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, serial data pattern matching, signal
strength (RSSI), or data usage. Alarm conditions include:
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:
–
–
Send alarms based on average RSSI level below threshold for amount of time: Send
alarms based on the average signal strength falling below a specified threshold for a
specified amount of time.
–
–
Note
Send alarms based on cellular data exchanged in an amount of time:
–
–
–
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.
RSSI: The threshold signal strength, measured in dB (typically -120 dB to -40 dB).
Time: The amount of time, in minutes, that the signal strength falls below the threshold.
Data: The number of bytes of cellular data.
Time: The number of minutes.
Cell Data Type: The type of cellular data exchanged: Receive data, Transmit data, or
Total data.
enabled, this option causes an optimal alarm to be sent when the signal strength
returns to a value that is above the specified threshold.This feature is only available
through the command line. The default for this option is no; it must be explicitly
enabled if desired.
The set alarms command has an option, optimal_alarms_enabled={yes|no}. If
