For a replacement product, see the RSLink2.

The RSLink converts between typical microcontroller 0-5 volt UART signals and the true RS-232 signals required to communicate with a standard PC COM port.  On the microcontroller side it connects to ground, 5V power, and the 0-5 volt receive and transmit lines.  The RS-232 interface is via a female DB-9 connector.  It can be connected to a standard PC COM port with a straight thru extension cable.
