Please note: SCART sockets

Many devices such as SAT receivers, video recorders or DVD players output a switching voltage through the SCART socket as soon as they are switched on.

On a standard SCART socket, PIN 8 outputs the positive voltage (+) and PIN 4 or 14 is the earth (-).

The principle of Master/Slave socket outlets

With this type of socket outlets, the control device (the TV in the above example) is plugged into the master socket while all other devices are connected through the slave sockets. As long as the master device is not switched on, all slave sockets remain switched off. Once the master device is switched on, all the slave sockets (the plug-in power supply in the above example) are switched on at the same time.

In this way, you can “upgrade” any type of device to give it a switching- voltage output.
