RS-232 to RS-485 Serial Converter
RS-232 to RS-485 Serial ConverterThe RS-232 to RS-485 Converter provides a simple, low cost interface between a PC or laptop with an RS-232 serial port, and 2-wire RS-485 devices. Several features of this converter make it simple to use while providing maximum compatibility. RS-232 control lines are looped back to simplify hand-shake issues. Power for the converter is taken from the serial port lines - no external power supply is needed. In some cases, only transmit, receive, and ground are required. Power is also taken from DTR (data terminal ready) if provided. Switching between receive and transmit is automatically controlled. RTS (request to send) is not used to control transmit. A rugged design makes this device an ideal choice for field engineers and technicians who service RS-485 2-wire equipment in an industrial environment. Because the Microlink RS-485 converter is used on devices without a ground terminal, voltage suppression is used to clamp the common mode voltage to +/- 7 volts for increased protection.FeaturesAuto transmit control eliminates RTS requirementPower Up/Down glitch-free permits live insertion or removalPowered from RS-232 Com PortCommon mode range permits +/-7V ground differenceNot bus terminated - increases flexibilityRubber and stainless steel enclosure handles rough field useSuper low power design for extended portable computer battery lifeFCC and CE approved.
