MODE ID
CMD This is the Default Setting. Reponses from the instrument are encoded as the traditional command format.
Style and format of responses depend on exact coding of the initiating command.
Responses from the instrument are always delimited with <STX> (at the beginning of the response, <ETX>
BCC
(at the end of the response followed by a 2 digit Block Check Code (checksum), regardless of the command
encoding.
Responses from the instrument are always delimited with <CR> at the beginning and the end of the string,
TEXT
regardless of the command encoding.

The T100 Analyzer is a single gas instrument that measures SO
gas ID has already been set to 110. There is no need to change this setting.
Teledyne ML's implementation of Hessen protocols includes a set of status bits that the
instrument includes in responses to inform the host computer of its condition. Each bit
can be assigned to one operational and warning message flag. The default settings for
these bit/flags are listed on Table 5-15:
