Technical Guide | HelixNet IP Network Guidance Page 8
It should be noted that HelixNet reserves the 10.0.0.0/16 network for connecting
HelixNet devices by powerline – placing HelixNet devices/systems on 10.x network may
cause issues.
Firewall:
TCP/UDP
IP Ports
To support remote connectivity of HelixNet endpoints external to a LAN or WAN, port
forwarding rules will be needed to achieve the required connectivity to the HMS that
has been set into Link-Master mode. Listed below is the Port # and a description of what
the opened port provides access to.
- Port 6001 TCP - Pairing with HKB-2X, HRM-4X, HXII-BP, Authenticate, update,
and reboot
- Port 6001 UDP - Audio
- Port 80 HTML – Core Configuration Manager (not recommended as
management of the system should be limited to a device within the secured
network)
Link-
Master
Mode
To create a Link-Group, you must designate one unit as Link-Master in the Core
Configuration Manager (CCM). The Core Configuration Manager (CCM) interface
provides an intuitive software utility for HelixNet on any browser-enabled platform. The
CCM facilitates a quick and simple means of configuring any devices in a Link-Group,
including role-based configuration of endpoints, save and restore, and live monitoring
of all system components.
The Link-Master designation serves three main purposes:
- It facilitates Link-Group membership.
- It is the owner of configured Role information, meaning that Roles will only
persist (be maintained consistently) if the Link-Master is operational.
- It is responsible for the synchronization and distribution of both configuration
(Roles) and device availability status throughout the Link-Group.
Note: Clear-Com recommends that the IP address of the Link-Master is allocated
statically. When allocated by DHCP, the IP address can change. If this happens the Link-
Members will no longer be able to reach the Link-Master device, and Role information
may not be available.
Note: Any device can be set to Link-Master or Link-Member. The default setting for
HelixNet linking mode is Link Disabled.
HelixNet devices that are not identified as master will have the designation of Link-
Member. Joining a device to a Link-Group requires that device to be set to Link-Member
which will prompt the user to enter the IP address of the Link-Master. Once joined to
the Link-Group, all devices attempt to connect to all other devices within the group.
