Your case is not hard .
firstly, your device must have "rabbit" network connect confer, SCM writed a solid command ( program )for your device, example, a string,
As LV listens a IP port read its sending command, SCM read the command from LV sent, SCM would compare the receive string.
and take the action itself corresponding. and I suggest that LV is server, and your device is client. Please note SCM device's response time is not fast. LV should give much delay time for it.
