Functional Overview
Low Power Intel® Celeron®

N3350 1.1 GHz dual-core processor with 8GB system memory delivering high performance and low power consumption.

Simple to Deploy and Provision

Wire up the devices to be monitored, add an Outbound Ethernet connection (optionally Wifi or LTE) and apply power. All setup can be performed within the Mango Cloud Platform remotely.

Native Connectivity

Native Connectivity to BACnet/IP, BACnetMS/TP, MQTT, Modbus RTU/TCP, Serial and over plenty of protocols to gather data.

Mango Cloud

The Mango Cloud platform consolidates, tags, and formats all the harvested data into a single source API allowing remote analytics and visualization platforms to access the entire data collection.

Global Cellular and Integral GPS

Global Cellular and Integral GPS allowing for data backhaul via worldwide cellular networks when ethernet is not a possibility.

IP40 Rating

IP40 Rating with a rugged wide-temperature operating range, and fan-less design making it perfect for housing directly in sealed equipment or electrical cabinets in areas without climate control.
