The Display Administration Suite (DAS) is designed to work with all our display types providing tools and services to monitor and manage every attached system through one integrated portal. It doesn’t matter if the display is an LTN-LCD, a HELIOS high bright with multiple media panels or a flip dot, whether it is handling multimedia or just plain bus information, the DAS knows what to do with it and provides you the tools to support your management tasks.

The DAS provides a great many functions, though naturally not all apply to all sign types. Access to the DAS is via the web. It is username and password controlled with configurations to restrict users to appropriate tasks.


  • Real time transit interfaces for live departure boards (supported data sources include GTFS, several custom formats, TransXChange and SIRI)
  • Messaging to all sign types with functions to group signs in various ways.
  • Remote views: a tool which asks the display to send back the bitmap it has created to push to the panel – hence this is not a theoretical view, it shows exactly what the display’s computer is putting on screen.
  • Status reporting: showing in list view or geographically, the status of every connected display.
  • Stop name editing: enabling the user to change the name derived from the transit feed (which may be clumsy) to one that is more appropriate and informative for on-screen use.
  • Pronunciation editor: enabling the user to enter and audition text which is used in place of the original data to correct poor pronunciation. So for example ‘Arkansas’ which might be spoken literally by the TTS and be pronounced wrongly, could be replaced by a phonetically correct text string.
  • Extensive media management: LCD panels may be configured to include regions which show video and static images in defined sequences. these sequences, called reels, are managed through the DAS which allows the user to define content, as well as how when and where it is shown. The system supports:

                  – Video (which will auto re-scale for different screen formats)

                  – Images

                  – RSS feeds

                  – Text (for example indication as to whether it is peak-hour ticketing)

       The user is able to schedule individual elements by setting:

                  – Target sign – including sign groups

                  – Date and date periods

                  – Time and time periods

                  – Locations (for mobile platforms only)


In order to make the process as simple as possible, the DAS includes some automated tools. For example

  • The system will automatically convert graphics files (stills and videos) to the optimum size and format for the relevant display region, irrespective of the supplied file type.
  • Behind the scenes. content is preconfigured to match the target display settings and type
  • The DAS takes care of making sure target devices have the content they need.


The DAS provides a sophisticated messaging tool, enabling the user to enter messages and send them to a sign or groups of signs. It supports four message types, the on-screen behavior reflecting importance: 

  • Normal: Usually configured to scroll on a separate message line 
  • Paged: Uses the space where the services are shown with the display swapping between the message and the services (the header area and the standard message ticker remain) 
  • Static: Permanently shown (until expired) on the space where the services are normally shown (the header area and the standard message ticker remain) 
  • Emergency: Message occupies the whole display area until the message is cleared.


The DAS includes functions to allow the user to monitor any equipment attached to the system. It includes: 

  • System status overview – a summary of equipment status, viewable as a map or a list 
  • Remote view – a static or moving display of the data being pushed to the screen 
  • Media schedules (where relevant) – confirming what media is scheduled to be shown and when 

Behind the scenes the DAS monitors many functions that are used to maintain an understanding of system function. 


The DAS is hosted on a server and uses a secure web interface. Whether this server is hosted by us or is located elsewhere, access is limited to users with logged user names and passwords. Users can be assigned access to specific areas only, thus ensuring that the client is able to restrict management tasks to selected personnel. 


The DAS uses a neat and simple web interface with easy to learn functions. Access is therefore possible from anywhere, provided the user has authorization.



The general principle we apply to our systems is that the displays should know everything they should know and nothing they should not know. So the DAS only sends data to the target device if it is relevant to that display and in the form it is required. That data is then stored in the sign. This minimises data traffic because data is only sent once (which is important if the signs are connected via mobile comms) and it ensures that if the communications drops out, the sign can carry on – the worst that will happen is it will not receive updates.

It doesn’t matter. Pretty much every standard format is supported: the DAS translates your file into the format, shape and size, used by the target device. You do not need to worry.

Yes, it does. All the normal functions work as usual, plus the system can be set up to show some content based on geographical location. It does this by allowing you to configure a valid period for a number of stops before a final stop. This means that, for example, information related to a hospital could be configured to show from three stops before the hospital stop until it reaches the hospital. After that, it won’t be shown. 

Yes. Our signs log on to our server and establish a VPN using the same secure transaction method as banks. Only once a sign is connected will it allow any data to be received and acted upon. In addition, the DAS has username and password protection so the service is protected, and you can choose what rights individual users can access.

User access is also controlled with username, password and predefined areas where they are allowed to make changes.

The answer, broadly, is yes. But there is an exception. If your display is the type to have a VGA, HDMI or similar video in, we can supply our mini computer (Aerak) which runs the software and outputs DAS content to your display. Of course you will not be able to retrieve the full diagnostic data from the display which the DAS gets back from our integrated systems (stuff like internal temperatures, fan function etc), but you will get remote views. If you want we can also supply units to be fitted inside a display, this is neater but still will not provide the diagnostics links to support some monitoring functions.
