When several RAVENNA devices are present on the same network, one is elected as PTP Master, and the other ones as PTP Slave.
Only the PTP Master is able to lock to an external reference (i.e. Wordclock).
If the PTP Master device fails, one of the Slave device will be elected to Master, but by default will be on its internal clock.
The PTP priority has to be configured on the Slave device, to have it set on the external clock in the case it becomes Master.

Setup example :

- Horus 1 master with sync on WC
- Horus 2 slave, but fallback as master with sync on WC

Prerequisite

Your Merging RAVENNA device must be running firmware XXXX or above.

 

  1. Open the advanced pages of the slave device, and go in the PTP tab.
  2. Tick the "Manual" box and set "Priority 1" to 120 (Default value 127).
