Port-poweredRS232 to RS422 Converter

Model:TLC422Introduction:TLC422 is the interface converter between RS-232 and RS-422. It is powered from serial port (such as COM port of computer ), no outside power needed. Small size, long transmission distance, high rate, stable performance. It applys DB9 common serial port. It is used widely in the field of electricity, industrial automatic control, IC card billing system. It is a high quality low price data interface conversion product.
