CRC Mode
CRC mode exists to ensure that event notifications are delivered intact. Asentria Alarms delivered in CRC mode
have extra control characters and a 16-bit CRC included in each alarm to allow for error detection by the receiver.
Additionally, CRC mode causes the S530 to store and later retry each alarm until a proper acknowledgement is
received from the receiver.
If Require Asentria Alarm ACKs is enabled, the S530 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 S530.
Alarm Transmission
After successfully initiating a session, alarms are delivered in the following format:
(SOH)ID=XX(SOT)
Date=10/23/09
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 S530 sends the following:
(EOT)
(CR/LF)
(CR/LF)
At this point, the S530 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
