Spok Messenger Gateways: AIM/ADM

AIM/ADM Gateways in Spok Messenger are defined as ports that have one or more Alarm Dispatch Modules (ADMs) connected. They are used to configure, which ADMs should be polled on each port that uses the ADM Protocol, as well as the baud rate of this polling.

Once communication has been established, each Alarm Input needs to be configured. For more information on this process, please refer to Configuring AIM/ADM Alarms: Alarm Inputs.

Exactly one ADM Gateway per AIM/ADM port is defined. When viewing the AIM/ADM Gateways screen, all AIM/ADM Ports display in the leftmost panel of the screen. Because of this, you cannot add and delete AIM/ADM Gateways, they are automatically created and deleted with AIM/ADM Ports. 

If no ports appear in this panel, you must define at least one port to use the AIM/ADM protocol. For more information on this process, please refer to AIM/ADM Ports.

The fields in this screen are populated using the information entered for the AIM/ADM port. Choose Interfaces > AIM/ADM > AIM/ADM to display the AIM/ADM Gateways screen.

Baud

Baud refers to the serial communications speed of the ADMs attached to this gateway. For more information on how to configure the baud rate for the ADM’s, please refer to the Installation and Configuration Guide Alarm Dispatch Paging Module document.

Controllers

A list of the ADM modules that may be connected to the AIM/ADM Gateway and their current polling status displays in the Controllers window. A green tick indicates that polls are being sent to the ADM, whereas a red cross indicates that the ADM is not being polled. ADMs can be enabled and disabled by clicking on these icons.

Pass on undefined messages

When not selected, alarms for which no alarm input has been defined are not be forwarded further into the system. When selected, alarm activations and resets for which no alarm input have been defined are passed into the system.

Inputs on this port default to normally open

When selected, this option forces the default for all inputs which don't have an alarm input defined to normally open. When not selected, this option forces the default for all inputs which don’t have an alarm input defined to normally closed.

Allow alarm to be cleared by message receiver

When selected, this option allows the message receiver to cancel any alarms generated via this gateway. 

Keep alarms active when board failure occurs

When enabled, all active alarms will remain active if there is a loss of communication from the ADMs until communication is reestablished. At which point, any alarms that may have been closed during the outage will be closed. No duplicate messages will be sent for Active Alarms. When disabled all active alarms will close if there is a loss of communication from the ADM. When communication is reestablished any alarms that are still active will reactivate and new alarm messages will be sent.

 

After changing the polling status of any ADMs in an AIM/ADM Gateway, the Save button is enabled. Click this button to commit the changes to the database.

Once communication has been established, each alarm input needs to be configured. 

  • Test Selected: Clicking the Test Selected button allows a single poll to be sent to one or more ADMs to determine if they are connected correctly. If an alarm is active it is be reported. Automatic polling is enabled on correctly configured ADMs.
  • Multiple ADMs may be selected by holding down the Control key and clicking on multiple ADMs. A contiguous range of ADMs may also be selected by clicking on the first ADM in the range, holding down the Shift key, and clicking on the last ADM in the range.
  • Scan All: Clicking the Scan All button allows a single poll to be sent to each ADM to determine if they are connected correctly. If a valid response is received, Spok Messenger automatically enables polling of the ADM, otherwise it disables the ADM.
