XMR User Manual 1.1 19
Mobile Terminated SBD (To Device)
To send a payload of data to your connected serial device via the XMR, create a file with the
extension “.sbd” with its contents adhering to the following format:
$unlock 12345
$outPort 1
payload line 1
payload line 2
payload line 3
Again, all lines are terminated with either a carriage return, line feed, or both. The unlock line
will be a 5 digit numerical code, unique to each device. Its purpose is to prevent accidental or
malicious commands from being processed by either the XMR, or your connected device.
When the data to be sent is compiled, normal methods of sending commands to Iridium devices
can be implemented, either through email or a web service such as XeosOnline. Remember that
XeosOnline will remember the unlock code of the device, so long as it has received it in the past
and it has not been changed. As such, it does not need to be added to the command block being
sent.
All lines after the “$outPort 1” line will be delivered to the connected serial device the next time
the Apollo Relay is scheduled to contact the Iridium network
.
The total message, cannot exceed
270 bytes. Upon reception of the $outPort 1 command, the XMR would output the following
data to the connected serial device, according to the above example:
payload line 1
payload line 2
payload line 3
Check Iridium Mailbox
In cases where no data is to be transmitted out of the XMR, but incoming messages may be
expected, the following command prompts an immediate Iridium “Message Check:”
$imsgchk
