Data Vision Software (DVS) GUI window opens but doesn't show the interface.

Potential Symptoms

  • DVS GUI window opens but doesn't show the DVS interface. (may get a port 404 error at address 127.0.0.1)

Environment

  • Windows PC
  • DVS software

Cause

  • By default the DVS software looks at  localhost (127.0.0.1) port 80 if you don't specify a port after the IP in the address bar of Chrome. As a result, if the port has been changed in the software settings ( C:\Program Files\Daktronics\DVS\DVS_SERVER_4_4\services\WebServer.properties ) for a particular customer the software is listening on the custom port and will not respond to port 80.

Resolution

  • Check the port settings in the file above (Instructions in DD3445813)
  • Change the port to 80 in the WebServer file

Work Around

  1. NOTE- If you change the port to 80 and there is a port 80 already in use error (this will show in the command prompt window if DVS_SERVER is set up to start manually) you can change it to another port
    1. If you change it to another port you can either use Chrome at address 127.0.0.1:xx  where x represents the port number or
    2. You can right click the GUI shortcut
      1. Click properties
      2. In the Shortcut tab in the Target window add a colon and the port to the end of the address. For example- "C:\Program Files\Daktronics\DVS\utilities\Chromium\chrome.exe" --app=http://127.0.0.1:xx 
        1. xx in the example above represents the port number
