Здравствуйте. Простите, но не у кого спросить по ГОСТ18977:
1. Используется ли гальваническая развязка? явно в ГОСТ и РТМ не указано, но РТМ1495-75:
«2.2.4. … для устройств с оптоэлектронной или трансформаторной развязкой».

2. Как выдаются сигналы «Готовность» и «Запрос»? По двухпроводной линии (интерфейса по ГОСТ 18977-79), которая физически может быть использоваться и для передачи информации или как разовая команда?

3. Если не используется второй 1586ИН4АУ канал, достаточно ли подключить TESTA и TESTB к "GND"?
