1.6 Clear-Com Cable Recommendations
Page 10
Use the following Category (Cat), American Wire Gauge (AWG) and shielded cable types:
Page 11
1.6.1 Cable recommendations
Category (Cat)
l Higher Cat numbers will support a higher bandwidth. Therefore, by
using a higher Cat number, you are future proofing your system to
some extent.
l Example: Cat5; up to 1G. Cat6; up to 10G.
l Use CAT5e or higher.
American Wire
Gauge (AWG)
l The lower the AWG number, the less temperature rise there will be
in the cable when using PoE. This is particularly important for
bundles. Local building regulations may rule out the use of 26AWG
or higher, depending on the installation. Check with your local
building regulations.
l Use AWG 24 or lower.
Shielded Twisted
Pair (STP) or
Foiled Twisted Pair
(FTP)
Using shielded cable means less problems with interference from other
sources. This means that your network will be more robust if you use
shielded cables.
Overall
Recommendation
Use CAT6a 23 AWG STP cable.

2 Powering your LQ
User Guide | LQ Series 4.2
Using the power supply unit (PSU)
l LQ units are supplied with a 24 watt sleeve-locking power connector.
l LQ-R 1RU units are supplied with two 60 watt sleeve-locking power connectors. Use either
power connector, or both to guard against one power supply failing.
Note: When connecting the sleeve-locking power cable, be sure to push until the connector locks into the
device.
Note: The 60 watt PSU can be used with the throw-down units if necessary.
Understanding power display icons
You will be able to see the power status of your device from:
l The front panel of the unit
l The device icon in the web based configuration tool (the CCM).
These indicators will show if the unit is using PoE or the PSU (LQ throw-down units), and which of
the two power supplies (or both) are in use for the LQ-R units.
Page 20
Page 21
LQ throw-down units
If the device is using the PSU, this will be lit up
instead of the PoE indicator.
LQ-R 1 RU units
User Guide | LQ Series 4.2
2.1 Using Power over Ethernet (PoE) with 2-Port Units
The 2-port units will receive power from the LAN1/PoE connector if required (this is not the case
for the larger LQ-R units).
When using PoE the LQ-2W2 supplies approximately 70 mA of power to drive the wired beltpacks
(about two beltpacks).
The units draw up to 12 watts of power (depending on what is connected to them), so when using
PoE you should have at least a Class 3 PoE switch.
If you exceed the power of your switch or network, the LQ device(s) will show a persistent flashing
green light, and not move beyond the Clear-Com splash screen. This indicates that the device is
continually booting and needs more power. Consider using the supplied sleeve-locking connector
cable or a higher Class PoE switch.
2.2 Power 2-Wire Beltpacks from the Partyline
2-wire beltpacks take power from the Partyline. The maximum numbers are shown in the table
below.
Page 21
Page 22
LQ series
unit
Power supply
Number of beltpacks powered by the
Partyline
LQ 24 watts 150 mA (~5 beltpacks) per device
LQ
PoE (device draws up to 12
watts)
70 mA (~2 beltpacks) per device
LQ-R 60 watts
250 mA (~10 beltpacks per pair of ports, max 20
per device)
2.3 Reboot System
The system will start its boot sequence immediately when power is applied. If you need to reboot
for any reason, either cycle the power or press all four direction keys on the control panel on the
front of the LQ unit at the same time.
User Guide | LQ Series 4.2

3.3 Overview
This page shows an overview of all the devices in your system. Devices in the upper part of the
page are the units in a Link-Group. As LQs are added to the group, they appear in this screen. A
HelixNet device can also be included in a Link-Group (LQ 4.0 and above).
On the lower part of the screen you can see the external systems that your LQ device is connected
to. These can be:
l IVC (matrix) connections
Page 24
l SIP (telephony interface) connections
l Agent-IC (mobile client) connections.
If you have a HelixNet in your Link-Group, you will see the remote units that are connected to the
HelixNet Main Station in the lower half of the Overview screen.

3.3.1 Device Configuration
Devices in a Link-Group can be configured either directly or by proxy, meaning that the
configuration operations for a unit are routed through the host device. The host device is the unit
which the browser is currently pointed to (orange highlight).
Click on the gear icon on any device.
You can use the Overview page to obtain diagnostic information for your all systems. Whenever
you see a > symbol, click to see a drop-down section.
Clicking the gear icon in any part of the CCM always takes you to programing options.

3.3.2 Resource Bar
User Guide | LQ Series 4.2
Page 27
About the Resource Bar
The Resource Bar is a tool that indicates the amount of processor power currently allocated on
that device.
l Bar orange = 70% of processing power reached
l Bar red = 80% of processing power reached
The device will work in the red zone, but the reliability of the audio response may decrease.
Page 28
The CCM will start limiting demands on the unit (for example it will prevent a port being added to a
Channel, or the addition of an IVC-32 or multi-Channel port) in order to maintain good audio
quality and responsiveness.
To optimize resource usage
l Reduce the network quality in the local audio mixes. Higher network quality takes more
resource.
l Reduce the number of ports that are in different Channels. Several ports in the same
Channel do not take much resource. It is more demanding if the ports are spread over
several Channels.
l Using a LAN/WAN/Routed Network Optimization mode will reduce the overall resource
usage (set Link-Group Optimization mode in the Linking page of the CCM).

3.4.5 Upgrade
Click Select File and navigate to where you have stored the upgrade file (.gz extension). Then
click Upgrade when the Upgrade button turns blue. Wait while the device reboots itself.
An LQ unit must be upgraded from the host device (the device that the browser is currently
addressing). The units cannot be upgraded by proxy.
To access a device directly as a host you must input that unit's IP address into a browser to access
the CCM. The host device always has an orange highlight.
Note: All devices in a Link-Group MUST be running the same version of the software; you must upgrade
all devices in the group.
After upgrades you are advised to check linking connections and auto null partyline ports.
3.4.6 Maintenance
Reset the unit to default settings.
Page 29
Reboot the system.
Create a support archive. Support Info provides a 'snapshot' of the device's operational
information for troubleshooting purposes.
Page 30
3.5 Network
Dynamic host control protocol (DHCP) or Static IP address allocation?
Default setting: DHCP
It is recommended that the Link-Master in a Link-Group has a static IP address.
Most networks use DHCP to allocate IP addresses. Because of this, DHCP is recommended for
fast set-up as the devices can be immediately connected to any network that provides DHCP. The
addresses provided are dynamic and may change from time to time. Because DHCP IP
addresses can change, the Link-Master should have a static IP address, or it may lose connectivity
to the group. Link-Local Environments on page 71
3.5.1 External IP address and External Port setting
For efficient networking, these details should be set for any LQ device that connects over a
firewall.
User Guide | LQ Series 4.2
Note: The Link-Master uses TCP port 80 for management, and TCP/UDP port 655 for audio. See
Linking over Internet or WAN below for port addressing and port forwarding details.
See your network administrator if you require network details.
3.6 Linking
In this page you can program a Link-Group. A Link-Group is a method for connecting LQ devices
over LAN, WAN or internet so they share audio and data between them.
A Link-Group can contain both LQ devices and HelixNet Main Stations (LQ 4.0 and above).
Page 30
Page 31
Devices can be seen and programmed from any device in the group.
User Guide | LQ Series 4.2
3.6.1 Link-Group Role
The Link-Master is responsible for synchronization and distribution of audio, Channel names and
device availability throughout the Link-Group. Each group needs a Link-Master.
To create a group you must connect LQ member(s) to a Link-Master. Change this setting to Link-
Member on the device to be connected to the master. When you change the role to Link-Member,
you can then enter the Link-Master IP address here to link the devices. Find the device IP in the
front menu screen of the device.
Note: If linking with a HelixNet Main Station, the HelixNet device must always be designated the Link-
Master.
Page 31
Page 32
User Guide | LQ Series 4.2
To take an LQ device out of a Link-Group, change it's role back to Link-Master here. This will
disconnect the device from the group.

3.6.2 Link-Group Optimization
Internet/NATed network (Default mode)
Use this setting whenever the network you are using crosses firewalls. This is the default mode
and will work with all networks. However, it requires more processing power of the LQ device and
may affect latency.
LAN/WAN network
Use this mode when using LQ in a private network. It uses less network and CPU resources and
gives better latency than the default.
3.6.3 Link-Master IP

3.7 Ports
Settings vary according to port type.
LQ 4.0 and above allows five different port types: 2-wire, 4-wire, GPIO, IVC and SIP. You will see
the port types available to your system in this page. Use the Port Selector to select ports for
programing. Use the drop-down device selector for moving between different devices in a Link-
Group.
In this page you can set port variables such as input gain (volume) and VOX detection. You can
name the port here. More than one port can be selected for configuration at one time.
You can also program the GPIO triggers for your system, allowing relays to be sent to radios or
other remote and third party equipment.
User Guide | LQ Series 4.2
In LQ 3.0 and above, it is possible to put ports in more than one Channel.
VOX settings are available on all LQ port types.

3.7.6 Multi-Channel Ports
It is possible to assign one port to many Channels. There is no limit on the amount of Channels a
port can be put into, but the rules for device resource usage apply. When the unit is reaching the
limits of its capacity, the user interface will stop you from assigning more ports.
When do I use multi-Channel ports?
An example of when to use multi-Channel ports might be if you have a program feed or stage
announce that should be heard by several teams or groups.
Enable multi-Channel port feature
Page 38
Page 39
User Guide | LQ Series 4.2
Once enabled, multi-Channel ports are available in the Assignments page, ready to be assigned to
more than one Channel.
Page 39
Page 40
User Guide | LQ Series 4.2
Note: If the port has already been put into a Channel, it will be unassigned from the Channel when you
enable multi-Channel support.
For more information on how to put ports in Channels see Assignments on page 41.
Note: Multi-Channel ports will not be placed in a local audio mix, they will be transported as a single
audio stream. You can use the Resource Meter as a guideline for device capacity.
3.8 Roles
When using LQ, some of the products you interconnect with use Roles for the purpose of intercom
setup. Roles are preset configurations, used to simplify and control your intercom installation. You
can work with default Roles which can be cloned or edited. You can also create your own Roles if
required.
The products that use Roles when connecting to LQ devices are: HelixNet and Agent-IC.
When a HelixNet device is linked to LQ in a Link-Group set up, the Role configuration from the
Master HelixNet device will override the LQ units.
For more information about HelixNet Role configuration, see the HelixNet User Guide, available
from the Clear-Com website.

3.9 Assignments
Network transmission controls/transport settings are in this page (LQ only).
This is where you will assign ports to Channels. All devices, with their associated ports appear in
the left margin of this page.
In the center are three tabs; chose from All, Channels and Directs.
Channels (up to 24 in total per Link-Group) are shown on the right.
To route audio:
1. Choose Channel type; Channel or Direct.
2. Click on an available Channel to select it or click '+' to create a new one.
3. With the Channel selected (orange highlight), click '+' next to the port you require to put into
the Channel.
4. Repeat step 3 as often as required.
User Guide | LQ Series 4.2
Page 41
Page 42
Note: Network transmission controls (submix) are in this page.
3.9.1 Channel or 4W Direct Channel?
An LQ Channel is made up of multiple audio sources which operate as a partyline. All sources in a
Channel can hear and talk to each other. A 4-wire direct (panel) Channel, by contrast, is a
connection between two ports only. A 4-wire direct (panel) connection cannot be included in a
Channel and is configured separately.
Note: Direct Channels are not available in a HelixNet system.
3.9.2 Local Audio Mix (LAM)
Each LQ device within a Channel performs its own local audio mix (submix). The LAM mixes audio
at a very early stage of the audio transport which reduces the latency of the audio streams (below
4ms) and improves audio processing. LAM is a way of improving latency, increasing the capacity
of an LQ device in certain user cases and reducing network usage.
The LAM is performed automatically when ports are added to a Channel.
User Guide | LQ Series 4.2
Note: The ports from each LQ appear within a box, with the local audio mix icon in the bottom right
corner, where you can program network settings.
Network settings within a Channel are set on a per-device basis. To set differing network quality
for ports from the same device, put the ports in separate Channels.
Note: LAM is not available if you are using a HelixNet/LQ Link-Group.

This is done to conserve network resources.
3.9.4 Recommended network settings
l Internet - very low or low
l LAN/WAN - balanced or high
l LAN only - very high. This option enables 20 kHz bandwidth.
3.9.5 Custom setting
User Guide | LQ Series 4.2
The Custom option allows adjustment of the jitter buffer setting independent of bit rate and packet
size.
The jitter buffer setting is designed to buffer audio received to prevent loss if there is network jitter.
Note that the jitter buffer selection will directly affect the latency. This is because the lower number
in the jitter range represents the amount the LQ unit will buffer audio before delivering it to the port.
A bigger jitter buffer setting will increase latency in milliseconds.
Note: The network setting is the bandwidth from the LQ device into the IP network.
Note: Within the Custom setting, selecting an Audio Bitrate of 128 Kbps will automatically set Bandwidth
to 20 kHz,

For more information see:
Static IP configuration on page 69
4.2 Creating a Link-Group
Before linking units together, one LQ device must first be designated as the Link-Master by setting
that device's role to Link-Master. Every other LQ device within the Link-Group will then be set into
a Link-Member role which allows the linking of those unitsdirectly to the Link-Master.
When creating a HelixNet/LQLink-Group the HelixNet must always be designated the Link-
Master.
Page 48
Page 49
In this example, LQ #1 will be left as Link-Master (default configuration) and LQ #2 will be linked to
it.
4.2.1 How to create a Link-Group
1. Navigate to Device > Linking on the CCM of LQ #2.
2. Click Change Role to Link-Member.
User Guide | LQ Series 4.2
3. Within the Link-Master IP address field, enter the IP address as displayed on the LQ #1
device. Click on blue check mark or press <ENTER> key to submit.

5. Click Apply changes.
LQ #1 and LQ #2 will now be linked (operation may take up to 30 seconds to complete). If
there is existing configuration on the member LQ, this will be replaced by the configuration of
the master.
6. Navigate to the Overview page (top navigation bar). Both LQ devices should be displayed on
this page.
7. Before continuing, if either LQ device is a LQ-2W2 model, you may need to auto-null both
ports (power must be present on the 2W circuit before auto-null is possible). For each device
to be auto-nulled, navigate to Device > Ports.

4.4 Clear-Com Cable Recommendations
Use the following Category (Cat), American Wire Gauge (AWG) and shielded cable types:
Page 52
Page 53
4.4.1 Cable recommendations
Category (Cat)
l Higher Cat numbers will support a higher bandwidth. Therefore, by
using a higher Cat number, you are future proofing your system to
some extent.
l Example: Cat 5; up to 1G. Cat 6; up to 10G.
l Use Cat 5e or higher.
American Wire
Gauge (AWG)
l The lower the AWG number, the less temperature rise there will be
in the cable when using PoE. This is particularly important for
bundles. Local building regulations may rule out the use of 26AWG
or higher, depending on the installation. Check with your local
building regulations.
l Use AWG 24 or lower.
Shielded Twisted
Pair (STP) or
Foiled Twisted Pair
(FTP)
Using shielded cable means less problems with interference from other
sources. This means that your network will be more robust if you use
shielded cables.
Overall
Recommendation
Use Cat 6a 23 AWG STP cable.

6 Linking
6.1 What is a Link-Group?
A Link-Group is a set of LQ devices connected over IP so they share audio and data between
them.
With LQ 4.0 and above a HelixNet device can also be included in a Link-Group. This increases the
available ports and the range of a HelixNet system.
User Guide | LQ Series 4.2
Page 59
Page 60
User Guide | LQ Series 4.2
The Core Configuration Manager (CCM) for any LQ host can be accessed by entering the IP
address as displayed on the front panel display of the LQ host into a web browser's address field.
All devices in the Link-Group can be viewed and configured through any single host in the Link-
Group.
Note: A HelixNet Main Station can also be linked in a Link-Group formation. The basic principles are the
same for a HelixNet/LQ Link-Group, though there are a few differences in operation.
For more information, see:
LQ to HelixNet Connectivity on page 132
6.2 About Linking
A Link-Group:
l Can contain up to 6 LQ devices or up to 6 of a combination of HelixNet Main Stations and
LQ devices
l Must have one unit designated as Link-Master
l Performs a “best effort” approach to creating a mesh network between all the devices within
the group.
Page 60
Page 61
User Guide | LQ Series 4.2
6.3 The Link-Master role
The Link-Master role serves three main purposes:
1. It facilitates Link-Group membership.
2. It is the owner of Channel names, meaning that Channel names will only persist (be
maintained consistently) if the Link-Master is operational.
3. It is responsible for the synchronization and distribution of both configuration and device
availability status throughout the Link-Group.
Note: The Link-Master must be reachable on TCP port 80 and TCP/UDP port 655 by all devices
within the Link-Group. (Use TCP port 443 if you are using secure HTTPs.)
Note: It is recommended that the IP address of the Link-Master is allocated statically. When allocated
by DHCP the IP address can change. If this happens the LQ devices will no longer be able to
reach the Link-Master device.
Note: Any device can be set to Link-Master mode. Link-Master mode is the factory default setting.
Page 61
Page 62
6.4 The Link-Member role
LQ devices that are not designated master will have the role of Link-Member. Joining a device to
a Link-Group requires that device to be set to Link-Member role which will prompt the user to
enter the address of the Link-Master.
If a Link-Member device loses connection to its Link-Master, the front panel LED of that device
will turn red until the connection is restored.
6.4.1 Linking units
The only way to join devices to a Link-Group is through the Linking page of the CCM. Only the IP
address of the Link-Master is required during this set up.
6.4.2 LQ restricted IP range
LQ units use the IP range 172.23.xx.xx for linking. Because of this, this IP range should not be
used for any devices (including LQs) when working with the LQ Series system. Clear-Com cannot
guarantee reliable behavior if this address range is used.
User Guide | LQ Series 4.2
6.4.3 Linking over a LAN
This is the simplest way to link devices together. This type of environment enables the highest
potential level of communication quality and the best availability of resources. When linking over a
LAN, set Link-Group Optimization to LAN/WAN routed network in the Linking page of the Core
Configuration Manager (CCM) for best latency performance and use of resources.
Note: External linking is disabled when Link-Group Optimization is set to LAN/WAN Routed
Network.
6.4.4 Linking over Internet or WAN
When linking over the public Internet, addressing of the Link-Master becomes more complicated
as the Link-Master must be made externally reachable to all Link-Members. This is achieved by
creating port forwarding rules within the firewall.
Note: A HelixNet/LQ Link-Group does not operate over the Internet. This is because the codec that
HelixNet uses (WavPack) is not optimised for the Internet. Internet connectivity when using
HelixNet and LQ is achieved using a tie line.
Page 62
Page 63
6.5 How to link LQ units over a firewall
User Guide | LQ Series 4.2
The Link-Master uses TCP port 80 for management and TCP/UDP port 655 for audio (port 443
for management if you are using HTTPs). You will need to create port-forwarding rules within
your firewall to make these ports externally accessible to the Link-Master device.
When creating a Link-Group over the public internet, Link-Members need to be given the Link-
Master’s externally reachable IP address and the port that is forwarded to port 80. This
information is entered in the Linking page of the CCM.
Note: If no port forwarding rules have been applied the LQ devices will find the correct default ports
automatically, so there is no need to specify a port.
Once the devices are linked in a group, they will share network details with each other
automatically. To facilitate this, the network details, including the port that is forwarded to
TCP/UDP port 655 need to be configured in the Link-Master’s Network page. If no port
forwarding rules have been applied, it is not necessary to specify a port.

6.6 How to Remove a Device from a Link-Group
6.6.1 Remove an on-line Link-Member from a group
1. Access the browser-based CCM for any device within the Link-Group.
2. In the Overview page, click on the device image of the unit that you want to remove from the
group.
3. Navigate to Linking for that device.
4. Click Change Role to Link-Master.
5. Apply Changes.
The device will be reconfigured as a Link-Master and removed from the group.
User Guide | LQ Series 4.2
6.6.2 Remove an off-line Link-Member from a group
1. Access the Core Configuration Manager for any device within the Link-Group.
2. In the Overview page, the off-line unit will show a red ‘X’. Click on this device.
3. You will be asked if you want to remove this unreachable device. Click Delete.
The device will be removed from the Link-Group.
If this same device is powered on again, it will automatically seek the same Link-Master and ID
slot. If the ID has been taken by another device, it will take the next available ID. If no ID is
available (because there are already 6 devices in the group) it will not be able to join the group.
To re-use this device with a new Link-Master, it must be returned to the default role (Link-Master)
and then re-linked.

7 Interface Port Configuration
7.1 Call signaling and Remote Mic Kill (RMK)
Call signaling is automatic on all audio routes so a call signal can be routed to any destination (2-
wire or 4-wire).
Call signaling will be passed to some third party intercom equipment, but it may not be
recognized.
RMK is supported and passed through to 2-wire participants only.
7.2 2-wire specific port options
Default option is shown in bold.
User Guide | LQ Series 4.2
7.2.1 Device interface settings
Power: Disabled/Enabled. Enable power if you want to power partyline beltpacks from the line.
See Power 2-Wire Beltpacks from the Partyline on page 21 for more information.
Note: Enabling power will enable termination by default.
Mode: Clear-Com/RTS. For pinouts for each of these see Pinouts on page 193.
7.2.2 2-wire specific port settings
l Input/Output gain: -3 to +3 dB. Default = 0.
l Termination: Disabled/Enabled. Termination is used to eliminate echo and distortion
when 2 or more 2-wire devices are connected. This setting is automatically enabled when
power is enabled on the line. It can be toggled on and off as power should only be
terminated once within any series of connected devices.
l Autonull. Autonull should be started whenever 2-wire devices are connected or re-wired.
Do not listen in on the headset while autonull is being performed.
7.3 4-wire specific port options
Note: To minimize noise, use screened (shielded) cable when connecting 4-wire ports.
l Input/Output gain: -12 to +12 dB. Default = 0.
l Port function (sets pin polarity of cable) : to Matrix/to Panel. .
Page 66
Page 67
User Guide | LQ Series 4.2
l Baud rate: 9600 (Drake 4000)/19200 (Eclipse). Select baud rate according to which type
of equipment you are connecting.
7.4 4-wire + GPIO specific settings
l Output level: Mic Level (-55db)/Line Level (0 dB).
This setting is used when connecting to devices (like a hand-held radio) where audio connects
directly to the mic. This setting works in conjunction with the Output Gain; overall gain = Output
Level + Output Gain.
7.5 GPIO action triggers (4-wire + GPIO and IVC-32 ports)
Default option is shown in bold.
GPI action trigger: Disabled/Network Control Event 1/Network Control Event 2/Channel Call
Event.
Assign a Network Control Event on detection of a GPI signal).
GPO action trigger: Disabled/Network Control Event 1/Network Control Event 2/Channel Call
Event (assign which Network Control Event will trigger the GPO).
GPO Off Delay: None to 2 seconds. This sets a delay on the deactivation of the GPO after a
Network Control Event has disappeared.
Test: use to check that the GPO is firing (hardware).
For detailed explanation and examples of how to use Network Control Events see What are
Networked Control Events and How Do I Use Them? on page 92
7.6 IVC-32 specific port settings
Network Quality: EHX Managed/Very High (LAN)/High (WAN)/Low (internet). The default
setting is EHX Managed.
Silence Supression: Enabled/Disabled. When enabled, Silence Supression will detect silence
on the line, and will stop transmission and implement comfort noise when this occurs. This
conserves network resources.

7.7 Port settings
l Label: Clicking/touching the blue label header will allow you to change the name of the
port. Enter the new name and click the blue check mark to apply changes.
l Multi-Channel support: Enabled/Disabled. Enable this option to use the audio source in
more than one Channel or direct connection.
7.8 VOX (audio-gating)
The VOX setting has several functions:
l VOX can be used to maximise bandwidth efficiency by detecting when the line is silent
and not transmitting at those times.
l VOX can be used to trigger a Network Control Event (used for sending and receiving
GPIO signals) when audio is detected in the Channel.
User Guide | LQ Series 4.2
l VOX can be used to eliminate unwanted noise, for instance, low level ambient or
background noise.
l VOX mode: Disabled/Fixed Threshold/Adaptive.
If Disabled, VOX is not activated and Network Control Events cannot be configured. Audio is still
detected in the Channel, so audio light will show.
Fixed Threshold: triggers VOX detection (audio gating) according to a fixed level . Enabling this
option automatically enables Threshold and VOX Delay.
Adaptive: sets the audio trigger according to an automatically calculated 'noise floor'. This option
implements comfort noise when silence is detected. Only the Off Delay option is activated with
this setting. The Adaptive threshold is not suitable for transmitting music.
l VOX Off Delay: 0.5 to 4 seconds. Delays the deactivation of the noise gate to allow the
signal to stabilize.
l VOX Threshold: 0 to -42 dB (default = -22 dB). Set the level at which audio is considered
valid in the Channel.

8 Network Settings (IP)
8.1 Dynamic Host Configuration Protocol (DHCP)
The default method for LQ devices to obtain an IP address is DHCP.
Most networks allocate IP addresses using DHCP.
8.2 DHCP or Static IP addressing?
DHCP can be used for quick set-up and the units will work with DHCP IP addressing. However,
the address provided by DHCP are dynamic and can change, so in some cases it is better to
allocate static IP addresses to ensure a completely stable system.
A static IP address is generally recommended for the Link-Master, while the Link Members should
use DHCP.
If there are additional Port Forwarding rules created in the firewalls that enable external
connectivity to the Link-Members as well as the Link-Master the Link-Member units should also be
given static IP addresses.
User Guide | LQ Series 4.2
See Linking over Internet or WAN on page 62
8.3 Static IP configuration
DHCP is not recommended for the Link-Master and is not recommended for units linked to the
master in some situations.
In these cases you will allocate the network settings statically. To do this, navigate to: Device >
Network in the Core Configuration Manager (CCM).
Page 69
Page 70
User Guide | LQ Series 4.2
8.3.1 Netmask or Subnet
The netmask or subnet divides the network into sectors for more efficient routing and is required
when allocating a static IP address to an LQ device.
8.3.2 Gateway
This setting is required when traversing across internets.

8.4 Link-Local Environments
8.4.1 What is link-local?
User Guide | LQ Series 4.2
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 LQ 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.
8.5 Accessing an LQ Unit when in Link-Local Mode
To access the CCM of an LQ unit in link-local, you must connect to it from a PC that is also 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. A PC can be put into link-local
mode by ensuring it is in DHCP mode and connecting it to the LQ unit that is in link-local with a
standard Ethernet cable. The PC will look for a dynamically generated IP address (DHCP), and
when it does not find one will enter link-local mode automatically.
Once the PC is connected to the LQ and in link-local mode, you can connect to your LQ 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.
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.

User Guide | LQ Series 4.2
9 Internet Connectivity
All devices within a Link-Group must have connectivity to the Link-Master on TCP port 80 (TCP
port 443 if using the HTTPs protocol) and TCP/UDP port 655. When linking devices over the
Internet, make sure that this connectivity is stable. Internet connection to an LQ device requires
special configuration within your firewall (port-forwarding).
Note: LQ devices cannot connect using the Internet if they have a HelixNet Main Station as link master.
9.1 Getting an external IP address
When networking LQ devices over the Internet, an external IP address from which the Link-Master
is reachable is required as a first step in making sure Link-Members can get to the Link-Master.
The external (public) IP address must be static and non-changing. Normally an Internet Service
Provider (ISP) will provide external addressing in Dynamic Host Configuration Protocol (DHCP)
mode.This is not guaranteed to remain static but instead may change periodically.This will cause
linking issues as the Link-Members will not be able to reach the master if the IP address changes.
Therefore, it is suggested that you purchase a static address from your ISP. Failure to do this
could result in a loss of service.
9.2 Port-forwarding
To connect to an LQ unit that is behind a firewall, certain ports must be mapped from your firewall
to the LQ device.This mapping will forward traffic received on those ports from the Internet
directly to the LQ unit.
l The Link-Group uses TCP port 80 (port 443 for HTTPs) for linking, data distribution and
browser-based management.
Page 72
l The Link-Group uses port 655 (TCP and UDP) for group connectivity and audio
transmission.

10 Secure HyperText Transfer Protocol (HTTPs)
10.1 What is HTTPs?
HTTPs is an adaptation of the HTTP protocol. It is commonly used for security when sending
sensitive data over a network.
HTTPs protects against an intermediary being able to intercept data between devices. HTTPs
uses data encryption and Public Key Cryptography to create a secured channel.
Using HTTPs with LQ Series 4.0 and above units involves:
l Installing a security certificate on the browser used to reach the Core Configuration
Manager (CCM) of the LQ devices
l Redirecting IP traffic to the HTTPs port (443) using the Force HTTPs feature. This feature
is found in the CCM of each device. The default setting for this feature is Disabled.
10.2 Why Use HTTPs with LQ Series Units?
When using the LQ Core Configuration Manager (CCM) to establish your intercom setup, you
might wish to protect your login credentials and configuration details from unauthorized
interference. In this case you will establish an encrypted connection between the CCM and the LQ
devices using HTTPs.
The LQ units use port 80 (http) and port 443 (https) for management. Once a Link-Group is
established, audio travels in an encrypted channel between units via port 655. However, the
management ports will continue to exchange configuration information once the audio channel is
established, and you might want to ensure that this information travels on a secured route.
For more information about a Link-Group and Linking see:About Linking on page 60
For more information about establishing a Link-Group using HTTPs see: Setting up a Link-
Group Using HTTPs on page 79
10.3 How to Use HTTPs with LQ Series Units, Overview
It is helpful to know how to set up an LQ device (Basic set up) and a Link-Group (Create a Link-
Group) before establishing a secure connection. Please refer to the relevant sections in this
manual if necessary.
Page 73
There are two main steps to establishing an encrypted connection on the management ports of the
LQ units.
Page 74
User Guide | LQ Series 4.2
1. Choose and install a suitable security certificate on the browser used to access the Core
Configuration Manager (CCM) of the LQ units.
2. Enable the Force HTTPs feature on the LQ Series 4.0 and above unit. When you enable the
Force HTTPs feature on an LQ unit, HTTP is turned off for that LQ unit and traffic is redirected
to the HTTPs port. The Force HTTPs feature is found in the Network page of the CCM under
the Security tab. The default setting for this feature is OFF.
You must choose and install a security certificate and test it before enabling the Force HTTPs
feature in the Core Configuration Manager (CCM).
Test the certificate by typing https:// LQ IP address in the browser URLfield :
Page 74
If the browser does not recognise the certificate as valid it will issue a warning:
Page 75
Example browser exception:
User Guide | LQ Series 4.2
Page 75
When correctly installed, your browser will use the certificate to authenticate its HTTPsconnection
with LQ devices, giving an encrypted connection between the browser and the LQ unit and also
between devices in a Link-Group.
Page 76
User Guide | LQ Series 4.2
Note: The security certificate must be installed on every instance of a browser that is used to access the
LQ unit. If you are working with a Link-Group, each browser used to access the devices must have
a certificate installed.
Relevant Information:
l LQ devices are designed to work with both HTTP and HTTPs. Enable the Force HTTPs
feature to turn off the HTTP port and redirect traffic to the HTTPs port. This contributes to a
secured connection between the devices.
l HTTP us routed through port 80
l HTTPs is routed through port 443
l There are 3 types of security certificate available for use with your LQ device:
l A certificate of your own choosing (fullchain and private key)
l An EasyDNS authorized certificate for *.clearcomdevices.com
l The Clear-Com self-signed certificate.
l Depending on which certificate you use, you may have to register your LQ devices with a
DNS server.
l If you try to Link to or access the CCM of a device that has been set to Force HTTPs using
the HTTP protocol, you will get a device not found type message as the HTTP port has
been turned off. If a device has been set to Force HTTPs in the CCM, you must use HTTPs
to reach the device.
10.4 HTTPs Certification Browser Support
Each browser type (for example; Safari, Chrome, Edge, Firefox) uses its own method for HTTPs
certificate management, and these methods can change with time. As this information is beyond
the control of Clear-Com, please refer to the instructions supplied with your browser if you require
more information about how the browser you are using works with certification support.
10.5 Certification Authority (CA) Options for Use with LQ Units
Page 76
3 security authorization options are available. Choose the certification option that is best suited to
your security requirements.
1. A certificate of your own choosing.This option gives you complete control over the
security of your Link-Group. Choose this certificate if protecting the details of your intercom
configuration is critical. This option requires some specialized knowledge. You will need to
know how to obtain a fullchain certificate and a private key, and how to install them on your
browser. When using your own certificate you might have to provide a DNS server address
Page 77
User Guide | LQ Series 4.2
and register the LQ device.
2. The EasyDNS security certificate.
This is a commercially certified certificate.
When using the EasyDNS certificate, you have to provide a DNS server address for LQ
registration.
If you use this certificate, the browser needs Internet access to verify the certificate
authenticity. This is because the browser will verify with AlphaSSL and GlobalSign that the
certificate is valid.
3. The Clear-Com self-signed (default) certificate. This certificate can be downloaded and
installed for use with an HTTPs connection. It is used to encrypt the audio channel that the LQ
devices establish on port 655 (linking). It also verifies all Agent-IC connections to LQ. This
certificate can be used in a private network. It does not require Internet access to confirm its
authority.
Warning:
Browsers are not set up to recognize self-certification. Using the Clear-Com self -signed certificate
(option 3) is likely to cause your browser to issue a warning.
This example shows a warning posted by the Chrome browser:
Page 77
Page 78
User Guide | LQ Series 4.2
Page 78
Page 79
User Guide | LQ Series 4.2
To work with the Clear-Com self-signed certificate, you will need either to find a way of disabling
the warning (for example, install the certificate in the trusted certificates root directory), or make a
choice to ignore the warning and proceed to the insecure connection. This is not a conventional
way of working with your browser’s security features, but will provide a certain level of security if
your Link-Group does not have Internet access.
Note: An iOS browser will only work with its own chosen certificates, so the Clear-Com self-signed
certificate cannot be used in this context.
10.6 Setting up a Link-Group Using HTTPs
Page 79
LQ units establish a robust mesh network when transporting audio (see image above). The units
use a series of IP ports to create this mesh:
Management (login credentials, setup details, IP addresses)
l TCP port 80 (HTTP)
l TCP port 443 (HTTPs)
Linking (audio)
l TCP/UDP port 655 (encrypted channel)
Page 80
User Guide | LQ Series 4.2
The devices will pass management details via either port 80 or port 443 (depending on which
prototcol is used). To ensure this information passes via an encrypted route, enable the Force
HTTPs feature on every LQ device in the Link-Group. The devices will pass information on either
management port, but the route will not be secure unless all the devices use HTTPs.
To create a Link-Group using the HTTPs protocol you will follow the same procedure as when
using HTTP; you must give the member unit the IP address of the Link-Master unit. When linking
units over the HTTPs protocol, you must specify HTTPs in the Linking page of the Link-Member.
For more information on the Linking procedure see: Creating a Link-Group on page 48
The port number does NOT need to be specified unless you are linking units over a firewall where
port forwarding rules apply. In this case (units traversing a firewall to reach each other) you must
specify the external IP address and the external port, so the units can cross the firewall.
Note: If you try to link to a device that has been set to Force HTTPs without specifying HTTPs , you will
get a device not found message because the HTTP port is turned off.
Note: Before using the Force HTTPs feature, you must first install a security certificate on your browser.
When using HTTPs with a Link-Group, every browser instance used to reach and configure the
devices must have a security certificate installed.

10.7 Registering an LQ Unit with a DNS Server
When registering with a DNS server, the LQ unit will try and register two entries in the DNS it is
connected to:
l lq-[MACAddress].clearcomdevices.com with its LAN IP address
l lq-[MACAddress]x.clearcomdevices.com with its external IP address.
This means that the LQ can usually be reached by typing the DNS hostname into a browser.
10.8 How to Set Up an HTTPs Connection between a Browser and an LQ Unit
10.8.1 Install a security certificate on your browser
1. Choose a security certificate. See Certification Authority (CA) Options for Use with LQ
Units on page 76 for more information.
2. Open the CCM of your LQ unit.
Page 81
3. Navigate to Device>Network>Security.
Page 82
User Guide | LQ Series 4.2
4. Install the certificate. The three certificate options are covered below, choose a., b., or c.
a. A certificate of your own choosing:
Page 82
Page 83
b. The EasyDNS certificate:
User Guide | LQ Series 4.2
Page 83
Page 84
c. The Clear-Com self-signed (default) certificate:
User Guide | LQ Series 4.2
Page 84
5. Test the certificate by typing the HTTPs IP address into your browser URL field in the format:
HTTPs:// XX.XX.XX.XX :
Page 85
User Guide | LQ Series 4.2
If you see the green 'secure' symbol and the browser does not issue an exception, the
certificate is working.
Note: When using your own certificate or the EasyDNS certificate, the LQ unit must first be registered
with a DNS server. If required, your network administration department should provide advice on
this. When using the Clear-Com default certificate, the device does not need to be registered with
a DNS server. The Clear-Com default certificate can be used with a set up that does not have
Internet access.
Note: Different browsers (for instance, Chrome, Firefox) have different methods for handling
certification. This is beyond the control of Clear-Com. You may need to refer to the instructions
that come with your browser for this.

11 Clear-Com Eclipse Matrix Connections
Each LQ unit (LQ 3.0 and above) can support up to 8 IVC-32 ports, as well as its own hardware
ports.
l Up to 8 IVC-32 ports per LQ device
l Up to 32 IVC-32 ports per Link-Group
l IVC-32 ports are generated in the External Systems page in the CCM
l All ports, LQ hardware ports and IVC-32 ports can then be used in the LQ Channels to
transmit audio, Call and GPIO signals.
User Guide | LQ Series 4.2
Each LQ-R unit supports up to 24 ports: 8 hardware ports, 8 SIP ports and 8 virtual ports. Agent-
IC and IVC ports are considered 'virtual ' ports. Virtual ports can be used in any combination up to
8 in total.
11.1 How to create virtual ports and connect to a matrix
11.1.1 General outline
Both matrix and LQ must be connected to a network and able to reach each other across the
network settings.
To set up this connection:
Page 87

When the LQ is connected to the IVC-32 card, a green status LED shows. If the connection is not
successful, a yellow warning displays. Click the yellow warning symbol for information.
11.5 Put new ports into a Channel
Once ports are created, they can be seen in the Assignments page and put into Channels.
Page 90
Page 91
User Guide | LQ Series 4.2
Once a virtual port is associated to an LQ device you can adjust the port setting. Click the cog icon
to go straight to Ports page.
If you want to pass GPIO controls over the network using LQ you must program Network Control
Events. See What are Networked Control Events and How Do I Use Them? on page 92
Page 91
Page 92
User Guide | LQ Series 4.2
12 What are Networked Control Events and How Do I Use
Them?
12.1 About Networked Control Events
Networked Control Events are used to program input and output triggers (GPI/O) in your intercom
system. They are designed to allow maximum flexibility and scalability in your use of GPIO events.
For example, Networked Control Events can be used to enable radio communication over IP, or
send a control signal from a panel, via a matrix to a radio. The GPO can also be used to turn on an
'on-air' light, or perform any other function you require.
A Networked Control Event occurs when the input trigger and the output trigger on ports in a
Channel are set to the same value.
Active Networked Control Events can be viewed in the Assignments page in the CCM.
Networked Control Events
12.2 How to set up Networked Control Events
1. Configure the input trigger on a port. This example shows audio entering a 4-wire port (VOX)
on an LQ 4W2 device that triggers the output relay on an LQ GPIO device.
Page 92
Page 93
User Guide | LQ Series 4.2
2. Configure the output (GPO) on a port.
Page 93
3. Put both ports together in a Channel . This activates a Networked Control Event when an
input and an output Networked Control Event setting match. A GPO is then fired.

This example shows how to send a GPO (General Purpose Output) trigger to a third party radio
when audio comes in from an Encore RS701 beltpack. This can be used to open audio
transmission on the radio; equivalent to pressing the Push To Talk (PTT) button on the radio.
The GPO is triggered by LQ models that have a GPO port; LQ-4WG2, GQ-R2WG8 and LQ-
R2W4+4WG4.
Note: For this configuration Link Group must already be established. See Creating a Link-Group on
page 48 for more information.
12.6.2 General set up outline
1. In port settings, on the device and port connected to the belpack, set the VOX (audio
detection) to trigger Network Control Event 1
2. On the device and port connected to the radio, set the GPO to trigger on Network Control
Event 1
3. Bring both ports together into a Channel
4. When audio comes in from the beltpack, the GPO will fire. You can test this relay using the
TESTbutton.
