Yes, but I would recommend to buy also a powerbar to control your devices...
Perhaps the ProfiLux Plus II ProfiSet would be an option? Here, the powerbar and the RS232-cable are already included.

Yes, definitely! The use of an ordinary PC-cable can even lead to malfunction and destruction of the devices. Sorry if I confused you by saying at the GHL cable there is an extra pin. It is not additonal, but it is a very special one (of these 9) that routes special ProfiLux-signals. A common cable can't identify and route these signals.
