Options <opt>
The Options <opt> string is a two character hexadecimal representation
of an 8 bit value derived from the following table. The user determines
which data is needed and selects that bit value. Once all selections are
made the values are summed bitwise and then converted to a two
place hexadecimal value. To aid in the conversion, a 4 bit-to-
Hexadecimal conversion table follows in EXAMPLE 3.
Options: Bit Value Identifiers
Serial output Options <opt> parameter: select the desired status messages from this list
which will appear in the MESSAGES column, add the bit value for each column bitwise, and
convert into two hexadecimal characters using the 4 bit-to-Hexadecimal table in EXAMPLE 3.

Example 3:
The user wishes to implement the “G”
command (“Go”command, refer to LEVEL 1
COMMANDS table) to have the following
serial output columns reported from the
monitor: Time Stamp, Capacitor Reading,
Overall Hydrogen Reading, the Peak
Hydrogen Reading, Calculation Errors, and
the Heater state.
From the FORMAT <fmt> table above, you
identify your desired columns with its
corresponding bit value:
