IMPORTANT SAFETY INSTRUCTIONS

1. READ these instructions.

2. KEEP these instructions.

3. HEED all warnings.

4. FOLLOW all instructions.

5. DO NOT use this apparatus near water.

6. CLEAN ONLY with dry cloth.

7. DO NOT block any ventilation openings. Install in accordance with the manufacturer's instructions.

8. DO NOT install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that
produce heat.

9. DO NOT defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the
other. A grounding type plug has two blades and a third grounding prong. The wider blade or the third prong are provided for your
safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10. PROTECT the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where
they exit from the apparatus.

11. ONLY USE attachments/accessories specified by the manufacturer.

12. USE ONLY with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is
used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. UNPLUG this apparatus during lightning storms or when unused for long periods of time.

14. REFER all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as
power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been dropped.

15. DO NOT expose this apparatus to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on
the apparatus.

16. To completely disconnect this apparatus from the AC Mains, disconnect the power supply cord plug from the AC receptacle.

17. Where th e mains plu g or an applian ce coupler is u sed as the di sconn ect device, the dis connect de vice shall rem ain readily o perable.

18. DO NOT overload wall outlets or extension cords beyond their rated capacity as this can cause electric shock or fire.

The exclamation point, within an equilateral triangle, is intended to alert the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the product.

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous
voltage" within the product's enclosure that may be of suff icient magnitude to constitute a risk of electrical shock to persons.

ESD Warning: The icon to the left indicates text regarding potential danger associated with the discharge of static electricity from an outside
source (such as human hands) into an integrated circuit, often resulting in damage to the circuit.

WARNING: To reduce the risk of f ire or electrical shock, do not expose this apparatus to rain or moisture.

WARNING: No naked flame sources - such as lighted candles - should be placed on the product.

WARNING: Equipment shall be connected to a MAINS socket outlet with a protective earthing connection.

WARNING: To reduce the risk of electric shock, grounding of the center pin of this plug must be maintained.

Wiring and Connections

Installation

CAUTION:

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:

FIG. 2

After you have completed the installation, consult the Configuration section on page 8.

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

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 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.

KNX Connector

The KNX connector on the rear panel is a 2-pin captive-wire connector (optically isolated) that provides communication between
the NXB-KNX and the KNX control system via 2-wire shielded twisted pair cabling (FIG. 3).

Overview

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 NXB-KNX device. The web console consists of a series of web pages that are collectively called the "NXB-KNX
Configuration Manager" (FIG. 4).

Configuration

NXB-KNX Configuration Manager - IP Settings Page (initial view)

FIG. 4

The NXB-KNX is set to DHCP by default.

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 NetLinx
Studio v3.0 (or higher), or a similar zero-configuration client.

Zero-configuration (or Zero-Config) 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.

NetLinx Studio (featuring Zero-Config functionality)

NetLinx Studio (v3.0 or higher) features a "Zero-Config" tab in the Workspace Window. This tab provides Zero-Config networking
functionality within NetLinx Studio (FIG. 5).

FIG. 5 Workspace Bar - Zero-Config tab

Refer to the NetLinx Studio online help for details on using Zero-Config.

Accessing the NXB-KNX WebConsole via Zero-Conf ig

Assuming that the NXB-KNX resides on the same LAN as the PC running NetLinx Studio, and the NetLinx Master to which the NXB­KNX is connected, you can access the NXB-KNX via the Zero-Config feature in Netlinx Studio, as described below:

1. In NetLinx Studio (version 3.0 or higher), right-click inside the Zero-Conf ig tab of the Workspace Bar to access the Zero­Config context menu (FIG. 6).

FIG. 6

NetLinx Studio - Zero-Config context menu

2. Select Refresh List to generate an initial listing of all Zero-Config devices detected (FIG. 7).

3. Click the plus symbol (+) to expand any device in the Zero-Config list. The device’s current IP Address is listed below the
devi ce name (FIG. 7):

FIG. 7 Workspace Bar - Zero-Config tab

4. You can access any device in the Zero-Config list simply by double-clicking on it's entry. The sele cted device's WebCon sole
(HTML) is displayed in a NetLinx Studio window.

5. The unit’s IP Address can be edited IP Settings page (see the IP Settings on page 12).

Accessing the WebConsole via Web Browser

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 (FIG. 4).

Admin Menu

There are several configuration pages included in the Configuration Manager, all of which are accessed via the Admin drop-down
menu (FIG. 8):

FIG. 8 NXB-KNX Configuration Manager -Admin menu

Click on an option in this menu to access each of the configuration pages, as described in the following
sub-sections:

NOTE: If you see the additional entries: Application Upgrade and Firmware Upgrade in the Admin menu, it is an indication that your
NXB-KNX is currently using an older version of the device Application and Firmware. Refer to the One-Time Upgrade of the NXB-KNX
to a Native NetLinx Device on page 40 for instructions on upgrading your NXB-KNX to the latest NetLinx Firmware. Once the unit has
been upgraded to the current version of NetLinx Firmware, the Admin Menu will appear as it is shown in FIG. 8.
