Quatech's SS-CVT-500I serial converter allows RS-232 line signal bi-directionally convert to RS-422 or RS-485 standard. Featuring data format DIP switching and baud rate auto switching (from 110bps to 115.2Kbps) users only need to plug the unit and go without software or hardware complicated setting. The RS-485 control is completely transparent to the user and software written for Half-Duplex RS-232 works without any modification. SS-CVT-500I additionally provides photo couple and DC to DC isolation for both signal and power lines.
