### 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

#### Configuration by the Web Page

Default configuration of the Ethernet Modbus gateways:

- IP address: **192.168.100.100**
- Subnet mask: **255.255.255.0**
- Gateway: **192.168.100.1**
- DNS 1: **192.168.100.1**
- DNS 2: **8.8.8.8**

Default login details:

- User name: **admin**
- Password: **admin123**

To access the web page, open the web browser, type the IP address in the address bar and log in using the default user name and password. The device and a PC must be connected to the same Local Area Network.

{{@175#bkmrk-item-description-fir}}

#### Configuration by the Serial Console  


The device can be reconfigured via a serial console. In case of the G01 - G03 Modbus gateways, an additional USB/UART converter is needed.
