Introduction
Devices are based on G11 - G13 gateways (ESP32 Xtensa LX6 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.

Variants
G11 - Ethernet + Wi-Fi Modbus Gateway 2 x RS232
G12 - Ethernet + Wi-Fi Modbus Gateway 1 x RS485
G03 - Ethernet Modbus Gateway 2 x RS232/RS485
In the G13 gateway user should use only RS232 or only RS485 interface of one port as they occupy the same internal bus of the device.
Frame ground FG
Electronic circuits are constantly prone to electrostatic discharge ESD. Redisage Electronics modules feature a design for the frame ground terminal block FG. The frame ground provides a path for bypassing ESD, which provides enhanced static protection ESD abilities and ensures the module is more reliable. Connecting FG terminal block to the earth ground will bypass the ESD disturbances outside the device so will provide a better level of protection against ESD.
Frame Ground FG connection reference drawing is provided below.
If earth ground is not available FG can be left floating or it can be connected with the power supply GND.
