Quatech SS-CVT-XXX User Manual
KEY FEATURES
RS-232 to RS-422/485
Isolated, RS-232 to RS-422/485
Auto data flow control for RS-422/485
Surge protection for RS-422/485
Wrong polarity voltage input protection
Up to 110kbps under 1200m/4000ft
Standard 15kv ESD protection and surge suppression
SS-CVT-500I: Auto detect/switching between RS-485 and RS-422
SS-CVT-500I: Photo coupling and DC to DC isolation
Quatech's Serial Converters allows RS-232 line
signal bi-directionally convert to RS-422 or RS485 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
provides photo couple and DC to DC isolation.
