 REV: A
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 MET-ECOM-DNS-B uses 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.
Note: The MET-ECOM-DNS-B 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 MET-ECOM-DNS-B.
If the MET-ECOM-DNS-B is used with a PoE-capable Ethernet switch (such as the 
NXA-ENET24PoE), then no PoE Injectors are required.
Input/Output (I/O) Port: Connections and Wiring
The I/O port responds to either switch closures, voltage level (high/low) changes, or it can 
be used for logic-level outputs. A contact closure between the GND and an I/O port is 
detected as a Push. 
When used for voltage inputs, the I/O port detects a low signal (0 - 1.5 VDC) as a 
Push, and a high signal (3.5 - 5 VDC) as a Release (this IO port uses 5V logic but can 
handle up to 12V without harm).
When used for outputs, the I/O port acts as a switch to GND and is rated for 200 mA 
@ 5 VDC. This device can use up to 2 I/O ports (see table below).
The PWR pin provides +5 VDC @ 200 mA.
The GND connector is a common ground and is shared by all I/O ports. A common 
ground is shared with I/O ports 1 - 4 (see table below).  
Connecting The Device via I/O
When connecting the I/O port, the GND on the MET-ECOM-DNS-B must be connected to 
the ground of the I/O device, e.g., a master or any third party I/O device.
Relay Port: Connections and Wiring
You can connect up to 2 independent external relay devices to the Relay connectors on the 
Metreau Entry Communicators. 
Connectors labeled A are for common; B are for output.
Each relay is isolated and normally open. 
Use A for common and B for output. Each relay is isolated and normally open.
I/O and Relay Connectors - Pinout Configurations
FIG. 3 shows the pin configuration on the I/O and Relay ports. 
Note: Do not use the relays on this unit for "secure" applications such as door and gate 
releases. For security reasons, an external relay box put in a secure location will work 
better for these devices.
Ferrite Installation (Required)
The MET-ECOM-DNS-B comes with a Cat5 Suppression Ferrite that must be clipped 
around the Ethernet cable, inside the back box (no tools required). 
1.
Release the latch to open the plastic enclosure.
2.
Insert the Cat5 cable and close the enclosure.
Note: When positioning the Ferrite clip inside the back box, place the bottom of the clip flat 
against the back inside surface of the back box, to allow sufficient room for the Metreau 
unit. See the Operation/Reference Guide for details.
Mounting Specifications
FIG. 5 shows the recommended cutout for the MET-ECOM-DNS-B Rough-In Box. Use 
these dimensions for wall surface installations using expansion clips.
Note: Refer to the Metreau Entry Communicators Operation/Reference Guide for additional 
installation details and drawings.
Positioning the Camera
Metreau Entry Communicators feature a Camera Viewing Angle Adjustment slider on the 
rear panel of the unit that allows you to adjust the viewing angle horizontally from -15° to 
15° (see FIG. 2).
The Camera Viewing Angle Adjustment slider is intended to be used at the time of 
installation. It is not intended to be used for regular periodic adjustments. Once a final 
installation location has been established, use the Camera Viewing Angle Adjustment slider 
to set the desired camera angle, then finalize the installation.
Installing the MET-ECOM-DNS-B 
To install the MET-ECOM-DNS-B in to the Rough-In Box:
1.
Insert the Metreau unit into the Rough-In Box at an angle, sliding the bottom in first 
(FIG. 6). 
2.
Slide the top of the Metreau unit into the Rough-In Box until the Tab on top of the 
Metreau unit reaches the edge of the Rough-In Box.
3.
Depress the Tab to allow it to slide into the Rough-In Box, and slide the top of the 
Metreau unit completely in, allowing the Tab to engage in the notch in the Rough-In 
Box.
4.
Push the bottom of the Metreau unit in, to fully seat the unit within the Rough-In Box.
