ALTA Ethernet Gateway 4

EGW4-Gateway.jpg

Monnit’s Ethernet Gateway allows your Monnit Wireless Sensors to communicate with the iMonnit™ Online Wireless Sensor Monitoring and Notification System without the need for a PC. Simply provide power and plug the gateway into an
open Ethernet network port with an internet connection.
It will then automatically connect with our online servers, providing the perfect solution for commercial locations where there is an active internet connection.
The Power-Over-Ethernet option features modified gateway hardware allowing it to be powered through the Ethernet port. (Does not include PoE Power Injector.)
Interfaces supported: Modbus, TCP/IP, and SNMP.
