Hello Jorge,
It is better to use the OUT 0 as Mike suggested because if your internet connection fails then the connection will be lost and the OUT 0 line will also go off. If OUT 0 controls a relay for the transceiver then that will also be turned off if your internet connection fails.
With the webswitch, the relays stay in the last set condition and do not turn off if the connection is lost, thus in this case your transceiver will stay on of the internet connection is lost.
With the IC 7000, connect the power and then turn it on in the normal way. From then on every time the power is connected the IC 7000 will come on, do not turn off the 7000 via the front switch.
My remote IC 7000 has been working in this configuration ( OUT 0 and a high current relay) for over a year now and it is very reliable, the biggest hazards to the remote operation are my fingers.
