* DEFINED_SCALE - 4 bytes user defined max output scale value.
* CONTROL_HIGH - 4 bytes control high set point value see section 4 for its data
representation.
* CONTROL_LOW - 4 bytes control low set point value see section 4 for its data
representation.
* ALARM_STATUS - 1 byte alarm state settings, see section 3 for details.
* Reply just used for confirm uploading successfully, DATA1 and DATA2 no real meanings.
08. 930 unit configure settings download command, total 25 bytes stream.
Command: BASE, PARAMETERS_DOWNLOAD, NETWORK_ID, EMPTY, CHECKSUM
Reply: SENSOR, PARAMETERS_DOWNLOAD, NETWORK_ID, ALARM1, ALARM2,
DEFINED_SCALE, CONTROL_HIGH, CONTROL_LOW, ALARM_STATUS, CHECKSUM
* ALARM1 - 4 bytes alarm 1 set point value, see section 4 for its data representation
* ALARM2 - 4 bytes alarm 2 set point value, see section 4 for its data representation
* DEFINED_SCALE - 4 bytes user defined max output current output value

09. Specific 930 base unit version number request command and reply. PC or other devices can
request the base unit version information.
Command: BASE, BASE_VERSION, NETWORK_ID, EMPTY, CHECKSUM
Reply: SENSOR, BASE_VERSION, NETWORK_ID, VERSION_NUM, SENSOR_COUNT,
RESERVED, RESERVED, RESERVED, RESERVED, RESERVED, RESERVED,
RESERVED, RESERVED, RESERVED, CHECKSUM
* VERSION_NUM - 1 byte, the version number of the 930 unit
* SENSOR_COUNT - 1 byte, actually used to specify its 930
if it's 0x01, that is 930 no temperature and humidity sensor connected,
if it's 0x03, that is 930 there is a temperature and humidity sensor connected.
10. Temperature and relative humidity data request command. The command asks for the
temperature and humidity data that a specific 930 unit currently holds. The 930 unit responds
with two values respectively.
Command: BASE, TEMP_RH_DATA, NETWORK_ID, EMPTY, CHECKSUM
Reply: SENSOR, TEMP_RH_DATA, NETWORK_ID, TEMP, RH, RESERVED, STATUS1,
STATUS2, CHECKSUM
* TEMP - 4 bytes IEEE754 floating point data, measured temperature value of 930 unit,
* RH - 4 bytes IEEE754 floating point data, measured relative humidity value of 930 unit
* For 930 the command will be no reply at all.
