### Introduction

Devices are based on G01 - G03 gateways (**ESP32 Xtensa LX6 microcontroller**) and G14 - G16 gateways (**STM32F4 microcontroller**) depending on needed ports and interfaces.

Dedicated EMC integrated circuits guarantee improved connection quality by limiting the impact of interference typical for an industrial environment.

### Getting started  


#### Power supply  


Ethernet Modbus gateways G01 - G03 and G14 - G16 have wide voltage power input (12 - 30 VDC). The power consumption is less than 1 W.

#### LED indicators  


Ethernet Modbus gateways G01 - G03 have 3 LED indicators:

- PW LED Blue - Power
- ETH LED Green - Network activity
- ST LED Orange - USB-UART Serial console mode
