Преобразователь USB-TTL PL2303 — это небольшой USB модуль, который эмулирует последовательный интерфейс UART (RS-232). То есть подключая этот преобразователь в USB порт компьютера, виртуально создается COM порт.
В октябре года 2012 Фирма Prolific прекратили производство и поддержку микросхем UART PL2303X (Chip Rev A) и PL2303X HX (Chip Rev A), а начала производить микросхем PL2303TA. Но и сейчас, можно купить преобразователь на микросхеме PL2303HX (с поддельным чипом). При использовании ОС Windows 8 или Windows 10, система автоматически устанавливает последнюю версию драйверов, в которой нет поддержки этих чипов, а в диспетчере устройств будет показан желтый знак с кодом ошибки 10 (Запуск этого устройства невозможен. (Код 10) или This device cannot start. (Code 10)).
Чтобы преобразователь работал в ОС Windows 8 и Windows 10 необходимо установить старый драйвер, например PL2303_Prolific_DriverInstaller_1025 (3.3.3.114 (14/01/2009)) или PL2303-Prolific-DriverInstaller-v1.5.0.zip (3.4.25.218 [07.10.2011]).
Удаление драйвера для PL2303HX
Для начала отключите преобразователь PL2302HX от компьютера и, если на компьютере установили последнюю версию драйвера, удалите его. Перейдите в Панель управления Start->Control pane->Programs and Feaetures.
Проверьте, установлен ли PL-2303 USB-to-Serial и нажмите Uninstall, чтобы удалить драйвер.
Установка драйвера для PL2303
Теперь надо установить старый драйвер. Скачайте архив PL2303_Prolific_DriverInstaller_1025.7z, распакуйте из него файл PL2303_Prolific_DriverInstaller_1025.exe. Кликнете мышкой два раза по нему и установите драйвер.
Подключите преобразователь к компьютеру и перейдите в Диспетчер устройств Start->Control pane->Device Manager. Тут мы видим, что наше устройство с желтым знаком и показывает ошибку: Запуск этого устройства невозможен. (Код 10) или This device cannot start. (Code 10).
Для отката драйвера, нажмите правой кнопки мыши на Prolific USB-to-Serial Comm Port и выберите Обновить драйвер/Update device driver.
Нажмите Выполнить поиск драйверов на этом компьютере/Browse my computer for driver software.
Так как уже установлен старый драйвер, просто нажмите на опцию Выбрать драйвер из списка уже установленных драйверов/Let me pick from a list of available drivers on my computer.
Из списка установленных драйверов, выберите драйвер Prolific USB-to-Serial Comm Port Version 3.3.3.114(14-Jan-09) и нажмите кнопку Далее/Next для продолжения.
Windows будут затем установить старый драйвер обратно в систему.
Нажмите кнопку Закрыть/Close. Если после установки выдаёт ошибку Запуск этого устройства невозможен. (Код 10)/This device cannot start. (Code 10), нужно отключить преобразователь от компьютера и вставить обратно.
Если драйвер установлен правильно, вы увидите ваше устройство Prolific USB-to-Serial Comm Port без жёлтого знака.
Щелкните два раза по устройству, чтобы подтвердить версию драйвера.
Можете перемычкой соединить Tx и Rx и в Terminal 1.9b отправить сообщение.
