HelixNet System Hosts
Arcadia: Supports up to 128 HelixNet User Stations over Ethernet or Powerline via the HXII-DPL Powerline Device. Up to 24 Channels can be HelixNet Enabled using a Licensed Port for assignment to any HelixNet User Station keyset.
HMS-4X: Supports up to 64 endpoints (Remote Stations, Speaker Stations, Beltpacks, HLI-2W2, HLI-4W2, LQ port). User stations can connect directly to the 2 HMS-4X Powerlines or via optional HLI-ET2 module using HXII-DPL Powerline Device or 3rd party network switch connection. HMS allows use of 12 channels which can be expanded to 24 using optional license.
