These
are used mainly in hotel systems where 2 or more Sky digital
receivers are in operation. Their function is to restore up to 5
receivers back to the original channel settings in the event of a
power cut etc. There are 5 scart leads which connect to the vcr
port on each receiver and 5 female UHF leads which plug into the
RF out 2 port on each receiver. They work in a similar way to the
TV link only the signals are sent by the computerised module to
reset each channel. In the event of a power cut the unit will
automatically send out signals to each receiver to come out of
standby and go to the channel it was originally set.
