Connecting Yamaha Dante devices with AES67
7
 Many non-Dante AES67 devices support PTP v2 only
PTP v1 and v2 are not inter-compatible. One AES67-enabled Dante device will act as the
boundary clock between PTP v1 and v2, bridging the two clock domains (i.e. Dante and the
other).
Dante and PTP v2 use different methods for electing the Master device. So when using
the two in combination, care needs to be taken. Devices that support PTP v2 have many
different priority levels available for becoming the Master device. Dante takes care of this
automatically, while other PTP v2 devices may be configured manually. Select the most
appropriate strategy for clock distribution, and follow these basic guidelines below.
A. An AES67-enabled Dante device is Master for both Dante and AES67.
1) Enable the device’s “Preferred Master” status
2) Disable “Preferred Master” for all Dante devices that have AES67 disabled.
3) Disable “Sync to External” for all devices.
4) Assign a PTP v2 priority level of between 128 and 255 for all non-Dante
devices.
B. A non-Dante PTP v2 device is the Master. This could be a Grandmaster Clock
device, or a network switch, or another AES67 device.
1) Make sure the PTP v2 Master has a priority of between 1 and 100, and is
using the “Media Profile” clock settings.
2) Disable “Preferred Master” and “Sync To External” for all Dante devices.
