Write Commands
All write commands are dispatched with specific number of data bytes which are written to
specified parameters after parsing process. In case of a single sensor the parameters of
disconnected sensor are also included in the request data although those can be set at 0. The
response of a write command is the same as the request. The details are provided in the
Table A - 4.
