Iridium Enable
The Iridium Enable setting may be used to completely disable the Iridium modem. If disabled, the station
will never power on the modem, and no Iridium features will be available. This setting is the equivalent of
disconnecting the modem from the board. It may not be set remotely.
Iridium Tx Station Name
This setting controls whether Iridium telemetry should include the station name in the header of the
message. Please see

11.4 Additional Telemetry Settings
11.4.1 Max Tx Time
This value dictates how long the system will keep trying to reach the server. If a connection is not made
during this time, the system will give up on the transmission and mark it as failed.
This value should be less than the Scheduled Interval.
11.4.2 Retransmit
The retransmit setting controls whether or not the station will automatically attempt to retransmit failed
transmissions. Please see section
13.4 R
ETRANSMISSIONS
for details.
11.4.3 Sensor Cutoff Offset and Skip First Missing
Some setups may result in sensor data not being available in time for transmissions. This is usually the
result of a sensor taking a long time to respond. While this scenario is uncommon, there are several
settings that may be used in order to prevent missing data in transmissions:

Skip First Missing

Sensor Cutoff Offset
When Skip First Missing is enabled (it is enabled by default), if the first reading that was slated for
transmissions is missing, the system will skip that reading and go for the next one.
For example, a measurement is scheduled for 12:00, 12:15, 12:30, etc. A transmission is scheduled for
12:31. With that setup, the system is supposed to include the 12:30 measurement in the transmission.
However, the system does not find that reading in the log. The system has two options at this point:

Skip the 12:30 reading and use the 12:15 reading as the first one (Skip First Missing is On)

Put a missing reading marker in the transmission (Skip First Missing is Off)
The most likely cause for a missing reading is the response time of the sensor. If the sensor takes several
minutes to respond, the reading is likely to be missing. However, if the sensor takes a variable amount of
time to respond, sometimes taking less than two minutes, and sometimes taking more, the system may
