Hello,

I try to used the [CVB.NET](http://CVB.NET) SDK with my ImperX camera.  
I am not able to read and write the camera parameters with the following code given in “Getting started with [CVB.Net](http://CVB.Net)”…  
The function “Device.NodeMaps(NodeMapNames.Device)” does not work for me.  
I do not see where the problem is…  
Thanks in advance,

Nicolas

```auto
    Dim _Device As Device = DeviceFactory.Open(foundDevices(1))

    If _Device.NodeMaps.Count > 0 Then
                Dim deviceNodeMap As GenApi.NodeMap = _Device.NodeMaps(NodeMapNames.System)
    End if

```

Hello @Davy54, what error do you get?  
And also you say that NodeMapNames.Device is not working, yet in your code you use NodeMapNames.System.
