Metreau Entry Communicators
Ethernet 10/100 Base-T RJ-45 Wiring Configuration
The table below describes the pinouts, signals, and pairing for the Ethernet 10/100 Base-T connector and
cable. The Ethernet cable connection is illustrated in FIG. 7.
The Metreau Entry Communicators use CAT5/CAT6 wire via the Ethernet port for PoE power.
PoE (Power Over Ethernet)
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
MET-ECOM.
If the MET-ECOM is used with a PoE-capable Ethernet switch (such as the NXA-
ENET24PoE), then no PoE Injectors are required.
