Page 48: Multicasts - Streams
When the Edit button is clicked it is possible to define the following multicast parameters (note that some parameters are only relevant and selectable when the probe is equipped with the correct options): VB440 Studio Probe User’s Manual v6.0 © Bridge Technologies Co AS... - Page 49 Name: A name should be assigned to each unicast/multicast. The name will be used throughout the VB440 user interface when referring to this stream. It may also be used by an external management system like the VBC Controller. To add copy of one stream for use with 2022-7, give the two streams the same name, but add a different class to them.
- Page 50 If a zero source address is specified for a multicast it will be joined without a source. This allows both source specific multicasts and non-source specific multicasts to co-exist in the same network and be joined by the VB440. SSM source 2: Additional SSM source addresses may be specified to enable back-up solutions.

Note that the Ethernet setup parameters (IP address, netmask and gateway) and probe name and location are not part of the XML document. Hence exporting the full configuration of one VB440 Studio Probe and restoring it on another will make the two VB440 Studio Probes identical except for the network settings. -

The VB440 always acts as a slave clock only, and it will not show other slave clocks. The clocks shown will be clocks which present themselves as master clocks, this includes boundary clocks. - Page 56 Priority1 indicates the VB440s own internal Priority1. Please note that this means the VB440 will never synchronize to a clock with a higher value in the Priority1 field (Lower priority) than its own.
- Page 57 “1” will be selected as the master without any further comparison in the following steps. This means that that clock will be acting as master as long as it is online, even if it loses sync. VB440 Studio Probe User’s Manual v6.0 © Bridge Technologies Co AS...
