21. Building the Emitter Soldering: The componets are all soldered in series in the following order. Pin 4 of the DB9 connector to the to the Anode (end without the stripe) on the Reverse Blocking Diode. Cathode of the Reverse Blocking Diode(the striped end) to either end of the Resistor. The other side of the resistor to the Anode (long lead) of the LED. Cathode of the LED (short lead) to Pin 5 of the DB9 connector.
