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.

Six-Bit Binary Encoded Format
The six bit binary format is used to encode numbers into displayable ASCII characters.
Notice that fractional numbers cannot be represented, so for instance a battery voltage of
13.04 volts set up with 2 right digits will be sent as 1304.
 A 1 byte encoded number can range from -32 to +31.
 A 2 byte encoded number can range from -2048 to +2047
 A 3 byte encoded number can range from -131072 to +131071
Binary encoded numbers are always sent most significant bytes first. The number itself is
broken down into 6-bit digits, and each digit is placed in one byte of data. The number
64 (ASCII "@") is added to each digit to make it fall within the range of displayable
