The output LED 2 will switch on and you will hear the relay contact switch to a closed state.

Now repeat the set/reset procedure of the last two examples. You will receive messages with a reverse behaviour of the output LED and relay contact. E.g. after a ‘SET’ command, the LED goes off and the relay contact switches to the open state and opposite.
