NI Linux RT. Anyone know how to add the network devices on here?

Thanks
