The Link-Master role
The Link-Master role serves three main purposes:
1. It facilitates Link-Group membership.
2. It is the owner of Channel names, meaning that Channel names will only persist
(be maintained consistently) if the Link-Master is operational.
3. It is responsible for the synchronization and distribution of both configuration
and device availability status throughout the Link-Group.
Note: The Link-Master must be reachable on TCP port 80 and TCP/UDP port 655 by all
devices within the Link-Group.
Note: It is recommended that the IP address of the Link-Master is allocated statically.
When allocated by DHCP the IP address can change. If this happens the LQ devices
will no longer be able to reach the Link-Master device.
Note: Any device can be set to Link-Master mode. Link-Master mode is the factory default
setting.
