On that same diagram - identify the corresponding 5 volt pin. E.g. if your RxD went to R2IN (pin 32) then the 5volt pin will be the R2OUT (pin 22). | On that same diagram - identify the corresponding 5 volt pin.

For the +5v (VCC) we do a bit of a cheat - we wire it to one of the 'free' pins on the DB9 - so we can more easily solder a wire to it. | For the +5v (VCC) we do a bit of a cheat - we wire it to one of the 'free' pins on the DB9 - so we can more easily solder a wire to it. This is the diagonal on the diagram - in our case we're using the old ring-indicator pin for this. | ||
