# CatDV Module

This module enables the communication between the CatDV stream nodes and CatDV (Quantum).

The module is easy to set up and requires the following informations:

* IP address of the CatDV server / endpoint
* Port of the CatDV server/endpoint
* Username of the CatDV Admin user
* Password of the CatDV Admin user
* CatDV Version
* SSL mode

Helmut4 currently only supports CatDV v8.

If you are coming from an earlier Helmut4 release (4.0.7 and below), you might see these options in the CatDV Version dropdown. To fix this issue, expand the guideline below.
