9.1. Overview of Diagnostics
Internal to the
RV-M8-UC
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-M8-UC
radio network.
9.2. Reading the Diagnostic Information
RV-M8-UC
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-M8-UC
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.
