Ethernet Gateway

Connect Your IoT Sensor Network to the Internet

Monnit ALTA® Ethernet Gateway and ALTA XL® Ethernet Gateway allow ALTA Wireless Sensors to communicate with the iMonnit™ Wireless Sensor Monitoring and Notification System without the need for a PC. Simply provide power and plug the ALTA Ethernet Gateway or ALTA XL Ethernet Gateway into an open Ethernet port with an Internet connection. Then it will automatically connect with our online servers, providing the perfect solution for commercial locations with an Internet connection.

The ALTA XL Ethernet Gateway features a powerful wireless transceiver with up to 1 Watt transmission strength and an amplified receiver. The ALTA XL Ethernet Gateway can send and receive data communications with ALTA Sensors 2,000+ feet through 18+ walls in commercial building environments.

Gateway Features

  • Updated Modbus TCP-IP and SNMP to support new sensor profiles
  • Internet MIB (management information base) is implemented on the gateway for industry tools to auto-discover the gateway and understand its features
  • Enhanced SNMP walk to only show data for valid OIDs (sensor data that exists in the system)
  • SNMP Interface: in addition to integers, the gateway has additional OIDs to present the same data in HEX and string (human-readable) format

*If you plan to use an alternative interface to the sensors other than (such as Modbus TCP, SNMP, the direct push of data from gateway to on-premises, or third-party server), the purchase of an unlock code will allow free roaming of the data from the hardware.
