Data Sheet

RemoteCOM is a complete hardware and software solution for creating remote communication ports. Software part can be uploaded to any of the Redisage C20 - C25 Ethernet Converters. It provides a communcation between a LAN host and a device equipped with serial interfaces RS232/RS485. Dedicated app makes it easy and fast to configure and deploy. There is a possibility to create virtual COM ports with the Redisage Configurator to minimize number of cables.

Introduction

C20 - C22 are a family of products that are reliable converters based on the ESP32 Xtensa LX6 microcontroller, extending the capabilities of industrial devices.
C23 - C25 are a family of products that are reliable converters based on the STM32F4 microcontroller, extending the capabilities of industrial devices.

The addition of a network interface allows remote access and full control of communication via a computer.

The user performs the basic configuration of transmission parameters in the browser.

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

Applications

C20 - Ethernet Converter 2 x RS232

C21 - Ethernet Converter 1 x RS485

C22- Ethernet Converter 2 x RS232/RS485

In the C22 converter user should use only RS232 or only RS485 interface of one port as they occupy the same internal bus of the device.

C23 - Ethernet Converter 4 x RS232

C24 - Ethernet Converter 4 x RS485

C25 - Ethernet Converter 2 x RS232 & 2 x RS485

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.
