Converter RS232 to RS485


Product Description

SUNIX STD-1914SA advanced media converter provides serial interface exchange between RS-232 to RS-422/485 and vice-versa. RS-232 hardware is a popular used and easy design interface in today's industrial environment and commercial application. However the drawback of RS-232 is the point to point characteristic and a distance limitation of 15 meters, SUNIX converter provides an ideal solution for extending RS-232 transmission distance and increasing networking capability. Users can use RS-232 devices to connect to an industrial RS-422 or RS-485 network and increase transmit data up to 1.2 kilometer by using a differential signal and multi-drop connections.
