9.   Diagnostic Provisions 

9.1.  Overview of Diagnostics 

Internal to the 

RV-M80-EA2 

radio modem, is a powerful 32-bit microprocessor.  

Along with handing all aspects of radio modulation and demodulation, the 
microprocessor also maintains an extensive array of diagnostic information.   

This section details the diagnostic information available, and describes how to us 
the information to optimize or troubleshoot a 

RV-M80-EA2 

radio network.     

9.2.  Reading the Diagnostic Information  

RV-M80-EA2 

diagnostic information is read using AT commands, while the unit is 

in the Command Mode.  Refer to the section “User Serial Port Commands” to 
learn how to put the 

RV-M80-EA2 

modem into the Command Mode.   

To see a general overview of how the modem has been operating, us the 

ATST

 

command (status request command), without any parameter.  The radio modem 
will respond with a list of certain operation statistics that it maintains.  All statistics 
start counting at 0.  The 

ATST 1

 command can be used to reset all statistics 

back to 0, except the run-time timers. 

Other operation and configuration statistics are available using the ATST 
command, with a parameter to specify the desired statistic.  The following table 
describes the various statistics available.
