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. 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 converter an ideal choice for field engineers and technicians who service RS-485 2-wire equipment in an industrial environment.
