SPECIFICATIONS:
Linking
HMS is required as the HelixNet Master. Link Group may include five additional HMS Members, including up to three LQ devices for a maximum of six HMS/LQ in Link Group. HMS link using HLI-ET2 or HLI-FBS modules over LAN/WAN connections. Link Group supports up to 64 endpoints (station/port).
Channels
System provides 12 or 24 intercom channels assignable to any user station or port in the system. Four Channels can be assigned to station. Program Audio can be associated with any channel with independent endpoint level control.
Roles
99 Roles for naming and dynamic configuration of user station settings. Role can be applied to multiple user stations.
