+91 8591900346 SN0001A User Guide 1 ABOUT THIS GUIDE This manual describes how to configure the S-node and S-node Modular Gateway. It contains specifications and setup information for S-node and S-node modular gateways. Follow this manual exactly for a complete setup. 2 INTRODUCTION 2.1 Product Overview (S-Node) S-node is a tiny, truly plug-and-play sensor node designed to enable predictive maintenance at a fingertip. S-node is able to measure 3D vibration, accostic emissions, gas emissions, RPM and IR thermal. S-node send data to the S-node modular gateway by using RF 2.4 GHz and Gateway send that data to the S-node cloud using MQTT protocol. A Highly scalable hardware architecture allows for plugging the sensors on a node as per the industrial requirement. Later on, machine learning algorithms will process data to estimate machine downtime and generate real-time notifications in the event of any unexpected situations, which will appear on the dashboard of the S-node.

+91 8591900346 SN0001A User Guide 3 Connecting The Hardware 3.1 S-node Modular Gateway Configuration S-node modular gateway is plug and play device. S-node modular gateway collects information from s-node and transmit the data to the cloud. S-node modular gateway is combination of two devices:

A. Gateway Motherboard B. Gateway RF Frontend A. Gateway Motherboard The Gateway motherboard has dual Gigabit Ethernet connectors and dual USB 3.0 ports, which makes it suitable for soft router applications that require less hardware. It have 4 GB RAM and 32 GB eMMC storage allow for quick boot-up times and a seamless overall experience. The S-node Modular gateway includes a range of I/O peripherals such as MIPI CSI, MIPI DSI, micro-HDMI to connect displays/cameras, a standard 9-pin USB 3.0 header for additional USB expansion, and an FPC connector all packaged in a compact form factor. It has a PC/ABS case with an Aluminum alloy on top, which has a large sink to cool down at extreme loads. This enclosure provides better protection and is ideal for industrial applications. The case has long rubber feet for better stability when placed on a flat surface and mounted in two different methods. One is to use the keyhole slot wall mount and hang it on the wall in two different orientations or use the three mounting holes and mount it onto a DIN rail. www.snode.io info@snode.io 6
