Clocking
Unicast Delay Requests
Delay requests are messages sent by clock followers to the clock leader to establish the time it takes for
data to traverse the network between the devices. By default, delay requests are multicast messages, and
in networks with lots of devices, they can add up. Enabling 'Unicast Delay Requests' forces clock
follower devices to send delay requests to the clock leader using unicast instead, which reduces
multicast traffic.
Note:
Unicast Delay Requests does not have to be enabled on the clock leader, only on the clock followers.
Important:
Some older Dante devices do not support Unicast Delay Requests. Before enabling the
feature for your clock followers, check that your current clock leader supports the feature, by
attempting to enable it for the device. If the clock leader device does not support unicast delay
requests, do not enable it on your clock followers (it may prevent your devices from synchronizing).
You can however choose an alternative clock leader that does support it, and then enable it for the
clock followers that also support it.
Device Latency
Shows the current device latency setting and allows you to change the operating receive latency for the
selected device. Select a value and click OK to apply the latency to all flows that the device is receiving.
Applies to audio channels only.
Note:
The 150 µsec setting is unavailable for devices that include an internal network switch.
Note:
Device latency cannot be configured for Dante Via devices.
Note:
Devices enrolled in a Dante domain may support extra latency values.
Warning:
Changing the latency value will cause disruption in the audio while the flows are
reestablishing the new latency setting.
Reset Device
Allows you to remotely reboot the Dante interface, and to reapply factory settings (Factory Reset).
Rebooting the Dante device may also require a reset of the host audio equipment containing the device.
Factory Reset wipes the following device configuration settings:
■
User-defined device name
■
User-defined channel names
■
Clock configuration (clock leader / external clock leader setting)
■
Static IP addresses
■
Redundancy configuration
■
Sample rate setting (including pull-up/down)
■
Latency setting
■
Any existing audio routes
Supported devices allow you to 'Clear Config' instead of Factory Reset. Clear Config wipes the same
configuration settings listed above, but allows you to optionally keep the IP settings (i.e., retain the Dante
Redundancy settings, and any static IP addresses currently configured in the Network Config tab).
