Clear-com HLI-2W2 Interface Module for HMS-4X Main
Station
Clear-com The HelixNet HLI-2W2 is a dual 2-wire
interface module for the HMS-4X** main station.
Interfacing
HLI-2W2’s 2-wire analog partyline interface are
assignable to any channel in the HelixNet system and provide connectivity to
powered Clear-Com or RTS-TW analog partyline systems. Level control and
VOX/Gate capability is provided for each interface to accommodate the
connected system.
HLI-2W2 include call signaling and remote mic kill
circuits when used with compatible Clear-Com and RTS-TW partyline devices.
Local and Central Management Options
HLI-2W2 can be added to any HMS-4X** main station
with an available option slot. Once installed, any channel can be
independently assigned to either 2-wire port locally on the HMS-4X front
panel or centrally from the Core Configuration Manager™ (CCM*).
