(some are optional) note that the user password is case sensitive but the commands are not case sensitive and will be converted into upper case before the unit handles them. this means that any user command responses, which echo the original command will do so in upper case. all commands are sent as text messages from a mobile phone. com no nc relay connections when transmitter not operating com no nc relay connections when transmitter operating ch1 ch2
