Device Lock

Device Lock allows you to lock and unlock supported Dante devices using a 4-digit PIN (Personal Identification Number).

When a device is locked, media will continue to flow according to its existing subscriptions, and it can be monitored, but it cannot be controlled or configured – its subscriptions and configuration settings become read-only.

To configure a locked device you must first unlock it using the PIN with which it was locked.

Locked devices can be identified by:

  • A small gray padlock icon against the device name in the Network View > Routing tab  
  • A red background highlight when the device is moused over in the Network View > Routing tab
  • A check (tick) in the Device Lock column in the Network View > Device Info tab
  • A red padlock icon in the Device View toolbar 

Not all Dante devices support Device Lock.

To check if a Dante device can be locked:

  • Use the Advanced Filter to check for locked, unlocked and unsupported devices
  • Check the Device Info tab – devices that support Device Lock have a checkbox in the Device Lock column; devices that do not support Device Lock show ‘N/A’ in the Device Lock column
  • Open the device in Device View – if the padlock icon in the toolbar is blue or red, the device supports device lock; if it is grayed out, it does not support Device Lock
  • If in doubt, contact the device manufacturer

Locking a Dante device

To lock an unlocked Dante device:

Using Device View

  1. Open the device in Device View (Ctrl + D, or Command + D) and click the padlock icon 

    The Lock Device panel is displayed.
  2. In the Lock Device panel, enter a 4-digit PIN in the PIN field.
  3. Enter the same PIN in the Confirm PIN field.
  4. Click ‘Lock’.

The padlock icon will change to red    indicating that the device is now locked.

From the Device Info Tab

  1. In Network View, select the Device Info tab.
  2. Click the Device Lock checkbox for the device.
  3. Follow steps 2-4 from the above process.

Unlocking a Dante Device

To unlock a locked Dante device:

Using Device View

  1. Open the device in Device View (Ctrl + D, or Command + D) and click the padlock icon  
  2. In the Unlock Device panel, enter the 4-digit PIN in the PIN field.
  3. Click Unlock.

The padlock icon will change to blue    indicating that the device is now unlocked.

From the Device Info Tab

  1. In Network View, select the Device Info tab.
  2. Click the Device Lock checkbox for the device.
  3. Follow steps 2-3 from the above process.

Unlocking a Device When You Have Forgotten the PIN

If you have forgotten the PIN for a locked device, you can reset the PIN.

To reset the PIN for a locked device:

  1. Isolate the device from the rest of the Dante network.
  2. Disconnect and reconnect the device.
  3. Wait for at least 2 minutes.
  4. Use the ‘Forgot PIN’ option in the Unlock Device panel.

How to Isolate a Device from the Rest of the Dante Network

There are 3 ways to isolate a device from the rest of the network.

Option 1: Remove all other Dante devices from the Dante network

You can isolate a device by physically disconnecting all other Dante devices from the network switch, or by completely powering down all other devices, leaving on the network only the locked device and the computer running Dante Controller.

Note:  Dante Virtual Soundcard and Dante Via are considered to be Dante devices – all running instances of those applications must be fully stopped, even if they are on the same computer on which you are running Dante Controller.

Option 2: Connect your Dante Controller computer directly to the device

Physically remove the device from the main Dante network switch, and either connect it directly to your Dante Controller computer (using a normal Ethernet cable), or connect the device and your computer to a separate network switch (to which there are no other Dante devices connected).

Option 3: Use a VLAN

Set up a Virtual Local Area Network  on which there are only the locked device, and the Dante Controller computer.

Resetting the PIN for a Locked, Isolated Device

Once you have isolated the locked device, disconnected and reconnected it, and then waited for at least 2 minutes:

  1. Open the Unlock Device panel for the device (See Unlocking a Dante Device).
  2. Click the ‘Forgot PIN’ option.
  3. Click Reset.

The device is now unlocked, and can be re-locked using a new PIN if required.

Subscriptions from Unlocked Devices to Locked Devices

If there are existing subscriptions to a device when it is locked, those subscriptions will continue to function as normal.

They can also be removed, and replaced (assuming the subscribing device is unlocked).

No new subscriptions can be made to a locked transmitter. The 'Access control' tooltips are associated with attempted subscriptions to locked transmitters.

Note:  If you attempt to subscribe a legacy (pre-v3.10 firmware) receiver to a locked transmitter, subscription status icons for any existing subscriptions (made before the device was locked) may change to indicate an error state. However, audio will continue to flow for those subscriptions. To reset the subscription icons: Remove all subscriptions, and reinstate the original subscriptions only.

Locking Devices with Residual Connections

Occasionally, a transmitter will have residual unused connections (transmitting but unsubscribed channels) from a previous subscription state, which need to be closed before the device is locked. This can cause an interruption to media from that device.

When you attempt to lock a device and residual connections are detected, Dante Controller presents a warning dialog:

Click Ok to proceed or Cancel to abort the lock process.

While the residual connections are being closed, Dante Controller displays a progress dialog:

When the preparation process is finished, the standard Lock Device dialog is presented, and the device can be locked as normal.
