Apex and Tunze nanostream controllable pumps

Got a quick question, when I hook up the Tunze to the Apex, are there more parts that I need to buy?

This?

All you need is the cable Bogg listed, as long as you have an Apex, not an Apex Lite or Apex Jr. If you have a Lite or Jr, then you'll need a VDM too.

Thanks for the help.
