active x to control Array 3700 DC electronic load

[ArturM]

I want to control Array 3700 DC electronic load using LabVIEW.

I have software to this instrument and it works correct. It is connected by USB.

I have installed OCX library. 

in attached file are: ocx library, instruction how to install it and file with installed active x

Has somebody idea how to do it?

I tried something like this but it doesn't work.

on picture is empty place near 'Port'. I raid numbers 1-8 buy it doesn't work. It is probably information about 'COM' where my instrument is connected.

Sorry ArturM, I'm a little unclear as to what your question is.

I recommend reading section two, found at the bottom of this page:

http://zone.ni.com/devzone/cda/tut/p/id/3831

It has some explanation on 'COM' which may help.

Thanks
