Interfacing an xNode and Infinity System with Pliant CrewCom

Updated 4 months ago by Tim Chimes

Scope

To interface your Pliant CrewCom Control Unit with your Infinity system, you will need to connect the I/O from the CrewCom to the xNode. This can be done either with the RJ-45 connectors on the xNode, or the DB-25 connector.

Method 1: RJ-45

Even though these are both RJ-45 connections, they are not straight-through. Because of this, you will likely need to wire up your own cables.

Here is the pinout from the CrewCom 4-Wire RJ-45 connector:

 

And here is the pinout from an Analog xNode:

Because the xNode's I/O are discrete as opposed to be on one connector like on the Pliant device, you will need to split the cable coming from the CrewCom so that is connects to Input 1 and Output 1 on the xNode.

An example pinout for the xNode Input looks like this:

Pliant Pin

xNode Input

Pin 3 (Output +)

Pin 1 (Input +)

Pin 6 (Output -)

Pin 2 (Input -)

An example pinout for the xNode Output looks like this:

Pliant Pin

xNode Output

Pin 4 (Input +)

Pin 1 (Output +)

Pin 5 (Input -)

Pin 2 (Output -)

Method 2: DB-25

Like the RJ-45 ports on the xNode, the DB-25's are discrete. You will need to use both DB-25 connectors if you want bidirectional audio with the Pliant CrewCom system

Here is the pinout in relation to the xNode’s DB-25 connector:
