LeCroy LT344L, MAX, IVI and the Ethernet connection

Howdy!

I've installed the NI's lcltxxxx IVI driver for the LeCroy LT344L scope.

IVI Compliance Package: 4.5

MAX 5.4.0f0

I want to use an ethernet connection, but the "Resource descriptor" selection box does not offer an ethernet resource (see attached picture).

Using LeCroy's ScopeExplorer software confirms a working communication between PC and scope.

I am not using both programm (MAX + ScopeExplorer) at the same time.

Thanks for help!
