Реализация rs232 и rs485

Сообщение polinom » 15 окт 2013, 18:37

Добрый день!

Заинтересовал вирт2риал, хочу попробовать на его базе реализовать для домашнего пользования опрос водосчетчиков и электросчетчиков.
все счетчики имеют протокол modbus RTU, но водосчетчики имеют интерфейс rs485, а вот счетчик электричества rs232.

Естественно возник вопрос есть ли уже готовые решения какие-то, реализующие на вирт2риал оба эти интерфейса?

Если нет, то куда копать и что бы изучить для начала т.к. в схемотехнике я чайник полный?

PS: забыл упомянуть, что преобразователи USB-rs232/rs485 не предлагать, хочется получить отдельную плату, чтоб было по "пацански" :mrgreen:

Так uart на v2r поддерживает RS485?
Задумался над покупкой динамикселов а они как раз по 485 управляются.
