As of this writing the CCU 4-wire outputs will likely connect to an Axia xNode (or xNode2), or other analog to AOIP convertor. The pinouts for xNode connections are below.
Custom RJ45 plug to 1 x XLR3-F and 1 x XLR3-M may be obtained from Pliant or built by the customer. Off-the-shelf StudioHub RJ45 to XLR cables can be used on the xNode side.
It also possible to make cables that provide the cross-wiring for 2 x CCU 4-wire RJ45 plugs directly to 2 x RJ45 plugs for the xNode in and out.
These choices are up to the user.
The pinouts are here just for a quick reference.

NOTE: Sometime in 2026 it is expected that Pliant will have a CrewNet to Dante I/O device. The Dante device will connect to CrewNet and have an AoIP network port as well. Using a Dante Controller or Dante Domain Manager (DDM) a user will be able to connect 4-wires to Infinity directly or using an Infinity Link Gateway.
