Hard to tell from a typeless language like JS, but I would assume that the following code
var access = WScript.CreateObject("owapi.OneWireAccessProvider");
var adapter = access.getDefaultAdapter();
adapter.beginExclusive(true);
has access as a COM object and adapter as a COM object. If they are declared as such in the type library, then you should get an automation reference for each. Then calling the beginExclusive() method should be straightforward. What are you getting as a wire type for getDefaultAdapter()? I am assuming you are doing Automation Open for the first method...
I went to the website but I don't read Chinese so that is all I know right now.
