10.8 Transmission Data Content Settings
10.8.1 Tx Data Content
Tx Data Content indicates which readings to include in the transmission. Each measurement has multiple
Tx Data Content settings: one for each transmission.
The options are All Logged, Individual, Last, and Exclude.

By selecting All Logged , measurements that are logged according to the measurement schedule
are transmitted. Only readings made since the last transmission are included. This setting is
dependent on the
Logging Interval setting.

Please note that if the system is logging data more frequently due to being in alarms, the
extra data is NOT transmitted. To include extra data created by alarms, please use the
Last
option.

The only data points transmitted are those made according to the measurement time and
logging interval settings.

See below for the Individual setting.

Last means to transmit a set number of the most recent readings (determined by Number of
Values to Tx ).

Use Last for alarm and random transmissions to ensure that the value that caused alarms is
transmitted!

Last is the only option that may be used to transmit data that is not collected based upon the
measurement schedule.

By selecting Exclude , no readings of this measurement are transmitted.

All Since Last Tx includes all logged data since the last transmission. All Since Last Tx selection is
different from All Logged in that it ignores measurement scheduling. All Since Last Tx will parse
through the log and include every logged entry of the measurement.

This option is useful when the logging interval changes due to alarms or scripts.

This option results in a variable amount of data in the transmission. Only certain Tx Format
options are suitable for All Since Last Tx . Timestamps of transmitted data using SHEF, some
Pseudobinary, and all formats that do not give each reading its own timestamp, may be
incorrect. CSV and MIS will work correctly. Pseudobinary B is not suitable.

With All Since Last Tx , all estimates of data content may be incorrect.

With All Since Last Tx , newest data in transmission may be at (transmission time - Sensor
Encoding Time ). Oldest data will be newer than (last transmission time – Sensor Encoding
Time ).

Skip First Missing does not work with All Since Last Tx .
10.8.2 Tx Data Time, Interval, and Duration
If Individual is selected for Tx Data Content , the fields Tx Data Time , Tx Data Interval, and Tx Data Duration
will appear, allowing the choice of what data to include in the transmission.
These options may be used to measure and log data more frequently than to include them in
transmissions. They may also be used to transmit redundant data.
