He l ix N e t ® Ne tw ork Partyl ine Int er com Syst em HMS-4X Main Station HMS-4X The HMS-4X is a 1RU digital partyline main station that provides power and up to 12 networked channels of audio to support up to 20 digital beltpacks on a single shielded twisted-pair cable. Key Features And Benefits • Up to 3 Main Stations can be linked over LAN • Up to 12 networked channels of audio Description The HMS-4X is a 1RU digital partyline main station that offers 4 channels of full-duplex audio and program audio feed that can support up to 20 beltpacks on a single station. The HMS-4X has high channel density, offering up to 12 networked intercom channels and power for beltpacks transmitted over a single shielded twisted-pair cable (mic, CAT5 or CAT6 cables). The system is designed to operate on a facility’s existing cabling structure so that no additional cable runs are needed. The front panel HMS-4X has easily accessible separate headset and mic buttons, a speaker with a rotary knob to control listen volume levels, multi-color LED levels, a Stage Announce button Remote Mic Kill button and an All Talk button. Plug-and-go installation, quick access to system settings, simple cable operations and fast update capabilities make the HMS-4X easy to use. Seamless Linking Using single shielded twisted-pair cabling infrastructures, up to three HMS-4X Main Stations can be linked together without the need for active splitter devices. Linked stations are automatically detected and configured so that any beltpack has access to any two of the available active intercom channels. In addition, audio and control data is embedded onto each of the powered circuits throughout the system. Redundant connections between systems are possible with a returned cable on the end of a daisy-chain. Administrators of the system can lock or unlock parameters for users via the main station’s Administration menu. Optional Modules Each HMS-4X has three rear-panel interface module slots for a combination of any four available modules: Ethernet, Fiber, 4-Wire and 2-Wire. The Ethernet module (HLI-ET2) provides a dual LAN interface to connect multiple HMS-4X Main Stations or can connect Remote Stations (HRM-4X) and Speakers Stations (HKB-2X) via Ethernet. The Fiber module (HLI-FBS) provides a daily-chain fiber interface connection to other HMS-4X Main Stations. The 4-Wire module (HLI4W2) provides an easy way to interface common 4-wire audio paths. The 2-Wire module (HLI-2W2) provides connection between Clear-Com or RTS intercom to the HMS-4X Main Stations. • Up to 20 beltpacks supported on one main station • Large format yellow OLED, 10-character label displays • Plug-and-go installation with hardware auto-discovery • Line status indication • Rotary channel level controls • USB-A and USB Micro-AB ports • Built-in expansion slots for optional interface modules • Interface modules available: Ethernet, fiber, 2-wire and 4-wire • Program input • Speaker and Program level controls • GPIO-DB-25 (4 relays and 4 opto inputs) • Remote mic kill HMS-4X Main Station Rear Panel 1.
