Data Relay
The XMR allows for serial relay functionality, sending data to and from a connected serial
peripheral device over the Iridium Satellite Network.
The XMR has a single RS-232 pair with which to communicate with the device for relay of external
data to and from Iridium, or to monitor diagnostics.
On start-up, diagnostics will be disabled on the XMR, but can be enabled by issuing the command
$diag 1, and disabled with $diag 0. The XMR will accept commands and send appropriate
responses in either “diag” state, but not stream more detailed diagnostic data when diagnostics
are off with the exception data incoming over Iridium from the $outport command. The XMR will
always accept commands over Iridium.
Serial Relay
To send data to or from a connected serial device, connect to the serial port on the XMR. By
default, the XMR will use these connection settings:
Baud Rate 57.6k
Parity None
Data Bits 8
Stop Bits 1
In the event the peripheral device has a different baud rate, the XMR can be changed to match
for communication purposes using:
$baudrate XXXXX Y
XXXXX Baud Rate
Y Stop Bits (0 or 1)
The XMR will immediately use the commanded baud rate, but this setting does not survive
resets.
