n A green light indicates that the device is currently synced to (or is driving) the network clock
n A red light indicates that the device is not currently synced
Mute
Indicates the mute status for the device.
n A red mute icon indicates that the device is currently muted (usually due to loss of clock sync)
n No icon in the mute column means that the device is not muted (audio should be flowing normally)
Clock Source
Indicates the clock source for the device.
n Dante: The device is deriving its clock from the Dante network, or is acting as master clock (but not
deriving its clock from an external source)
n External: The device is deriving its clock from an external word clock source
Primary Status | Secondary Status
Indicates the state of the PTP clock for the primary and secondary network interfaces.
n Master: Device is the current PTP Master Clock on the primary Dante network
n Slave: Device is a PTP Slave on the primary Dante network
n Passive: Device is not using clock synchronization information from this interface
n Link Down: The interface is not connected to the network
n N/A: Indicates that the device does not support clock status reporting. In the Secondary Status
column, can also indicate that the device is non-redundant.
n Listening: Usually transient. When persistent, it indicates that the device can not operate as a clock
master (slave only), and is waiting for a clock master to appear on the network.
Devices that are configured with sample rate pull-up/down are shown with the relevant pull-up/down value
against their Clock Status. For example, a device acting as master clock with +0.1% pull-up will be shown
as Master (+0.1%). See
About Clock Domains for more information.
Other transient clock states exist, which are not listed above.
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).
