Smart Sensor Pairing
Pairing a Layer N Smart Sensor to your Layer N Gateway is made
easy with one-button pairing. Simply press the pairing button on
your gateway and press the pairing button on your Smart Sensor
to connect the two. Your Smart Sensor will now be visible on your
Layer N Cloud or OEG web interface.
USB 2.0 Connectors

The USB 2.0 connector is used to connect Layer N
Smart Probes with a Layer N IF-001 Smart Interface
Cable directly to your gateway.
Serial Data and Alarm Connector

Alarm Relay Wiring
The 5-pin screw terminal can be used to connect a peripheral alarm
relay that will be triggered if the gateway loses network connection
to the Layer N Cloud or OEG.
Note:
This alarm will not detect a cabling or wiring issue. The alarm
will sound if the Gateway cannot reach the Layer N Cloud or
OEG network.
RJ45 Port

An RJ45 port is provided for local-network and Internet access, can be used for ModBus TCP devices, and some models
offer a Power over Ethernet feature.
