Pseudobinary-B Format
Name

Description
Block ID
1
BLOCK-IDENTIFIER is always sent as "B" to indicate
that this is the pseudobinary B format.
Group ID
1
GROUP-ID can be "1" to indicate a scheduled
transmission, “2” meaning an alarm transmission, and
“3” indicating a forced transmission.
Delta Time
1
Age in minutes of the most recent data
Data
3x num sensors
Data in either interleaved, or non-interleaved format.
The example above shows the data interleaved (most
recent of all sensors followed by next oldest, and so
on). See the section below, “Six-Bit Binary Encoded
Format” for details on how these values are encoded.
Battery
Voltage
1
Logger battery voltage measured just prior to
transmission
Pseudobinary-C Format
The Pseudobinary-C format also produces an ASCII report of 6-bit pseudo-binary formatted
values, but with additional fields to describe label and time information. Just as the “B” version
of the format, this format is “pseudo”-binary, because each sensor value and descriptor is
expressed in the range of ASCII characters, but not in such a way that is readily human-readable.

Description
Block ID

BLOCK-IDENTIFIER is always sent as "C" to indicate
that this is the pseudobinary C format.
Group ID

GROUP-ID can be "1" to indicate a scheduled
transmission, “2” meaning an alarm transmission, and
“3” indicating a forced transmission.
Measurement
Delimiter
1
This byte is always a “+” and it is used to denote the
start of measurement data.
Measurement
Index
(Sequence)
1
The Sequence number assigned by user in the output
telemetry settings. This value is encoded 6 bit binary.
Typically, the sequence number assigned is unique,
allowing you to uniquely identify the data point.
