Messages from the XMR
There are several messages sent from the XMR, depending on setup and conditions. Below are
examples of the most common Mobile Originating messages.
Settings Summary Message
On startup, the XMR will send a summary of timers and a short list of GPS and Iridium settings to
confirm to the user the immediate configuration of inactive (Timer Zero) and In-Motion (Timer
Two) timers.
These settings can be seen below in the Settings section.
Version (Type V)
The $ver command will return a summary of both firmware and hardware versions:

Position
Typical position messages are sent in compressed binary format (Message Type 10) to save on
data usage and are parsed in XeosOnline. If XeosOnline is not used, GPS Text Short (Message
Type 0) can be used to read position messages as P-Type.
Compressed Binary Position
The default format for positions is compressed to save on Iridium data usage. This binary format
is parsed into a readable format by XeosOnline, placing its full contents in the Message and
Location Logs.
The binary format is stackable and can transmit more than one position per Iridium transmission.
In this situation, all recorded positions will be displayed in the Location Log, while the latest
position will be displayed in the Message Log.
