STD1918H

SUNIX STD-1918H 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.

Features:

Industrial grade design for stability and reliability. 12V DC Jack & External power 12~48V DC terminal block with reverse polarity protection. Embedded ESD surge protection built-in. Optical isolation provides protection against damage from static electrical charge. Power surge protection provides protection against surge damage from high energy spike. Auto Tune feature provides automatic setup of communication protocol. RS-422/485 Auto Detect and Switch technology enable serial device plug-n-play without jumper or switch setting. RS-485 AHDC/CS technology allows accurate switching of the transmitter on and off for precise timing of the data transmission. RS-232 to RS-422/485 converter with RTS+/- CTS+/- support. RS-422/485 Handshaking Communication provides hardware flow control for best prevention of data error or data lost. Plug-in screw terminal block for easy RS-422/485 wiring. Detachable wall and DIN-rail mounting kit design. Plug-n-play & compact size designed.
