Technical Specifications

HelixNet System Hosts
Arcadia: Supports up to 64 HelixNet endpoints (HRM-4X, HKB-2X & HXII-BP) over Ethernet. Up to 24 Channels can be HelixNet Enabled using a Licensed Port for assignment to any HelixNet endpoints keyset.

HMS-4X: Supports up to 64 endpoints (HRM-4X, HKB-2X, HBP-2X, HXII-BP, HLI-2W2, HLI-4W2, LQ port). User stations can connect via HMS’s 2 Powerlines (see datasheet for limits) or over Ethernet via optional HLI-ET2 module. HMS allows use of 12 channels which can be expanded to 24 using optional license.
