  1. Setup the Chromecast Audio device as usual, join into your WLAN
  2. Connect the Chromecast Audio on any analog input of any Control4 Controller
  3. Add this modified Chromecast driver to the Project and connect in Composer the audio output to the Controller input. Its name will be shown in Composer as Chromecast Audio. nocontrol_google_chromecast_audio
  4. That’s it. Refresh Navigators and enjoy!

How to replace GT KNX dimmer and switch drivers by C4 dimmer and switch drivers

The process is identical for switch and dimmer, in this example we take a look at a dimmer driver which needs to be replaced.

  1. Make sure you have updated the driver to Version 10.6.2 or higher. Go to Driver -> Add or update Driver and select the driver file.
  2. Check version by right clicking on the driver
  3. Refresh the project in Composer by pressing F5 or File -> Refresh
  4. If the version is correct add a new KNX Dimmer driver from the online database to the project.
  5. Jump to the old driver and select in the popup window of the Property Replace with C4 Dimmer driver the new inserted KNX Dimmer driver.
  6. Press Set
  7. Jump to the new driver and see if all Properties were correct transferred.
    The driver name also is taken over, and the old driver is marked with obsolete.
  8. Buttons connected to the old driver were also transferred to the new driver
  9. Delete the old driver, AFTER you have checked Programming if there is anything to do.


Kaleidescape Co-Star for Creston NVX available

The Kaleidescape Co-Star for Creston NVX solution is now available, with the purchase of a special Co-Star for Crestron software license.  This solution allows Strato movie players to present a unified onscreen library that includes all of a Kaleidescape customer’s movies – from DVD discs to downloaded 4K HDR movies – in one seamless interface. Co-Star allows the movies on both a Strato system and a Premiere system to be played from a single user interface.

With the Co-Star for Crestron feature, Strato players are paired with Kaleidescape M-Class players using Crestron DM-NVX encoder/decoder devices, which can switch between video sources and transport 2160p60 4:4:4 video over standard Gigabit Ethernet. NVX devices are controlled using a Crestron control processor, and the Kaleidescape module for these processors has been extended to allow Strato to direct the NVX devices to switch between players, enabling playback of movies from both systems.


Configure a Cisco Small Business Series Switch for Swisscom TV

Task description:

Using Swisscom TV in small environments is rather easy, just connect all Swisscom TV boxes into the Swisscom router and you are ready to go.
Looking to larger installs, specially in the residential area, this setup structure is often not an option as the complete in-house network is managed by a IT company or it has a network structure which does not follow the Swisscom guidelines.

The Cisco Small Business line of switches works usually very well for residential installations, for Swisscom TV they need a special configuration.

As specifications can change, this howto may only be a guideline, is has no intention to be absolutely correct.


  • Swisscom router which connects to port 6 of the switch
  • Swisscom TV box on port 7  and 8 of the switch
  • VLAN 20 is used for all Swisscom TV data
  • Cisco SG300-10, firmware (or higher)
  • IPv4 is used


  1. Log in to the switch and go to VLAN Management -> VLAN Settings, create a VLAN for the Swisscom devices
  2. Assign the ports to the VLAN
  3. Under Multicast -> Properties  activate and select the VLAN in the drop down. Activate for IPV4 the forwarding method IP Group Address
  4. In Multicast -> IPv4 Multicast Configuration ->IGMP Snooping activate IGMP Snooping Status and IGMP Querier Status
  5. Select VLAN 20 and hit Edit for additional settings
  6. Multicast -> IPv4 Multicast Configuration -> IGMP VLAN Settings.
    Select the VLAN 20 and set accordingly
  7.  If the switch still is flooded an additional setting can be done under Multicast – Unregistered Multicast.
    Activate filtering of all unregistered multicast.

Symetrix triggers ADA PTM-1645 and Lexicon DD-8

Have you ever heard a Symetrix Radius or Edge combined with a ADA PTM-1645VC or a Lexicon DD-8?

Even though that combination  sounds good, its a breeze to combine them technically. No need to trigger over control systems, doing whatever programming.

ADA PTM-1645
Using this prebuild super-module for Symetrix Composer all PTM’s can be controlled from one serial port of a Symetrix unit. Setup instructions are inside the supermodule
Daisy Chain of PTM’s is supported.
Cabling: Symetrix RX goes to ADA ring, TX to tip, ground to ground

PTM-1645VC Trigger


Lexicon DD-8
The DD-8 needs to be controlled over a single trigger, using one control output of a Symetrix unit.  All 4 zones of the DD-8 are supported, merged.
Setup instructions are inside the supermodule

Setup a Cisco SG300 / 500 switch for Dante

  1. Update the Switch to the latest firmware and boot code
    1. Before you start make sure you have a TFTP client installed on your PC, if not you can use Solarwinds TFTP Server. Once installed download the latest Firmware from the Cisco website.Open Solarwinds TFTP server go to File -> Configure and set the TFTP Root Server Directory to the folder you have placed the Firmware files.
    2. Start the Service and close this window. The bottom bar of the main window should now confirm that the server runsCropperCapture[510]
    3. Make sure all firewalls are disabled or correct configured.
      Log in to your switch and go to Administration -> File management – >Upgrade… and select to upgrade the firmware.CropperCapture[512]
    4. Follow the procedure displayed by the firmware upgrade process. Once done upgrade the boot codeCropperCapture[513]
    5. Again follow the procedure displayed by the firmware upgrade process.Then select to use the new loaded firmware on the next start
    6. Do a reboot, Administration -> File management – >Reboot.
      Let your switch reboot, it takes some minutes. It will look like dead for a while, do not do anything, don’t unplug the mains, it will boot fine.Its important that all switches have the same firmware version, do this procedure on every switch in your network, or at least on the ones that are used for Dante
  2. Set the switch to a static IP settings
    In Administration ->Management Interface -> IPv4 Interface set the switch to a free static IP
  3. Define DNS settings
    Enable the use of DNS in IP Configuration -> Domain Name System -> DNS Settings and add at least 2 known good DNS servers to the list
  4. adjust system time
    A very important thing is that the switches are synchronized in time. Not only that the logs are more clear if time is right, the complete network management traffic between the switches is taking advantages of a correct time.

    1. Administration -> Time settings -> System Time enable the Main Clock Source (SNTP Servers) and set also the correct time zone
    2. Enable afterwards the SNTP Client Unicast in Administration -> Time settings -> SNTP Unicast and add at lest two time sources
      If the config is correct the status is up and the Last Response is accurate
  5. Create a VLAN for Dante
    We assume here that you are already logged in in the Switch..

    1. To create a new VLAN go to Vlan Management -> Vlan Setings an add a new one
    2. Next we have to define which port that contains traffic for that virtual lan. But before we have to define the capabilities of each port in therms of VLAN. 3 different port settings can be set in Vlan Management -> Interface Se tings. From Cisco manual:
      1. General—The interface can support all functions as defined in the IEEE 802.1q specification. The interface can be a tagged or untagged member of one or more VLANs.
      2. Access—The interface is an untagged member of a single VLAN. A port configured in this mode is known as an access port.
      3. Trunk—The interface is an untagged member of one VLAN at most, and is a tagged member of zero or more VLANs. A port configured in this mode is known as a trunk port.
    3. So for us that means that all Dante devices must be connected to a port that is set to access, all ports that are connected to other switches must be Trunk or General
    4. After we have set our port settings right we do assign which VLAN goes over which port.
      A trunk usually transports all VLAN’s to the next switch, therefore we can set the uplink port to transport all VLAN’s
      The picture above show that port 1-5 are uplinks to other switches 6-8 are access ports for simple Dante devices. UP means that this VLAN (usually 1) is the default non tagged Lan which is assigned on the port (If you connect your PC without VLAN config on the network card you end up in this network).
      T means that this VLAN is tagged only available on this port. The pages VLAN Management -> Port VLAN Membership and VLAN Management -> Ports to VLAN do show and set the same settings.
  6. Disable Energy Efficient Ethernet EEE
    Anyhow the Cisco switches are very good in saving energy and disabling partially the ports Dante can be affected by such events. Therefore this service should be disabled. (Not every switch does support EEE, if not available its not built in)
    In ports overview it should look like that
  7. Multicast settings
    Dante supports IGMP, a communication protocol to manage multicast. Using that protocol the switch can manage multicast’s and decide which port should be included in the multicast, save CPU and port capacity for ports that are not involved.

    1. First we have to enable the Bridge Multicast Filtering Status in Multicast -> Properties for the VLAN we use for Dante. As Forwarding Method select IP Group Address
    2. Each VLAN needs to be enabled with IGMP. In Multicast -> IGMP Snooping select all vlans which contains Dante traffic and enable the IGMP snooping status
    3. Select each IGMP enabled VLAN and press edit. Do the following settings
      Important: If there are multiple switches in the setup only activate the IGMP Querier on one switch and configure the Multicast Router Port accordingly.
      IGMP querier does only work if the switch has a IP  address in the same network segment it should query (Querier Source IP Address). Take care if you have VLANS on different network segments, the switch must have a matching IP to send the query’s. Maybe Layer 3 must be activated to achieve this…More info on multi- switch IGMP config: From this step on our switch auto-detects multicast ‘s and forward them to the ports needed. This auto-detect needs to be tuned a little for Dante.
    4. The table in Multicast ->IP Multicast Group Address shows the already detected multicast IP addresses, as well custom addresses can be inserted. So we make sure the two addresses (PTP) and (MDNS) are in this list and assigned to the ports needed (Ports that are included in the Dante VLAN) as static
    5. Looking at Multicast -> Multicast Router
      The different settings static, Forbidden, None are explained in the help of the switch. Dynamic means that the switch has detected the port already, so change this to static. Once changed, the switch knows already the correct settings, so after a power loss the right settings are immediately applied, the auto detect delay is gone.
    6. For uplink connections from switch to switch also activate in Multicast -> Multicast Router Port the port to static forward all traffic.
      The picture above shows that port 10 is an uplink, port 1 is not disturbed in any case with Dante multicast’s. For devices which are maybe in the same VLAN but are not Dante devices the setting forbidden should be chosen. The two multicast addresses we added are now registered multicast’s, means the switch knows exactly what to do with the traffic.
    7. For Dante audio multicast’s and other devices multicast’s we need to make sure that the unregistered multicast’s are  forwarded and auto-detected. Multicast -> Unregistered Multicast let us define exactly this settings. Port 1 does not need any multicast, therefore we define Filtering for this port. All other are in Forwarding mode.
  8. Setup QoS to prioritize PTP (Dante clock messages)
    1. Quality of Service -> General -> QoS Properties set the QoS mode to Advanced
    2. Then we have to correct the queue settings
    3. Quality of Service -> QoS Advanced Mode-> Global Settings we need finally to set the Trust mode to DSCP and the Default Mode Status to Trusted
