The sender details list the outgoing streams from the converter and the labels correspond to
the labels in the output labels tab.
PTP Clock Settings
The PTP settings let you configure the settings for the PTP grandmaster.
When connecting Blackmagic 2110 IP Converters to a 10G network switch with a PTP
grandmaster, the converter needs to be set to 'PTP follower only' mode to prevent a timing
conflict. If two Blackmagic IP converters are connected directly, set one to be the follower by
ticking the checkbox.
Domain Number
Enter the domain number to match that of the PTP grandmaster. This is commonly 127 but can
be changed by entering a different domain number in the field.
Master
The master address field display the MAC address of the PTP grandmaster. This is either a
separate grandmaster device, or a Blackmagic 2110 converter.
PTP Lock
The PTP lock field will acknowledge when the converter is locked to a PTP clock via Ethernet.
Priority
Priority 1 and 2 settings let you set the preferred PTP grandmaster available when there is more
than one PTP grandmaster on the network. The lower the number suggests the higher priority.
Announce Interval and Timeout
The announce interval and timeout fields need to match the specifications of the PTP
grandmaster which transmits sync messages typically every two seconds or 2000 ms. To
change the frequency of the message use the menu to select a different time. The ranges
available for announce interval and announce timeout will depend on your PTP grandmaster.
