Configuring Contact Closure Profiles

Last Updated: August 17, 2009

Each Cisco Analog Video Gateway module comes with eight contact closure interfaces. Four contact closure interfaces can be configured as alarm inputs or as contact closure relay outputs. The other four contact closure interfaces are for inputs only. Alarm interfaces can be used to detect contact trigger events and to control external devices.

The Cisco Analog Video Gateway is designed to interact with local or remote controllers to manage and control the contact closure interfaces. Alarm interfaces are set to their proper states and monitor trigger events. When an alarm is detected, the source and severity of the alarm are determined, the system log file is updated, and predefined HTTP messages are sent to the controllers. For example, in response to the nature of the alarm, the alarm can request the Cisco Analog Video Gateway to adjust the camera, begin video streaming, or trigger the external devices.

The Cisco Analog Video Gateway has eight preconfigured contact closure ports. The contact closure ports have the following default configuration. You can only modify a contact closure port; you cannot add or delete a contact closure port.

Use the contactclosure-port command to configure the specified contact closure interface profile.

Whenever possible, configuration and management of the Cisco Analog Video Gateway module should be configured using the Video Surveillance Operations Manager (VSOM) graphical user interface.

Note In the VSOM, the state change from open-to-close is considered falling and the state change from close-to-open is considered rising.

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 2 

contactclosure-port portnum

Example:

VSE-Module(config)> contactclosure-port 0

Modifying existing port

VSE-Module(config-contactclosure-port)>

Enters contact closure port configuration profile mode.

portnum: Contact closure ports. Integer value in the range of 0 to 7.

Step 3 

[default | description | direction | relaystate | state]

Example:

VSE-Module(config)> contactclosure-port 0

Modifying existing port

VSE-Module(config-contactclosure-port)> description "contact closure port 0 config"

VSE-Module(config-contactclosure-port)> direction in

VSE-Module(config-contactclosure-port)> relaystate close

VSE-Module(config-contactclosure-port)> state enabled

VSE-Module(config-contactclosure-port)>

VSE-Module(config-contactclosure-port)>

VSE-Module(config-contactclosure-port)> end

VSE-Module(config)> exit

VSE-Module >

Configures a contact closure port profile.

default: Contact closure default values. Use the no form of this command to remove the default values.

description: Contact closure text description in quotes. Up to 80 text characters are allowed.

direction: Contact closure for output direction applies only to ports 0 to 3. Contact closure for the input direction applies to all contact closure ports. Default: in.

relaystate: Contact closure relay state: open or close. Default: open.

state: Operational state of the contact closure port: enabled or disabled. Default: disabled.

Step 4 

end

Example:

VSE-Module(config-contactclosure-port)> end

Exits contact closure port configuration.

Step 5 

exit

Example:

VSE-Module(config)> exit

Exits global configuration mode.

Step 6 

show contactclosure-port portnum 

or

show contactclosure-port hw-state 

or

show contactclosure-port summary

Example:

VSE-Module> show contactclosure-port 0

Displays the contact closure configuration parameters for a specified port, displays the hardware state for all contact closure ports, or displays the contact closure port summary.

Examples

The following example shows the contact closure configuration parameters for a specified port 0: 

vse-module> show contactclosure-port 0 

description "contact closure port 0 config"

state enabled

direction in

relayState close

The following example shows the hardware state (open or close) for evert contact closure port: 

vse-module> show contactclosure-port hw-state 

0: close

1: close

2: close

3: close

4: close

5: close

6: close

7: close

The following example shows the contact closure port summary: 

vse-module> show contactclosure-port summary
