Web Apps: Assist App

Assist App requires at least one 52-8512 Assist App license in your core device. See Licensing for details on how to enter licenses to the device.

Assist App in the Web requires a recent browser. DHD recommends using one of the recommended browsers with at least the tested version as listed in Recommended Browsers.

Assist App supports RX2, SX2 and 52/TX surfaces.

Assist App is fully optimized for multi touch and mobile devices.

When the configuration is done, you can visit the Web Apps page of the DHD core.

  1. Open your web browser. See System Requirements for DHD Software for a list of recommended browsers.
  2. Enter the IP address of your core:
    http://[IP of core deivce]


    The Web Apps interface starts.

  3. Click Assist app icon. If:
    1. You have only one console configured for using it with assist app in the web, the console will open directly
    2. You have more than one console configured for using it with assist app in the web, a list of available consoles will show up
    3. You have password protection / authentification enabled, log in first. See user authentication.

If the screen remains blank or you see No License Available (use system app to check license), check if you have a valid license and it's not already taken.

One open connection via web browser requires one 52-8512 Assist App license.

Use left button to display the whole console width on your screen and get a better overview of the whole console.

Use right button to expand the console to the maximum available height on your screen and make control of elements more easy and accessible.

You can use the browser's integrated zoom. This will inactivate the scaling buttons and result in Broser zoom is active, Console-Zoom deactivated message. Use them to restore correct fit again.
