Wav 1Link Power / Comm Module
It is called 1LINK, because only 1 power adapter is needed, one module (for a maximum of 3 1LINK devices and 2 accessory devices) and a 1-click installation of a cable that not only supplies the product, but also provides the two-way communication to and from your Apex.
Installation is simply click-ready.
eg a 1link product is a wav pump, an accessory product is eg the PMUPv2
