### 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. ### {{@175#bkmrk-specification}} {{@175#bkmrk-redisage-pn-g01-g02-}} ### Variants #### G01 - Ethernet Modbus Gateway 2 x RS232
#### G02 - Ethernet Modbus Gateway 1 x RS485
#### G03 - Ethernet Modbus Gateway 2 x RS232/RS485

In the G03 gateway user should use only RS232 or only RS485 interface of one port as they occupy the same internal bus of the device.

#### G14 - Ethernet Modbus Gateway 4 x RS232
#### G15 - Ethernet Modbus Gateway 2 x RS232 & 2 x RS485
#### G16 - Ethernet Modbus Gateway 4 x RS485

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 [![38965053-10b3-4e51-be9b-957b01b9938c.png](https://doc.redisage.com/uploads/images/gallery/2024-03/scaled-1680-/38965053-10b3-4e51-be9b-957b01b9938c.png)](https://doc.redisage.com/uploads/images/gallery/2024-03/38965053-10b3-4e51-be9b-957b01b9938c.png) Ethernet Modbus gateways G14 - G16 have 5 LED indicators: - PW LED Blue - Power - ER LED Yellow - Error - ETH LED Green - Network activity - COM LED Green - RS232/RS485 activity - CN LED Yellow - Console mode - SR LED Red - Service mode [![fd2973ab-76ee-4878-b4ee-4b7626f6cc94.png](https://doc.redisage.com/uploads/images/gallery/2024-03/scaled-1680-/fd2973ab-76ee-4878-b4ee-4b7626f6cc94.png)](https://doc.redisage.com/uploads/images/gallery/2024-03/fd2973ab-76ee-4878-b4ee-4b7626f6cc94.png) #### 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. [![image.png](https://doc.redisage.com/uploads/images/gallery/2025-03/scaled-1680-/kzHimage.png)](https://doc.redisage.com/uploads/images/gallery/2025-03/kzHimage.png) After successful login, the “Status” page will show the current status of the ports. [![4f6ed827-ab6f-4372-8bef-95d723d573c8.png](https://doc.redisage.com/uploads/images/gallery/2024-03/scaled-1680-/4f6ed827-ab6f-4372-8bef-95d723d573c8.png)](https://doc.redisage.com/uploads/images/gallery/2024-03/4f6ed827-ab6f-4372-8bef-95d723d573c8.png) To change the user name and password click on the user icon and select “Edit user”. Ports configuration is available on the “Ports” page. [![7b227942-77c0-4f47-84f7-1bddcca0f5be.png](https://doc.redisage.com/uploads/images/gallery/2024-03/scaled-1680-/7b227942-77c0-4f47-84f7-1bddcca0f5be.png)](https://doc.redisage.com/uploads/images/gallery/2024-03/7b227942-77c0-4f47-84f7-1bddcca0f5be.png) {{@175#bkmrk-item-description-int}}

Changing the port’s service closes all sockets connected to the ports.

Network settings can be changed on the “Network” page.
