Summary of Customer solution: Trouble-free RS232, RS422, RS485 to USB conversion
The article highlights the FT232R integrated circuit and introduces USB-to-serial converters developed by ComErgon, s.r.o. These devices facilitate communication between modern computers lacking serial ports and legacy equipment using RS232, RS422, or RS485 interfaces. The text emphasizes that RS422 and RS485 models include 1kV galvanic isolation to prevent damage from overvoltage on long lines, while RS232 versions are available with or without isolation.
Parts used in USB to Serial Converters:
- FT232R Integrated Circuit
- USB to RS232 Converter
- USB to RS422 Converter
- USB to RS485 Converter
- Galvanic Isolation Component
- RS422/RS485 Repeaters
- Serial to Ethernet Interface Modules
Integrated circuit FT232R is becoming legendary and we bring you another example of FTDI USB chips usage.
In praxis we often face a requirement to communicate with devices, which have serial ports RS232, RS422 and RS485. As many devices – mainly notebooks, already usually don´t have these ports, it is necessary to use a converter to convert serial port to USB.
Company ComErgon, s.r.o. is long-term dedicated to development and production of such converters. ComErgon has in its offer models for RS232, RS422 a RS485 interfaces. USB to RS422 and RS485 converters are produced with a 1kV galvanic isolation, as lines on the RS422 and RS485 side can be lead even on long distances and an eventual overvoltage could be able to damage end devices. Version RS232-USB is available with galvanic isolation but also without isolation.
More detailed information and technical specification of these converters can be found at website of company ComErgon.
Company ComErgon focuses on development and production of converters for RS232, RS422, RS485, RS422/RS485 repeaters, serial to Ethernet interface modules, GPRS, Fiber Optic, 433MHz, current loop and other.

- Why is a converter necessary for modern notebooks?
Many modern notebooks do not have serial ports like RS232, RS422, or RS485, requiring a converter to communicate with such devices. - Does the RS422 converter feature galvanic isolation?
Yes, USB to RS422 converters are produced with 1kV galvanic isolation to protect end devices from potential overvoltage. - Are RS485 converters available with isolation?
Yes, USB to RS485 converters are produced with 1kV galvanic isolation because these lines can be run over long distances. - Is the RS232 version always isolated?
No, the RS232-USB version is available both with and without galvanic isolation. - What other products does ComErgon produce besides USB converters?
ComErgon also produces RS422/RS485 repeaters, serial to Ethernet modules, GPRS, Fiber Optic, 433MHz, and current loop interfaces. - Which company develops these specific converters?
Company ComErgon, s.r.o. is dedicated to the development and production of these converters.
