“Through the use of Asentria’s SNMP-Link, we can now remotely survey our entire network, including our security, power and alarm equipment. Their products are seamlessly integrated into our network, and help us avoid expensive labor and installation costs.”
Jim Wemette, Manager of Systems Engineer at Burlington Telecom


Event Sensor Reporting


A unique, yet often unknown feature of Asentria’s SNMP-Link SL81 is EventSensor™ Reporting. This allows internal or external sensors on a "client" SL81, SL61 or SL10 to report a change in their status via a network connection to a "host" SL81, which can then initiate some sort of action just as if the sensor was connected directly to it.


Configure the sensor on the “client” unit as you normally would, and then go to the Networking Settings menu on both the client and host units and select I) EventSensor Reporting Settings.


 
SNMP-Link SL81 EventSensor Reporting Settings
A) EventSensor Report To IP [0.0.0.0]
B) EventSensor Report To Port [4000]
C) Enable EventSensor Reporting Host [OFF]
D) EventSensor Reporting Host Port [4000]
 

Options A & B are configured on the client unit. A is where you enter the IP address of the host unit and B is where you select a TCP port to use.


Options C & D are configured on the host SL81. C enables it to receive event sensor reports from the client unit, and D is where you select the TCP port it should be listening on.


Obviously, Option B on the client unit should match Option D on the host SL81.


To better understand how this works, follow this simplified example:


Site A is an SL61 in New York with an ES-5 event sensor connected to it that measures temperature in a server room.


Site B is an SL81 in Seattle that is on the same WAN as Site A. The Site B SL81 has a connected ES-9 Relay module which can turn on a red light over a maintenance engineer’s desk. With EventSensor Reporting enabled and configured properly on both units, the Site B SL81 will show in its list of connected sensors, the ES-5 at Site A (see below) with (REMOTE) following the Alive indicator for that sensor.


 
SNMP-Link SL81 Sensor Events Menu
Name ID Alive Number Configuration
A) INTERNAL -------- - 200 1-TS
B) Site B ES-9 0B021782 Y 1 8-RL
C) Site A ES-5 0902137C Y(REMOTE) 2 1-TS 1-HS 8-CC
 


Site B has configured this ES-5, even though it is at Site A in New York, to trigger the ES-9 relay when the temperature in the New York server room reaches 85 degrees.


One hot summer day the temp in the New York server room soars past 85 degrees. The Site A ES-5 reports the high temperature to the Site B SL81, which then activates the ES-9 relay which turns on the light over the engineers desk so he knows the server room in NY is hot. He can then take the appropriate action and save the day.


To summarize, this feature allows a device in one location to cause an action at another location even though the two devices are not physically connected.
