Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 123
If your station is set up to make transmissions every 30 minutes, that means that it will take up to
30 minutes for Satlink to receive any messages sent to it. If that is too long, you may consider
turning on Listening. Please see the Iridium Setup section for more on Listening and message
checking.
12.1.4. Sending Messages to Satlink via Iridium
Satlink with Iridium can have messages sent to it via emails that get routed through the Iridium
system.
If Listening is enabled, Satlink receives messages immediately. In this mode, the modem is always
on, and the station consumes more power.
If Listening is disabled, Satlink checks for messages when it makes a transmission. If the station is
set up with a Tx Interval of 15 minutes, it may take up to 15 minutes for the station to receive the
message sent to it. With Listening disabled, Satlink turns off the modem between transmissions
to save power.
Additionally Satlink can be setup to do periodic message checking. No matter how it is setup,
Satlink will do a message check every 24 hours as long as it has power. Please see the Iridium
Setup section for more on Listening and message checking.
When Satlink is turned on, it keeps the Iridium modem on for ten minutes. During that time, it
will receive messages immediately. When it does receive a message, Satlink will keep the modem
turned on for ten additional minutes to facilitate additional message conversations.
Messages are treated like command line input with a few differences. Some commands cannot
be executed via a message (e.g. log download). Other commands may have a differently
formatted output (in order to reduce message size).
See the Sending Messages section in the Command Line Interface chapter for
details on what the content of the messages should look like. (page Error!
Bookmark not defined..) Do not forget to precede the commands with an
exclamation point if you want the station to reply.
To check the status of your station, send it the message
!STATUS
Password protected stations will need login information to be the very first thing in a message:
LOGIN=XXX; !STATUS
Satlink remembers the last message received since boot up. To see it, press the Radio Diags
button on LinkComm's Telemetry tab or issue the STATUS TX command.
Email is used to send messages to Satlink via Iridium.
The email message must be sent to Data@SBD.Iridium.com
