NXB-KNX KNX Communications Gateway

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.



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. 4). 

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