AMX NXB-KNX Installation Manual

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.

Product Specifications
NXB-KNX Specifications
Front Panel • Status LED (green): Blinks once a second to indicate that
Components: the unit has powered up.
Any state other than blinking once a second indicates the
unit is either not powered, or has not completed boot up.
• KNX LED (green): Solid on indicates power is on and the
unit is connected to KNX bus.
• Output LED (red): Lights to indicate traffic from the
NXB-KNX to the KNX bus.
• Input LED (yellow): Lights to indicate traffic from the KNX
bus to the NXB-KNX.
Rear Panel • KNX 2-pin captive-wire connector:
Connectors:
• Ethernet Port - 10/100 Ethernet with PoE. LEDs show
communication activity, connection status, speeds, and
mode information:

speed is 100 Mbps and turns Off when the speed is
10 Mbps.
L/A (link/activity) - Green LED lights On when the Ethernet
cables are connected and terminated correctly, and blinks
when receiving Ethernet data packets.

NXB-KNX
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:

After completing the installation, consult the Using the Configuration Manager
(rear)
section of the NXB-KNX NetLinx Interface Operation/Reference Guide for
instructions on specifying IP and Security settings, via the NXB-KNX
WebConsole.

Straight-Through Wiring
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.
