Beschreibung

SUNIX STD1914, MedIO Interface Converter series, which provides a compact size and cost-effective solution for conversion between RS-232 and RS-422/485 interface. STD1914 extends RS-232 transmission distance up to 1.2 kilometer and increase networking capability by using a differential signal and multi-drop connections. Besides, low power consumption circuit design for user conveniently use external power adapter or USB port on the hosting device (e.g. PC). STD1914 offers greater flexibility in deploying commercial and industrial application.
