Additional information

SUNIX STD1918 to zaawansowany media konwerter szeregowego interfejsu RS-232 na RS-422/485 i odwrotnie. RS-232 to prosty, a zarazem popularny interfejs w środowisku przemysłowym jak i rynku programów użytkowych. Wadą standardu RS-232 jest ograniczenie odległości transmisji do 15metrów, jednakże konwerter SUNIX dostarcza idealne rozwiązanie dla rozciągnięcia owej odległości jednocześnie rozszerzając zdolności urządzenia. Użytkownicy mogą wykorzystać urządzenie RS-232 w celu podłączenia się do przemysłowych interfejsów RS-422/485 i w ten sposób podciągnąć transmisję do odległości nawet 1.2 kilometra wykorzystując zróżnicowanie sygnału i połączenia "multi-drop".
