Other transient clock states exist, which are not listed above.
AES67 Status
Indicates the state of the PTPv2 clock for AES67-enabled devices. Possible states are identical to those
of Primary and Secondary Status.
Preferred Master
Raises the priority of the device in the master clock election.
If only one device on a particular clock domain has this checkbox ticked, it ensures that the selected
device becomes master clock (for that clock domain). When multiple devices have their Preferred Master
checkbox ticked, the master will be elected automatically from within that group.
If 'Slave Only' is shown instead of a checkbox, it indicates that the device is not capable of acting as a
master clock.
Enable Sync To External
Forces the Dante module to derive its clock from an external source - either from a host device word clock,
or from an auxiliary device.
This will also ensure that this Dante device becomes master clock for the relevant clock domain (unless
another device has 'Preferred Master' selected). It is not normal practice to configure more than one device
per clock domain with an external clock source. In this case, the user is assumed to have synchronized
external word clock sources (e.g. house clock).
Where the checkbox is present but greyed-out (and inactive), it means that the Dante device can be slaved
to an external word clock, but it cannot be set directly from Dante Controller - it must be done via the host
device user interface, or via some other method (e.g. third-party control software). If the checkbox is
greyed out and populated, it means that the Dante device is currently slaved to the external clock.
If N/A is displayed, it means that the device does not support slaving to an external word clock.
Note: If no clock status information is displayed for a particular device, it can indicate a ConMon
(Dante control and monitoring service) failure on the device. The device may need to be reset or
restored.
About Clock Domains
Dante Devices that are not configured with sample rate pull-up/down operate on the default clock domain,
using the default clock. Devices that are configured with sample rate pull-up/down operate on separate
'clock domains', which have their own dedicated PTP clocks, adjusted to account for the pulled up/down
sample rates.
Clock domains are not physically separated, they all exist on the network simultaneously. Devices with
pull-up/down synchronize to the appropriate clock for their pull-up/down setting, and ignore other clocks.
Those devices are shown with the relevant pull-up/down value against their Clock Status in the Clock
Status tab.
Dante devices can only transmit audio to, and receive audio from other devices on the same clock domain.
For example, a device with zero sample rate pull-up/down operates on the default clock domain, and
cannot transmit audio to, or receive audio from any devices on the +4.1667% clock domain, or the -1%
clock domain, etc.
Up to 5 separate clock domains can be supported at any one time. All clock domains have their own
master clock.
