Crestron Driver FAQ's

Beta release currently available for testing.
September 2020
Crestron driver V69 is complant with Database 200+
This uses the Kazoo Server with API Gateway enabled.

Crestron Linn DS Driver

The Crestron drivers do not look for Linn DS/DSM players by their names but for capabilities. That is, searches for UPnP services of the Linn DS/DSM products and adjusts accordingly.
This allows new firmware features and new product support WITHOUT the need for any Crestron driver updates. Both drivers have the common capability:

  • Series3 Processor support
  • This works with other non-Crestron control points. That is, and changes by other control devices are shown in the Crestron panels
  • Presets to quickly access favourite music libraries
  • Smart Graphics GUI, in landscape orientation, with Linn Kazoo look and feel, but also re-skinable in an installer specific Look & Feel.
  • Tested with a 10 DS and 4 controller setup (More Linn DS or Controller setup may require more Crestron Processors)

When I select Music in Kazoo it does not play and there is no coverart shown. Also Control/Creston has no control

Go into Kazoo Server settings and check the Network settings.
If Kazoo Server is setup for a different network then the Music and coverart link are for this different network. Double check that Kazoo Server network settings are same the Linn DS/DSM network

The Gateway API will also be trying to communicate with the wrong network addresses.
