Normal Socket– Plug peripheral computer or TV/AV appliances in here that you want to remain connected to mains power at all times.
In an AV/TV environment this can apply to Pay TV units, DVD and/or Video Recorders on which you pre-program recordings ahead of time, TiVo on which you pre-program the recording at specific times of future TV programs, or any other appliance relying on a continuous timer or clock.
NOTE: Some projectors have a step down process when they are turned off which allows the projectors lights to cool gradually after use. These appliances should be plugged into the normal socket.
In a Computing environment some people may want their computer to remain connected to the internet even when they are not using their computer and may plug their modem into the Normal socket.
Master Socket – For an AV/TV Powerboard, plug your TV into the Master socket. When your TV is in Low Power Mode the powerboard will use this as a signal to disconnect mains power from the TV Master and all the Slave appliances.
For a Computer Powerboard, plug your Computer in here. When the Computer is in a low power mode (OFF, or SLEEP, or HIBERNATE are common examples) the device will disconnect mains power from the Slave appliances.
Note: a computer plugged into the Master socket is never disconnected from mains power so it can continue to function as it normally would in low power modes (like SLEEP or HIBERNATE). There is no possibility of lost work in open work files as a result of using the device.
Slaves Socket –Plug other peripheral computer or TV/AV appliances in here.
In an AV/TV environment, when the TV Master is turned into a low power mode (OFF or STANDBY are often common examples) the device will disconnect mains power to these Slave appliances. (Usually this is your DVD player, games console, set top box, home entertainment systems, speakers, stereo surround sound etc.).
In a computer environment, when the Computer Master is in a low power mode (OFF, SLEEP or HIBERNATE are often common examples) the device will disconnect mains power to these Slave appliances. (Usually this is your printer, monitor, speakers, external hard drives, etc.)
