Time
2
This 2 byte encoded 6 bit binary encoded (see below) number is
a number of minutes into the day. It tells when the most recent
(first) sensor reading of this measurement was made.
Interval
2
This 2 byte encoded 6 bit binary encoded (see below) number
tells the measurement interval in minutes or the amount of time
between readings of this measurement.
Measurement
Data
3 for each sensor
reading
Measurement data collected: This data contains only those
measurements set up to be included in the transmission (see Tx
Data Content). The data values are 3 byte binary encoded signed
numbers allowing a range of -131072 to +131071. The actual 6-
bit binary encoded format is described later. The value
transmitted will be value * 10^RightDigits. The string /// will be
sent if the data was never measured or was erased.
All the required values for one sensor (most recent first) before
proceeding to the next measurement. This format is similar to
that used by the Sutron Satlink but different from the 8210.
There will be 3 bytes of encoded data for every sensor reading.
The number of readings depends on the user setup.
Additional
Measurements
Variable
If more than one measurement was set up for transmission,
more data will follow. Each measurement setup will have data
starting with the Measurement Delimiter and ending with
Measurement Data.
Final Delimiter
1
This byte is always . and it is used to denote the end of all
measurement data.
Battery voltage
1
This is the battery voltage measured prior to making the
transmission. The range of the number will be -32 to +31 and can
be converted to volts by multiplying by 0.234 and adding 10.6
allowing a range of 3.1 to 18.1 volts.
