end up with inconsistent transmission data content. In that case, disable Skip First Missing, and increase
the Sensor Cutoff Offset.
Sensor Cutoff Offset helps prevent missing data in a transmission by specifying how old the newest
measurement in the transmission may be. The default value for the offset is zero.
Let us continue with the example above. With the Sensor Cutoff Offset at 00:01:00, the transmission
scheduled for 12:31:00 will look for the first measurement to have been collected at 12:30:00. If the
Sensor Cutoff were 00:05:00, then the system would not try to include any data collected after 12:26:00,
which would cause the system to use the 12:15:00 reading as the first one.

Append Options
The "Append Options" add information to the end of the transmitted data. Not all options are available
for all transmission kinds. Not all transmission formats support all the append options.
ASCII Column format does not allow any append options.
All the other formats support all the append options.
The options are listed below.
Use SHEF Codes for Options
This setting is not an append option per se; it controls how the headers for the other append options. If
selected, standard SHEF codes are used as the headers. All the examples below use SHEF codes.
Battery Voltage
The battery reading measured prior to the transmission. Example: “:YB 12.50” would be formatted if the
voltage were 12.5.
Station Name
The station name option appends the customer entered Station Name setting. For Iridium telemetry, this
setting also controls whether the station name is included in the transmission header.
If the station name were “Small Creek”,
it would be formatted as “:YN Small
Creek
”
Tx time
The time of the current transmission expressed as HHMMSS. ":YD 131015" is used for a time of 13:10:15.
Serial no
This is the serial number of station. The SHEF format would be “:SN 00001" where 00001 is the station
serial number.
