Alarm configuration
To configure an alarm, click on it. The configuration page for individual alarms has two sections.
Alarm conditions
For specifying the conditions on which the alarm is based, such as GPIO pin state changes, serial
data pattern matching, signal strength (RSSI), or data usage. Alarm conditions include:
Send alarms based on GPIO pin states: Click this radio button to specify that this
alarm is sent when the specified GPIO pin states are detected. Then specify the
following:
– Pins: An alarm is sent when the specified combination of pin states is detected.
High - pin is asserted.
Low - pin is not asserted.
gnore - pin state is ignored.
– Alarm recurrence time: Defines how often a new alarm can be sent. For example, if
the alarm recurrence time is 10 seconds then even if the pin states are detected 5 times
within a 10 second period only one alarm will be sent.
– Send reminders while GPIO pins remain in this state: If enabled, reminders will be
sent if the pins remain in the defined state for an extended period of time.
– Every: The number of seconds the pins must remain in the defined state for a reminder
to be sent.
Send alarms based on serial data pattern matching: Click this radio button to specify
that this alarm is sent when the specified serial data pattern is detected. Then specify the
following:
– Serial Port: The serial port to monitor for the data pattern. This field is displayed for
devices where more than one serial port is available.
– Pattern: An alarm is sent when the serial port receives this data pattern. Special
characters such as carriage return carriage return (\r) and new line (\n) in the data pattern
can be included.
