1 Introduction

This guide is intended to help you install, configure, and use the HelixNet Partyline™ system.
HelixNet Partyline is a digital intercom system designed to combine the simplicity and ease of use
of an analog partyline system with the quality and deployment flexibility of Ethernet networks.

1.1 Simple installation

User stations can be added to the system without configuration
l Simple and fast global web browser or front panel configuration
l All partyline channels are available on every cable
l Easy integration with other 2-wire or 4-wire systems
l Standard Infrastructure:
HelixNet | User Guide
l Ethernet networks – PoE powered user stations
l XLR Cables – daisy changing and passively splitting
l Digital distribution for low noise floor
Note: Cabling for a HelixNet system should always be screened.

1.2 System scalability

HelixNet Partyline is easily expanded by adding additional HMS-4Xs (up to a maximum of 6) or LQ
devices (up to 3 in a Link-Group).
l 12 or 24 channels per system with optional feature license
l 64 Endpoints (user stations and ports) per HelixNet system
l LQ devices can be mixed in a HelixNet Link-Group for audio port expansion as well as the
optionally licensed Agent-IC mobile app and SIP/VoIP clients.
l Expansion option to enable talk and listen on more than four Channels.
l A choice of beltpacks and the option of wall/desktop Remote Stations that connect to a
system that contains a Main Station

1.3 Important Safety instructions

HelixNet digital Partyline uses cable infrastructure to transport audio and data over a range of
frequencies. The maximum frequency used for transmission is approximately 25MHz. Depending
Page 8
Page 9
HelixNet | User Guide
on the amount of audio and data transmitted, HelixNet digital Partyline can work with as much as
90dB signal attenuation. However, the receivers are very sensitive and are susceptible to
crosstalk between cables.
Therefore it is important to maintain cable shield integrity through all connectors,
splitter boxes and patch panels.
Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two
blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If
the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete
outlet.
Protect the power cord from being walked on or pinched particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.
Only use attachments/accessories specified by the manufacturer.
Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with
the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to
avoid injury from tip-over.
Unplug this apparatus during lightning storms or when unused for long periods of time.
Refer all servicing to qualified service personnel. Servicing is required when the apparatus has
been damaged in any way, such as power-cord supply or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture,
does not operate normally, or has been dropped.
Warning: To reduce the risk of fire or electric shock, do not expose this product to rain or moisture.
1.3.1 Safety symbols
Familiarize yourself with the safety symbols in the diagram below.
These symbols are displayed on the apparatus and warn you of the potential danger of electric
shock if the system is used improperly.

HelixNet | User Guide
Note: For compliance purposes see Compliance.

1.4 Methods of connection: system overview

HelixNet devices can be connected in several different ways. A combination of these methods can
be used.
1.4.1 Connecting by cable (Powerline)
Page 10
Page 11
In this scenario devices are connected by cable in either a daisy chain or home run fashion. Power
and data are passed down this connection in what is known as a powerline.
See Linking Remote Stations and Speaker Stations for detail on different types of device layout
(topologies).
Up to 20 beltpacks can be connected to one Main Station, and Remote and Speaker Stations can
be included in the powerline.
However, including Remote and Speaker Stations in the powerline will affect the amount of
devices that can be connected, as Main and Remote Stations draw more power than beltpacks.
You can find the URL to an online powerline/distance calculator at the beginning of Installing
HelixNet Partyline
1.4.2 Pairing by LAN
HelixNet | User Guide
Page 11
When pairing by LAN, devices are connected to the same network by Ethernet cable (RJ45) and
then paired from the device menus.
See Ethernet point-to-point link for more detail.
Note: Pairing by LAN offers better latency than connecting with cable.
Page 12
1.4.3 Connecting more than one Main Station (Linking)
HelixNet | User Guide
Page 12
Up to six Main Stations can be linked. In earlier versions of HelixNet (2.0 and below) linking Main
Stations was a way of expanding the Channel capacity of your system (4 Channels on each Main
Station). In HelixNet 3.0 and later, this is no longer necessary as each Main Station already has 12
Channels, with the option of licensing another 12 (24 Channels in total). A system, regardless of
the number of linked HMS units, will have 12 Channels by default with the potential of increasing
that number to 24 with the purchase of a license for each HMS within the Link-Group.
Linking Main Stations in HelixNet has the following benefits:
l More beltpack connections (20 per Main Station)
l System distribution as far as your LAN allows.
l The ability to configure all devices from an Internet browser using the CCM (Core
Configuration Manager).
l Using a role-based setup.
l Expanding a Main Station from four keys to 24 key using the expansion key mode.
Page 13
HelixNet | User Guide
Main Stations can be linked using different methods:
By Ethernet and RJ45 cable in your LAN. See Linking Main Stations (cabling and linking from
device menus).
By fiber cabling between units.
1.4.4 Key Expansion Groups (Main Stations and Remote Stations)
Page 13
Devices can be set up as a key Expansion Group to allow convenient control of audio from one
device, and to increase the “key” capacity so that a user can view and control more than 4 keys (up
to 24 with 5 expansion panels).
See Setting up a key Expansion Group for detail.
Page 14

1.5 System Resource

System Resource Units (up to 70)
Color Indication Units
Green ≤ 59 Within system limits
Amber 60 - 63 Approaching limits
Red ≥ 64 Exceeding limits
A HelixNet system/Link Group will support up to 64 endpoints.
Endpoints consume system resources depending on the number of audio paths the endpoint
contains and may include: user stations, assigned interface ports, program audio inputs, LQ,
Agent-IC and SIP accounts.
Exceeding the system endpoint limits will cause a sluggish system response.
1.5.1 Conserving system resource
In larger systems it is recommended to balance the loading of endpoints on the HMS-4X Main
Stations in the Link Group. LQ interface ports and LQ Agent-IC, IVC and SIP accounts load the
resources of the system's Link Master.
HRM-4X Remote Stations include multiple audio interfaces which can be assigned to the system's
channels. When assigned to channels, these use resources. The Remote Station allows you to
disable the unit's program audio input as well as to configure the stage announce output for local
use. In this way you can conserve system resources in larger systems.
HelixNet | User Guide
1.5.2 System resource meter
There is a resource meter on the main station device icon. This is found in the Overview page of
the CCM. Hover your mouse over this icon to see how many system resource units are in use.

3 Installing HelixNet Partyline

This section describes how to install your HelixNet Partyline system. It also provides basic
guidance on planning your installation.
For related information, see Cabling reference and the Online Powerline cable distance calculator
at:
https://clearcom.com/DownloadCenter/technicaldocs/HelixNetCablingCalculator/index.html#/
Tip: For guidance on connecting HelixNet Partyline to other systems, using the optional interface
modules, see Connecting to Other Intercom Systems.
Do not plug any non-approved equipment into HelixNet Partyline.
HelixNet Partyline operates at different voltage levels than analog two-wire Partyline systems.
Do not plug any analog two-wire Partyline equipment into the HelixNet Partyline ports, as this
may cause damage.

Partyline Channel 4
Program Feed
Note: The program is always a participant within a Channel and cannot exist outside
of a Channel.
In a traditional analog Partyline system, one cable is dedicated to each Partyline
Channel. This can make it more difficult to build redundancy or spare capacity into the
installation (owing to the number of connectors / cables dedicated to the delivery of
Channels).
In the HelixNet system, one cable can carry multiple Channels. Because one cable
can carry all Channels, the second connector for each line can either be used for
redundancy (flybacks) or for future extensions / changes to the cabling topology
(layout).
Example analog Partyline devices including RS-701 beltpacks. Analog beltpacks must
be re-cabled to use alternative Channels, requiring the physical re-location of cabling
for new configurations.
Page 53
To aid switching, Clear-Com sells additional switching equipment (the SB-704 and
RCS-2700 devices). The RS-702 (6-pin XLR) beltpack requires the YC-36 splitter /
combiner to combine 2 Channels into a 6-pin configuration, and multi-conductor
cables.
The RS-703 (3-pin XLR) beltpack requires a TWC-701 device to combine 2 Clear-
Page 54
Key to analog and digital cabling comparison diagram
Com Channels in a single twisted pair.
Example digital Partyline devices including beltpacks. Digital beltpacks can support
any of the Partyline Channels (plus Program Feed) whenever they are physically
located on the system.
New configurations of beltpacks and Channels can be deployed without the physical
relocation of assets.
Note: The capabilities of different cable types may impact how far away beltpacks can be
placed from the Main Station, and the topologies you use. For more information about
cabling, see Cabling reference.
3.1.2 Topologies
HelixNet Partyline can be deployed using a wide range of topologies, both complex and
straightforward. The following table describes three standard types of topology:
HelixNet | User Guide
Topology Description
Daisy-
chain
Star In a star topology, the Main Station is connected to a passive (Y) splitter such as an
Tree A tree topology is a more complex version of the star topology, using serially
In a daisy-chain topology, the Main Station is connected to the first unit. The units are
then connected in a series, using the pass-through connector on the back / rear of the
device to pass on the connection. No termination is required. HXII-BP-X4 beltpacks
require a passive Y splitter for daisy chaining.
Daisy-chains can be either linear or loop back to the Main Station to form a ring for
redundancy.

Key to example system topologies (layouts) diagram
Feature Description
HMS-4X Main Station (digital Main Station) (rear panel).
There are two lines (digital Partylines) on the Main Station, each of which can support
up to 10 digital beltpacks. There are two connectors (3-pin XLR, male and female) for
each line.
Daisy chained beltpacks. To create a ‘daisy chain’ of connected beltpacks:
Connect the first beltpack to the Main Station, using either of the 3-pin XLR
connectors (female or male) on the base of the beltpack.
Pass on the connection to the second beltpack, using the remaining connector as the
pass through.
Repeat for all beltpacks (up to 10) in the chain. No cable termination is required.
Note: For the HXII-BP-X4 beltpacks, you must use a passive Y splitter.
You can locally power an HRM or HKB within a daisy chain. This prevents the normal
draw off the powerline by the locally powered device.
Page 55

Key to example system topologies (layouts) diagram
The second layout uses an XLR Bulkhead and a Mult-box (passive (Y) splitters) to
combine:
A daisy chain (with optional redundancy flyback).
Point-to-point connected beltpacks (using the Mult-box).
The XLR Bulkhead and splitters should be screened.
The complexity and variety of layouts does not restrict physical access to Channels.
Because HelixNet Partyline is a digital system, the HelixNet Stations can access any
of the available Channels (plus a Program Feed), however they are connected to the
Main Station, see diagram in Comparing digital with analog cabling.

Install to a shelf or other flat surface.
Mount on a table or other flat surface.
For more information, see HXII-BP-X4 Beltpack (beltloops and clip).
3.5.1 Power Up
The HXII-BP-X4 Beltpack is powered from:
The standard microphone cable that connects the device with the HMS-4X Main Station (see
below).
Power over Ethernet (PoE) using a cat5, 5e or 6 cable.
Notes: To use PoE, you must connect a third-party PoE switch between the Main Station and
the HXII-BP-X4 Beltpack.
HelixNet | User Guide
You can power the HXII-BP-X4 over both microphone cable and PoE. In this case, the
PoE takes priority. After the beltpack boots up, you cannot switch between PoE and
powerline (microphone cable) mode.
3.5.2 Connecting the HXII-BP-X4 Beltpack over Powerline to the Main Station
To connect the HXII-BP-X4 Beltpack to the Main Station:
1. There are two powerline connections on the Main Station which can each support up to 10
digital HXII-BP-X4 Beltpacks. There are two connectors (3-pin XLR, male and female) for
each line.
Connect the cable to the selected connector on the Main Station.
Note: For the location of Lines 1 and 2 (the powerlines) on the Main Station, see F,
G in diagram in (HMS-4X Main Station: rear panel.
2. Connect the cable to the beltpack, using the 3-pin XLR connector on the base / rear of the
beltpack.
For examples of topologies, see Topologies
3.5.3 Powering the HXII-BP-X4 using PoE
To connect the HXII-BP-X4 to the Main Station for PoE:
1. Connect the Main Station to a network switch using the HLI-ET2 Ethernet interface module.
Page 61
Page 62
2. Connect the HXII-BP-X4 Beltpack to the PoE switch on the same network as the Main
Station.
Note: The beltpack must be paired to the Main Station.
Important: When using an IEEE-802.3af compliant PoE switch, be sure to note the
switch's power budget. Each HXII-BP-X4 requires 4 Watts of power. Do not exceed
the power budget of the switch when attaching HXII-BP-X4 beltpacks.

3.6 HelixNet Infrastructure

This section contains guidelines for using HelixNet infrastructure components including cables,
connectors, splitter boxes and patch panels. HelixNet digital Partyline uses cable infrastructure to
transport audio and data over a range of frequencies. The maximum frequency used for
transmission is approximately 25MHz. Depending on the amount of audio and data transmitted,
HelixNet digital Partyline can work with as much as 90dB signal attenuation. However, the
receivers are very sensitive and are susceptible to crosstalk between cables.
HelixNet | User Guide
Therefore it is important to maintain cable shield integrity through all connectors,
splitter boxes and patch panels.
The symptoms of crosstalk are:
l Main Station front panel LINE LED indicator turns amber or red
l Beltpacks, Remote Stations and Speaker Stations take longer than usual to boot and
connect.
l Beltpack, Remote Station and Speaker Station front panel signal strength indicators show
lower than usual signal strength (zero or one bar).
l Main Station diagnostics screen (Diagnostics->Powerlines) indicates collisions or errors
on the line.
3.6.1 Cables and Connectors
Clear-Com recommends the following shielded cables:
Microphone cables
Belden 9207 and 9463F with the two main conductors connected to XLR pin 2 and 3 and the drain
wire to pin 1.
Page 62
Cat cables
Belden 1351A or 1533P with the following connections at the XLR connector:
Page 63
HelixNet | User Guide
Cat5/5e/6 XLR
White/Orange 1
Orange 1
White/Green 3
Blue 2
White/Blue 3
Green 2
White/Brown 3
Brown 2
Shield/Drain 1
It is important to connect the cable shield or drain wire to the XLR pin 1 to maintain the
shield integrity throughout the cable and connector.
Note: The total amount of cable deployed for a digital intercom line contributes to the total
capacitance of the line, even though some cables might not have a beltpack connected at
the other end. The more capacitance there is, the more attenuation there will be. Clear-
Com recommends that you use the minimum amount of cable. For example, daisy-chain
or split a cable at the far end, close to the beltpacks, rather than make two home runs to a
central patch panel.
3.6.2 Patch Panels
Clear-Com recommends XLR patch panels. These should be made of 3 pin XLR feed-through
adapters (for example, Neutrik NA3MDF) that maintain shield integrity from the back to the front.
These adapters also enable easier rewiring of the back or the front of the panel.
3.6.3 Splitter Boxes
Ensure that you split the digital intercom lines within a shielded enclosure. For example, a 1RU
shielded chassis, such as Middle Atlantic CH1, and daisy-chained XLR connectors (for example,
Neutrik NC3MD or NC3FD).
To prevent crosstalk between lines, ensure that each shielded splitter box contains only one digital
intercom line. If you have to split more than one digital intercom line, use multiple shielded
enclosures.
Page 63
Page 64
For more information on cabling see Cable connections.

3.7 Converting Analogue Partylines to HelixNet

HelixNet | User Guide
Many Partyline installations use daisy-chained power terminal blocks to passively split analog
Partylines. This way of splitting works relatively well for one HelixNet Main Station. But because
the cable shielding through those blocks is not maintained, it makes the communication much
more sensitive to interference.
Also, crosstalk occurs if two or more Main Stations use terminal blocks that are close to each
other.
To maintain shield integrity, Clear-Com recommends that you:
Place existing terminal blocks in shielded and grounded enclosures
Or
Replace the terminal blocks with shielded and grounded XLR splitter boxes and XLR patch
panels.
Page 64

4 IP Network Structure

Connecting into an existing IP network requires planning with your IT department in order to plan
the IP addressing scheme. By default, HelixNet Main Station uses automatic IP addressing
(DHCP) enabled. In order for that to work properly in an existing IP network there must be a
DHCP server handing out IP addresses. If no DHCP server is found, a Main Station will revert to
an unused link-local address in the 169.254.0.0/16 block. (See Link Local Environments for more
information).
Through the Networking menu on the devices, you can disable DHCP and set static IP addresses.
For HelixNet 3.0 and above, it is not necessary for Main Stations or Remote Stations to be on the
same Subnet, the devices will link across your LAN.
HelixNet | User Guide

4.1 Multiple Groups in the Same IP Network

You can link six Main Stations together to form a Link Group. You must select one of the Main
Stations to be a Link Master. You can have multiple groups in the same network by having multiple
Link-Masters. Each Link-Master heads a group of Main Stations, and does not interfere with other
groups.
Page 65
Page 66
HelixNet | User Guide
Specification Value
Latency on Powerline 40-80ms (Depends on cable type and length, and how
many devices are connected. The greater the number of
devices, the greater the latency).
Latency over IP Network 30ms + Network Latency (Main Station to Main Station).
Bandwidth used 300 kbps per active Talker, for a maximum of one talker
per device in the system.
Each Beltpack and Speaker Station counts as one
device.
Each Main Station and Remote Station counts as two
devices.
Each HLI-2W2 or HLI-4W2 counts as two devices.
IP version IPv4

4.2 Link Local Environments

4.2.1 What is link-local?
A link-local address is an IP address within the local segment of any network. Routers do not pass
information to these as link-local addresses are not guaranteed to be unique beyond a single
network segment. When first connected to a network, your HelixNet device will attempt to get an
IP address via Dynamic Host Configuration Protocol (DHCP). If no DHCP server is available, the
unit will automatically enter link-local IP mode. A link-local IP address will take the form:
169.254.xxx.xxx.
4.2.2 Working with a Device in Link-Local Mode
Devices will revert to link-local mode if they are configured to DHCP and fail to find a DHCP
address on the network or device they are attempting to connect to. Any DHCP enabled device
connected directly to a device in link-local mode using a standard Ethernet cable will enter link-
local mode automatically.
The HelixNet units will operate in link-local mode, but for optimum performance it is recommended
that they are used with either static or DHCP network settings. In link-local, the address will
change each time the device reboots resulting in potential loss of connection to endpoints.
Note: The easiest way to take a HelixNet device out of link-local mode is to allocate a new IP
address to the unit from the device front menus. Please ensure with your network
administrator that there will be no IP clashes with this address.
Page 66
Page 67
HelixNet | User Guide
4.2.3 Change the IP Address of a HelixNet Device from the Front Menu Screens
To change a unit’s IP address, you must first disable DHCP. Press the Menu button on front of
device to enter Menu mode.
1. To enable or disable DHCP
a. In Menu mode, select Networking.
Note: The Networking menu only appears if an Ethernet or Fiber interface module is
detected.
b. From the second menu, select Preferences.
c. From the third menu, select DHCP.
d. From the fourth display screen, select one of the following:
n Disabled
n Enabled (default)
2. To edit the IP address
a. In Menu mode, select Networking.
Note: The Networking menu only appears if an Ethernet or Fiber interface module is
detected.
b. From the second menu, select Preferences.
c. From the third menu, select IP Address.
d. From the fourth display screen, edit the IPv4 address.
Note: The HelixNet system uses 10.0.0.x and 172.23.x.x IP address ranges internally
between the Main Station and the Beltpacks, and therefore will not allow setting the
external IP address to anything in that range.
Note: If you change the IP address (either manually or through DHCP), the link between
stations will be broken and you have to reboot the Main Station to link again. The following
message will appear as a banner (inverted text) at the bottom across the four displays on
the Main Station
IP address | changed, | reboot | to link
If that message appears, pressing the Menu key will bring you directly to:
Administration->Reset->Reboot->Reboot Now

HelixNet | User Guide
4.2.4 Accessing the Core Configuration Manager (CCM) of a HelixNet unit in link­local mode
As an alternative to configuring your device from the front menu screens you can use the browser
based CCM.
To access the CCM of a HelixNet unit in link-local, you must connect to it from a computer that is
also in link-local mode.
A computer can be put into link-local mode by ensuring it is in DHCP mode and connecting it to a
unit that is already in link-local mode with a standard Ethernet cable. The computer will look for a
dynamically generated IP address (DHCP), and when it does not find one will enter link-local
mode automatically.
Once the computer is connected to the HelixNet device and in link-local mode, you can connect to
your unit by opening a browser window on the computer and inputting the unit’s IP address (from
the front panel display) into the address field. This takes you to the Core Configuration Manager
where you can configure the device as usual. See Core Configuration Manager (CCM) for more
detail.
Note: The units will operate in link-local, but for optimum performance it is recommended that
they are used with either static or DHCP network settings.
For the CCM password see CCM Password on page 152

5.6.4 Setting up a Key Expansion Group
Page 92
HelixNet units can be expanded and stacked to allow for visual monitoring and easy control of
multiple Channels. Up to five devices (HMS-4X, HRM-4X) can be stacked in an Expansion Group,
allowing for convenient observation and control of up to 24 Keysets. This gets rid of the need for
multiple key presses and microphones. When using this type of connectivity, the Expanded panels
act as slaves to the Host panel.
Page 93
HelixNet | User Guide
To set up an Expansion Group, once the devices have been connected to the same LAN by
Ethernet cable, you will need to identify a Host device. This is done from the front panel menu of
the device under Station Settings. Then designate the panel(s) to be stacked as Expansion
Panel(s).
Once this set up is established, you will be able to control all Channels from the Host panel.
Volume and buttons are synched.
Unused buttons on Expanded panel are disabled: HSet, Mic On, SA, All Talk, OPT, Main, PGM.
Restrictions:
Devices can only connect as an Expansion Group over LAN, not when connected over digital
Partyline.
HMS-4X or HRM-4X can act as Host Panel.
HMS-4X can only act as a key Expansion Panel to another HMS-4X.
HRM-4X can act as a Key Panel to an HMS-4X and an HRM-4X.
If an HRM-4X is already Paired to an HMS-4X, it will only see Host Panels that are part of the
same group.
If an HRM-4X is not Paired yet to an HMS-4X, it will see all Host Panels in the subnet and will
automatically Pair at the same time if a Host Panel is selected.
An Expansion Group must be set up from the device menus, and cannot be set up from the CCM.
