A compact, industrial-grade 2G/LTE gateway that enables a long-distance data transmission for industrial devices via the public cellular network (2G/LTE). Any serial RS422 enabled industrial device that needs optimal and recurring supervision from a distant central server can be connected to this LTE gateway with a minimal configuration setting.
With the ability to support multiple serial protocols such as Modbus RTU, ASCII or custom request/response, produce/consume, it functions as a multiprotocol gateway for various industrial applications. Additionally, this gateway can enable bi-directional communication, allowing remote control while monitoring. It also includes edge intelligence for increased operational effectiveness.
Our cloud platform provides a convenient way to view data from anywhere, integrating predefined widgets for applications like energy meter and flow meter reading. It supports remote device configuration, over-the-air firmware upgrades, and email/SMS notifications based on edge intelligence. User can download the reports in CSV, XLS, PDF..
By using our specially designed configurator tool, "PreciCon", it is possible to configure gateway’s serial settings, Modbus registers, event conditions & cloud settings. It also supports upgrading firmware and configuration of the device remotely over the air. This tool includes predefined configuration settings for devices from renowned manufacturers.
Our LTE gateways are designed and developed to withstand industrial environment and harsh electrical surge. Durable, robust IP40 rated ABS plastic enclosure can withstand the toughest conditions. With our in-depth knowledge in industrial use cases, we assure us to provide users with zero data loss in cloud dashboard even if there are glitches in cellular connectivity.

User Manual
Smart energy meters are most commonly in industrial automation applications where energy consumption, voltage/current levels and power factor information are acquired and processed in order to optimize their electricity consumption in real time. Though it provides instantaneous and totalized data in local display for manual observations, it is possible to acquire the data remotely round the clock via our Multiprotocol gateway.
RS422 Serial to LTE gateway works extensively with standard energy meters are available in market with various communication protocols such as Modbus RTU/ASCII or proprietary command/response. It enables rapid configurations, secure and reliable data transmission from the meter to our cloud server (PreciCloud), allowing real-time monitoring and analysis of energy consumption.

PLC’s are commonly used in industrial automation applications where low cost versions generally supports serial interface like RS485, RS232 or RS422. Among them, RS485 half-duplex serial communication will be commonly available with support for Modbus. Our RS485 serial IoT edge gateway can be used as a Modbus gateway for such PLCs where connections and commissioning are made easy with very few steps.
With our PreciCon configurator tool, user can simply select the desired PLCs from the list of renowned manufacturers. All the Modbus register settings are pre-configured where by just choosing the required data and upload interval will be more than sufficient for device configuration. Just write the configuration.

RS422 interface: Connects to industrial equipment, sensors, PLCs, or meters that use the RS422 serial protocol. LTE connectivity: Converts serial data to IP-based packets and sends them over a 4G/LTE network to cloud servers, applications, or remote PCs. Function: Acts as a bridge between serial devices and the internet, enabling: Remote monitoring, Control of devices, Data logging to cloud platforms
