KNX Connector
The KNX connector on the rear panel is a 2-pin captive-wire connector that
provides communication between the NXB-KNX and the KNX control system
via 2-wire shielded twisted pair cabling (FIG. 4).
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 zero-
configuration 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):
Click on an option in this menu to access each of the configuration pages, as
described in the following sub-sections:
