Manual interface behaviour
The easy2log
©
RT0005 tag has a simple manual interface that includes a button, a green LED and a red LED that,
depending on the configuration, permits to check the status of the alarms and to start/stop the logging activity. By
default, the button can be used only to check the status of the tag but not to start/stop the logging activity. Start/stop
function can be activated setting the Button Enable (BE) bit in the CONTROL register.
The manual interface behaves as follows:
Pressing the button quickly (less than 2 second) activates the check status function:
If the battery level is still sufficient for the logging activity and no alarms are active the green LED will stay lit for 2
seconds.
If the battery level is still enough for the logging activity but there are active alarms the red LED will stay lit for 2
seconds. The alarms causing the red LED to ligth are:
Memory full (see MEMFULL bit in STATUS register description).
ETA alarm (see ETA_ALRM bit in the STATUS register description).
Bin counters alarm (see BIN_ALMR bit in STATUS register description).
Mean Kinetic alarm (see MKT_ALRM bit in the STATUS register description).
Shelf life alarm (see SHL_ALRM bit in the STATUS register description).
If the battery has not enough charge to continue the logging activity the red or green LED will blink for 2 seconds (the
green one in the case of no alarms, red in case of some alarms).
