receiver. Additionally, CRC mode causes the S571 to store and later retry each alarm until a proper
acknowledgement is received from the receiver.
If Require Asentria Alarm ACKs is enabled, the S571 will require a positive CRC mode response or it will
disconnect and retry the call. To enable CRC, the receiver must respond with the following after the header is
received:
(ACK)01(ACK)
Once CRC mode is enabled, each alarm must be acknowledged by a message in the following format:
(ACK)
XX
(ACK)
XX
represents the alarm ID to acknowledge. The ID can be found in the first line of each record sent by the
S571.
Alarm Transmission
After successfully initiating a session, alarms are delivered in the following format:
(SOH)ID=XX(SOT)
Date=12/25/07
Time=10:30:02
TargetPort=
TargetName=
AlarmType=Data Alarm
AlarmName=Test Alarm
Threshold=0
Severity=Critical
Text1=text record line
Text2=text record line
(ETX)XX
(CR/LF)
(CR/LF)
The alarm ID indicates the index number of each alarm delivered during a call. This number restarts at 1 for
each new call.
The severity line represents the Class value defined for this alarm.
Up to twelve lines of Text
n
may be sent.
XX represents the 16-bit CRC if CRC mode is enabled. If not, this line will contain two spaces.
If additional alarms are queued to send in the same transmission, the above output is repeated, and the ID
incremented with each alarm. When non-CRC alarm transmission is selected, alarms are sent with a 5
second delay between each. When all alarms and been transmitted, then S571 sends the following:
(EOT)
(CR/LF)
(CR/LF)
At this point, the S571 waits 20 seconds for the receiver to send any input, and then hangs up. If any
commands are received, a command prompt is established and the connection will remain active.
Action Definition
Asentria Alarm actions are designated by "M" in action definitions. The numbers correspond to callout
numbers.
Example: Modem(1), Modem(2), etc.
SMS Alarms
Note:
SMS Messaging is only supported with an EDGE wireless modem installed in the S571.
SMS alarm messages contain a concatenated alarm string, which follows the format of:
