bor
Brownout Reset Event
This is the number of times the MPU has been reset due to a
Brownout reset, the voltage threshold is set at 2.7V. This should
remain at 0, anything else could imply PSU problems.
extr
External Reset Event
This is the number of times the MPU has been reset via the reset pin,
this should be 0 after it has left production, any other value here
could imply a board fault.
on
Boot Sequence calls
Number of times the RF500A/AP has been through the boot
sequence, a high number could indicate constant resets indicating an
intermittent fault. Over time this number could become high
naturally.
Audit Trail Information

Message
Comments
RF network reset
The RF system has instantiated a new network.
Gateway switch on, from abnormal shutdown/reset (0)
The RF500A/AP has started up but not been able to detect the
reason for the last shutdown.
Comms Error with HW, () “command name”
A communications error has occurred between the website
software and the control MPU on the main PCBA. The actual
command that failed will be listed.
Restart cipher-host 2 no1=0 no2=0
The RF software has been reset, this could be due to a crash or
a handled exit point as described in the section emberlog2. If
“no2=0”
this indicates the RF software has never been able to
communicate to the RF module.
Gateway SW Fault, commsmon
The RF500A/AP has detected that one of the programs that
make up the system has crashed. The program name will be
listed, in this case
“commsmon”
has crashed.
System Update Error
During the software update process an unexpected error
occurred.
New pc mother board found
The RF500A/AP has detected that the PC module has been
changed, this will mean the MAC address will also change.
Ember software stopped, possible hardware fault
The RF software on the PC module has detected a
communications error with the radio module.
super user mode
The RF500A/AP has detected that a user has logged in via the
command line as the root user (this could be over SSH or the
USB interface).
Last Shutdown due to low batteries
The RF500A/AP shutdown due to the internal battery pack
reaching critical discharge value.
Hardware Fault on Gateway, over heat
The RF500A/AP internal temperature reached the over heat
temperature which will trigger the thermal shutdown event.
Hardware Fault on Gateway, battery pack
temperature fault
The temperature sensor in the battery pack is faulty or the
pack has overheated.
Hardware Fault on Gateway, External power fault
The RF500A/AP has detected the external PSU is faulty.
