NXB-KNX NetLinx NXB-KNX Interface

Overview

The NetLinx NXB-KNX interface (FG2031-01) allows AMX NetLinx Integrated Controllers the ability to control, integrate and communicate with homes and buildings that utilize the KNX communication protocol.

KNX is the world’s first open, royalty free, and platform independent standard for home and commercial building control.

Wiring and Connections

Note: To avoid any damage to the electronic component, installation must be performed in an ESD safe environment.

Note: Do not connect power to the NXB-KNX until the wiring is complete.

The NXB-KNX is installed between the NetLinx Master and the KNX control bus, and passes NetLinx control commands to the KNX control bus via 2-wire twisted pair cabling, as indicated in FIG. 2:

PoE (Power Over Ethernet)

The NXB-KNX uses CAT5/CAT6 wire via the Ethernet port for PoE power.

Use the PS-POE-AF Power over Ethernet Injector (FG423-80) to simplify wiring and installation by eliminating the need for an AC outlet at each point of installation.

Note: The NXB-KNX can be placed up to approximately 330’ (100 meters) from the nearest PoE Injector.

• If used with a non PoE-capable Ethernet switch (such as the NXA-ENET24), then an optional PS-POE-AF Power-over-Ethernet (PoE) power supply is required to provide power to the NXB-KNX.

• If the NXB-KNX is used with a PoE-capable Ethernet switch (such as the NXA-ENET24PoE), then no PoE Injectors are required.

Configuration

NXB-KNX units have a built-in WebConsole that allows you to make various configuration settings via a web browser on any PC that has access to the Master. The web console consists of a series of web pages that are collectively called the "NXB-KNX Configuration Manager".

Determining the IP Address of the NXB-KNX

NXB-KNX units feature a built-in zero-configuration networking client that allows you to determine the unit’s IP address via Bonjour or a similar zeroconfiguration client. Zeroconf (also known as "Bonjour") technology provides a general method to discover services on a local area network. In essence, it allows you to set up a network without any configuration, as described below.

Zero-Configuration (Bonjour) Client

You will need a zero-configuration client to determine the IP address of the NXB-KNX. There are many zero-configuration clients available. However, for the purposes of this document, we will refer to the Bonjour plugin for Internet Explorer. It is free and widely available for download.

If you don’t already have it installed on your PC, download and install Bonjour for Windows before you begin.

Note: The NXB-KNX is set to DHCP by default. Bonjour requires DHCP to discover the device, so don’t change this setting until you have identified the unit on your network.

1. With Bonjour for Windows running on a PC that has access to the LAN that the NXB-KNX resides on, connect the NXB-KNX to the network (see the Wiring and Connections section).

2. In Bonjour, you will see the unit join the network at power up.

3. In Bonjour, click on the NXB-KNX link and it will access the unit's Configuration Manager (IP Settings page).

4. The unit’s IP Address is displayed in the IP Settings page.

At this point you can assign a new IP Address if necessary.

Accessing the WebConsole

From any PC that has access to the LAN that the NXB-KNX resides on:

1. Open a web browser and type the IP Address of the target NXB-KNX unit in the Address Bar.

2. Press Enter to access the WebConsole for the specified NXB-KNX unit. The initial view is the IP Settings page.

Admin Menu

There are several configuration pages included in the Configuration Manager, all of which are accessed via the Admin drop-down menu (FIG. 5):
