Need documentation

Hello,

I just bought the VMA05 module and the test code works well

However I don’t how to use it! ( but I know using arduino!)
do you have documentation or tutorial with an external device assembly example as follow

api.ning.com/files/krQ6LHvqcGrqH … er_bb1.jpg

i don’t identify the pin of the ground for example

The second point is that I have to provide an analog voltage between -10 V and 10V, is it possible with the VMA05?

Thanks a lot for your Help
