Sutron Corporation X-Link Operations & Maintenance Manual, Rev 1.63 5/24/2016 pg. 58
When X-Link is turned on, it keeps the modem on for ten minutes. During that
time, it will receive messages immediately. When it does receive a message, X-
Link 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 129.)
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
X-Link remembers the last message received since boot up. To see it, press the
Refresh button on LinkComm's Telemetry tab or issue the STATUS TX command.
5.5.1.
Sending SMS to X-Link
You can send a message to an X-Link using your cell phone. To find out the
phone number of your X-Link, have it send you a message first. To do so, use the
Send SMS button in LinkComm's Telemetry tab. X-Link does not know its own
telephone number.
X-Link will never send more than 4 SMS in reply to a command. As each SMS is
limited to 160 bytes, this means 640 bytes is the limit of any reply.
5.5.2.
How X-Link Deletes Incoming SMS
X-Link does not keep old SMS. After it reads each incoming SMS, it will delete it.
This ensures that the SIM card of GPRSLink does not fill up preventing future
messages from being received.
5.5.3.
Sending Messages to IRIDIUMLink
Email is used to send messages to IRIDIUMLink
The email message must be sent to Data@SBD.Iridium.com
