HMS-4X Main Station Rear Panel: Interface Modules

Up to three Interface modules (of the same or different types) can be fitted to the extension bay of the Main Station. When looking at the rear of the Main Station, expansion slot 1 is the left-hand slot, expansion slot 2 is the middle slot, and expansion slot 3 is the right-hand slot.

Warning: The interface modules are NOT hot pluggable. Ensure that the Main Station is powered down before inserting or removing modules.

Description

Two-wire interface module (HLI-2W2)

 

This is a two Channel, 2-wire device that enables interoperability with, CellCom® / FreeSpeak®, and HME DX systems, as well as both Clear-Com and RTS analog Partyline systems.

Note: This module requires a powered analog Partyline.

The module provides two analog Partyline connectors (3 pin female XLR connectors) with the following pin out:

Use HelixNet Main Station menus to set the module for either RTS or Clear-Com systems. If RTS mode is selected, you can set either:

  • Pin 2 for power to mixed audio Channel (1 – 24)

  • Pin 3 for power to mixed audio Channel (1 – 24)

  • Select either pin and assign required Channel to it.

Four-wire interface module (HLI-4W2)

 

This is a two Channel, 4-wire device that enables interoperability with the Eclipse® digital matrix system and other four-wire audio sources such as telephone hybrids, AB-120/-100, PA (Public Address) / SA (Stage Announce) systems. The module also enables HelixNet-to-HelixNet connections using four-wire audio ports. Two four-wire connectors (etherCON type RJ45 socket) are provided with the following pin out:

Warning: Both ports are configured to bridge traffic from one port to the other in order to work in a daisy-chained configuration. Spanning Tree Protocol is not enabled on these ports, therefore do not connect them both to the same network.

 

Fiber interface module (HLI-FBS)

Enables linking of Main Stations. Contains two SFP cage slots. The module is supplied with one transceiver fitted.

Any 100BASE-X SFP can be connected.

An LED at the side of each connector flashes green when there is network activity.
