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.
