On some commands, one or all parameters are ignored.

For UDP, command type and parameters need to be in the same datagram.

Responses to valid commands are always five bytes long, consisting of the returned
command byte and as parameters in the current or updated values. In case of an
invalid command, only one byte with value 0FFh is returned.

when the unit is powered down or rebooted.
