CTRL4.png Control 4 Linn DS Driver

The Control4 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 Control4 driver updates.

IMPORTANT NOTICE

If you are installing Linn Network, DS or Kustom drivers into a system that already contains versions of these drivers older than version 147 you must update all of these existing drivers to the latest version as the connections and internal communication protocols have changed. To do this:
- Download the latest online version of the drivers by going to the Search tab, unticking “Local”, finding the driver and then right-clicking and selecting “Download Driver”.
- Update each driver by right-clicking on an instance of it in your project hierarchy, selecting “Update Driver” and choosing the driver file you have downloaded.
If a simple update does not appear to have resulted in a working system, you may need to reinstall the drivers:
- Delete all instances of all Linn drivers in your project
- Re-install the drivers and their connections. The previous stages are necessary to ensure that you get the latest version of the driver when you do this install; just deleting and re-installing can end up with an older version that has been cached on the Director.

Linn DS Series
The driver has the following read-only variables in addition to the standard variables defined by Control4:
Variable Purpose
INPUT_NUMBER Indicates which input is currently supplying audio to the room output:
-2 Songcast from a remote streamer.
-1 The local streamer.(Playlist/Radio)
0 Nothing
1..32 External input 1..32; see Properties to determine which input number corresponds to which input device.
Note that it is not guaranteed that the input number is 0 when the room is off, so programming should not rely on this nor on receiving a change in this value when the room switches on.

SOURCE_NAME The name of the currently playing source. Names are as defined on the DS using Konfig.
PAUSED true if playback is paused, else false.
PLAYING true if playback active, else false.
STOPPED true if playback stopped, else false.
PLAY_STATUS One of the following values:
PLAYBACK_STATE_IDLE Playback has stopped.
PLAYBACK_STATE_PAUSED Playback is paused.
PLAYBACK_STATE_PLAYING Playback is active.



Kustom DSM
The driver has the following read-only variables in addition to the standard variables defined by Control4:
Variable Purpose
ZONE_N_INPUT_NUMBER Indicates which input is currently supplying audio to zone N:
-2 Songcast from a remote streamer.
-1 The local streamer.(Playlist/Radio)
0 Nothing
1..4 External input 1..4; see Properties to determine which input number corresponds to which input device.
Note that it is not guaranteed that the input number is 0 when the room is off, so programming should not rely on this nor on receiving a change in this value when the room switches on.

ZONE_N_SOURCE_NAME The name of the currently playing source in zone N. Names are as defined on the Kustom using Konfig.
STREAMER_N_PAUSED true if playback on streamer N is paused, else false.
STREAMER_N_PLAYING true if playback on streamer N active, else false.
STREAMER_N_STOPPED true if playback on streamer N stopped, else false.
STREAMER_N_PLAY_STATUS A string value giving playback state on streamer N:
PLAYBACK_STATE_IDLE Playback has stopped.
PLAYBACK_STATE_PAUSED Playback is paused.
PLAYBACK_STATE_PLAYING Playback is active.
  • If you wish to update your Control4 from an earlier "Linn DS Series" driver, then we would recommend a fresh Project is created with V171 onwards
  • Or if you already have the "Linn DS Network (32 Players) + Pins" or "Linn DS Network (32 Players)":
IMPORTANT NOTICE
If you are installing Linn Songcast Network, DS or Kustom drivers into a system that already contains versions of these drivers older than version 170 you must update all of these existing drivers to the latest version as the connections and internal communication protocols have changed.
To do this:
- Remove any instances of the Linn DS Network or Linn DS Network + Pins driver in the system (these are replaced by the new Linn Songcast Network driver).
- For off-line drivers, that you have downloaded from above:
- In the top menu select Driver > Add or Update Driver or Agent
* Add each of the .c4z files one at a time
- For online drivers: Download and install the latest online version of the Linn Songcast Network driver by going to the Search tab, unticking “Local”, finding the driver and then right-clicking and selecting “Download Driver”.
- Download the latest online version of the any DS or Kustom drivers by going to the Search tab, unticking “Local”, finding the drivers and then right-clicking and selecting “Download Driver”.
- Update each driver either by using the Driver->Manage Drivers and Agents dialog, or by right-clicking on an instance of it in your project hierarchy, selecting “Update Driver” and choosing the driver file you have downloaded.
NOTE: It is important for the smooth installation of media player drivers that the network driver is added prior to the player drivers. The configuration of the player drivers cannot be completed without the network driver being in place and communicating correctly with a Linn CI-Gateway.


If a simple update does not appear to have resulted in a working system, you may need to reinstall the drivers:
- Delete all instances of all Linn drivers in your project.
- From the "Connect to Project" dialog that Composer shows when selecting a local system, right-click on your controller and select Terminal.
- Type the following commands at the terminal prompt (shown in grey):
~# cd /mnt/internal/c4z
/mnt/internal/c4z# rm -r comms_ip_linn*
/mnt/internal/c4z# rm -r mediaservice_ip_linn*
/mnt/internal/c4z# reboot
The terminal window will lose connection after the reboot and you can close it.
- Close all open instances of Composer.
- Re-open Composer and re-install the drivers and their connections.
The previous stages are necessary to ensure that you get the latest version of the driver when you do this install; just deleting and re-installing can end up with an older version that has been cached on the Director.

Setting up the CI Gateway for Control4 use

Linn CI Gateway

The CI Gateway is a piece of software that is required for Linn’s Custom Installation options – Crestron and Control4
This software discovers ALL all devices on a local network and then offers an API to retrieve information and control functionality for any Linn DS/DSM device on the same network. There are two ways of running the CI Gateway:
1. It can be run on certain Linn DS/DSM devices by enabling it in the system configuration (see below for supporting products).
2. Alternatively, if no suitable device is available then Kazoo Server can be used running on a PC, Mac or QNAP device. The CI Gateway is bundled alongside this media server software, and it simply needs to be installed on a suitable device on the local network. This is enabled through the Kazoo Server’s options.
Only ONE instance of the CI Gateway is required (i.e. no need to enable it on multiple devices). This single instance will allow control of ALL Linn DS products in the system. That is, this single instance will allow control of both older Linn DS products that cannot run CI-Gateway, and new Linn products that can run CI-Gateway.

Enabling the CI Gateway on a Linn DSM device.

The CI Gateway is available on any of the following Linn products:
▼ Gateway API
  Klimax DSM /3 (2020 Variant)
  Kustom DSM
  Majik DSM /4 (2020 Variant)
  Selekt DSM /0
  Selekt DSM /0 Classic Hub
  Selekt DSM /1 Classic Hub
  Selekt DSM /1 Edition Hub
  Series 3
To enable it:
1. Go to the ⁣Manage Systems page and login with your Linn Account.
2. Go into the options for one of your devices that is capable of running the CI Gateway.
3. Go into the Advanced tab and turn on the CI Gateway option. If your device is one of the above products and this option is not visible, then it could have outdated firmware – ensure it is updated and try again.
4. If the device is on, then you will be prompted to reboot the device. Once fully rebooted, the CI Gateway will then be enabled.

Accessing the CI Gateway Configuration

You can check that the CI Gateway is operating by accessing the configuration options page for it. For a CI Gateway running on a Linn DS/DSM device, it can be accessed through a web browser. You need to know the IP address of the device, and then it can be accessed through an HTTPS request on port 4100.
For example: https://192.168.1.49:4100
Note: if you know the MAC address of the Linn DSM running the CI-Gateway you can use its Device name derived from the IP address instead. For Linn DS with Mac address 00:26:0f:22:43:f7, take the last 6 characters and fit into avahi-linn-xxxxxx.linn.co.uk. To get into the CI-Gateway now, use https://avahi-linn-2243f7.linn.co.uk:4100
This will open the page below where options and configuration for the CI Gateway are located.

Centre

For a CI Gateway running on Kazoo Server, find the options page for Kazoo Server (for Windows, right-click on the icon in the system tray and click Configure Kazoo Server). You will then find an option for Gateway API. Clicking this option will give you the same configuration page.

Logging into streaming service accounts

It is possible to access third-party streaming services through the CI Gateway. You will see several of these on the configuration page. Some service such as TIDAL and Qobuz require logins for individual devices, but you can log in for all using the options at the top. Ensure these are configured before using any custom installation support.
Note: There is no need to log into Airable radio. Any Linn DS/DSM that is associated with a linn account has access to this server. If you are having difficulties, ensure that every DS/DSM is associated with a Linn account.

Accessing the CI Gateway Documentation (Advanced)

The CI Gateway is open to use by anyone! If you would like to write your own software that features control over Linn DS/DSM devices, then you are free to do so. There is documentation (under API Documentation in gateway options) that provides information about the API endpoints and allows you to try out its functionality. To use it in your own program, simply set up a WebSockets connection with port 8088 for CI Gateway running on a Linn DSM (or port 4100 for Kazoo Server) and send JSON messages across the connection using the format demonstrated in the documentation.

The first set of tabs (Session->Queue) are legacy endpoints that remain for older Custom Installation support. The session endpoints are the exception; these are shared between all support (the first step to using the CI Gateway is creating a session). Reworked API endpoints have been created more recently under the API V2 tabs of the documentation UI. These beta API endpoints allow for simplified and more intuitive communication, but may be subject to small changes.

Troubleshooting:

I cannot get any of the Linn DS/Streamer services to appear in Navigator

* The Service will only appear if you have the Linn DS connected to an Audio End-Point.
  • In Kustom DSM check that the Streamers are in (room) mode. (All configured Zones for each streamer MUST be attached to room Audio End-Point to bring this from (matrix) mode to (room) mode)
* If you are using this with a Matrix Switch then the Linn DS MUST be connected to Audio End-Point 2
* After installing the updated drivers, you will need to unbind and then rebind all the audio and video RoomControl connections to get the Streaming service to appear.

Sometimes my Control4 system operation slows down for a few minutes then works OK

This will be due to Control4 processor checking that all expected LInn DS players are alive. If one or more have been powered down or disconnected from the Network the Control4 will periodically interrogate the network for this/these missing Linn DS products.

In Tidal, I press the "Genres" button and Tidal stops working.

You are using an older verison of CI Gateway/Kazoo Server.
CI Gateway: Make sure you are using a Linn DS/DSM with Davaar100+ firmware
Or if you are using Kazoo Server check you are using V4.11.27+


I cannot control airable and/or Tidal on the Control4 touchpanel

Suspect that you are using Control4 driver V171, you are using an older verison of CI Gateway/Kazoo Server that is not compatible with V171.
CI Gateway: Make sure you are using a Linn DS/DSM with Davaar100+ firmware
Or if you are using Kazoo Server check you are using V4.11.27+
