В электронике очень плохо разбираюсь , пожалуйста , подскажите .
Дали фрагмент схемы Геки540 , я его перерисовал для низкого
разрешающего уровня ( правильно ? ) . Плату распаял , теперь
возникли сомнения . Точки 3 и 4 втыкаются в разрыв кабеля ЛПТ -
1 пин . Сигнал у меня идет на плату PLC4xx от Пурелогика .
В ЛПТ уровни сигнала 5 вольт , а питающее на плате подкачки 12 вольт .
Не сожгу я порт компьютера и вход PLC4xx ? И будет PLC4xx правильно
" понимать " входной сигнал ENABLE другого уровня ?
Если об этом говорилось , ткните , плиз .
