How to set up an Association to Listen to a live view as well as Trigger a Light To notify Employees they are Being Actively Listened to

Description 

If any customer is wanting to set up an event to trip when selecting 2 associations on live view to trigger a light to alert employees they are being listened in on.

Product USBDIO Module:

Steps to Reproduce 

The task was to create a live view association as well as a trigger to turn on a light when a Manager is listening to the live video feed in the client.

  • Step 1 Once the USBDIO module is connected navigate to the Trigger Input section in the Client and name the device.
  • Step 2 Name the Output that will trigger the light to turn on.
  • Step 3 Set up the Association for both buttons to show on the live view of the camera.
    The first association to create was the listening option for the camera.

Then next association is for the Event linking to turn the light on. This will be found under the USBDio Module in the list under associations.

  • Step 4 Create The event linking for the soft trigger and the Trigger input to turn the light on.
  • First the Soft Trigger: First select the Event Type for Soft Trigger. Then Create a new Event Source and name it accordingly. Select an Action Type of output trigger. Then For the action target select the Output. In this example it was the name Alert Light since the Module’s output will turn the light on or off when the button is enabled in live view.

Next create the Event linking for the Input Trigger. For the Event Type select Input Trigger. Then select the Event Source from the usbdio module which is the Reception Light. Action Type would be the output Trigger and Action Target is the Alert Light.

Once that is done you should be able to go to the live view and select both the association buttons to trigger on. This will allow listening to the live view as well as turn on a light to alert employees they are being listened to. The output could be a speaker, a light, globe. It should be able to be used in any case as long as you select the proper output/inputs, associate them properly, and then create the event linking to trigger the event.

Configuration for USBDIO Module with a PIEZO Speaker and Power Supply

This is a guide for configuring the client if you are powering a PIEZO Speaker from a Power Supply.

Example:

In this example we are using the Relay for triggering an event base off of IP Camera Connection in event linking.
Notice the above picture that we are using Normally Open (NO) and the COM on the USBDIO Module to trip the speaker when the state changes off the module because the speaker has power from the power supply in this example.

If this is the case then proceed with configuration of the client.

In Alarm Outputs we want to configure the The OUTPUT 1 as the NO and COM relay that we are using. See figure for Example:

Once the Alarm output is set up go to Event Linking and configure a rule.

In this example we are using Event Type IP Camera Connection for the trigger.
Event Source will be the camera that we want to monitor.
Action Type is Output Trigger.
Action Target will be the Speaker that you labeled in the Alarm Outputs (Output 1).

What this will accomplish is that when the camera is disconnected or losses power takes place the USBDIO Module will be triggered by that event of IP Camera Connection and the output relay will change state and allow the speaker to alarm via the event linking that is set up.

Power Supply Alarm False Trigger

Problem

After an upgrade the server emits a Power Supply Alarm which is false. This happens on units with DIO boards. When the server is connected to EM a power supply alarm is triggered every 15 minutes.

Solution

This issue occurs due to a variable stuck in the sysmgmtpi.xml file. To resolve this the sysmgmtpi files need to be deleted.

  1. Stop the services
  2. Remove sysmgmtpi.xml from the C:\Program Files\exacqVision\Server folder
  3. Start the services
  4. sysmgmtpi.xml should be created again

USBDIO and Serial Port Recovery

The following recovery enhancements have been added to exacqVision Server:

  1. USBDIO recovery enhancement: version 6.7.20.74529
  2. UART serial ports recovery: version 6.7.25.75004

<br>

When a USBDIO or UART serial port device disconnects, exacqVision Server attempts to reconnect to the device after one second. If that attempt fails, the next attempt occurs after two seconds, and then four seconds, eight seconds, 16 seconds, and so on. This occurs until the device reconnects, or until the following maximum intervals are reached:

  1. USBDIO: 300 seconds
  2. UART serial ports: the same as the IP Camera reconnection interval

Removing an Unwanted USB I/O Device from a Server’s Configuration

If a USB I/O module was previously used and later disconnected from the server, the software will retain the configuration and the module will remain listed in the left-side navigation panel.

If you wish to permanently remove this device from appearing in the software, you will need to log in to the server’s operating system as an Administrator and perform the following steps.

Windows

  1. Log in to the operating system’s admin account.<br><br>
  2. Click Start, type services.msc, and press Enter.<br><br>
  3. Right-click on the ExacqVision Server service and select Stop. Keep the Services window open.<br><br>
  4. Browse to C:\Program Files\exacqVision\Server and rename the usbdiopi.xml file to usbdiopi.bak.<br><br>
  5. Back in Services, select ExacqVision Server and click Start.<br><br>

Linux

  1. Log in to the operating system’s admin account.<br><br>
  2. Open a Terminal window, by pressing CTRL+ALT+T, and type the following to stop the ExacqVision Server service:
    sudo service edvrserver stop
    • When prompted for the password, enter the operating system’s admin password and click Enter. You will not see the password as you type it.<br><br>
  3. Type the following single-line command in Terminal to rename usbdiopi.xml to usbdiopi.bak:
    sudo mv /usr/local/exacq/server/usbdiopi.xml /usr/local/exacq/server/usbdiopi.bak<br><br>
  4. Type the following in Terminal to start the exacqVision Server service:
    sudo service edvrserver start
