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.
