2 Powering your LQ
User Guide| LQ Series 4.0
2.1 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.

User Guide| LQ Series 4.0
2.1.1
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.
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
2.2 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.
2.3 Power 2-wire beltpacks from the Partyline
2-wire beltpacks take power from the Partyline. The maximum numbers are shown
in the table below.
2.4 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.
The system can also be rebooted using the front panel menu screens: Menu >
Administration > Reboot and from the CCM: Device > General >
Maintenance > Reboot.

3.1.1 Minimum requirements for the CCM
Supported on the latest versions of all major web browsers (i.e. Google Chrome,
Safari, Firefox, Internet Explorer, Opera).
Page 22
Page 23
3.2 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
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.

3.2.1 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.

3.2.2 Resource Bar
User Guide| LQ Series 4.0
3.2.3
3.2.4
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.
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.
Page 25
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).

After upgrades you are advised to check linking connections and auto null partyline
ports.
3.3.6
Maintenance
Reset the unit to default settings.
Reboot the system.
Create a support archive. Support Info provides a 'snapshot' of the device's
operational information for troubleshooting purposes.
3.4 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.
Page 27
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
Page 28
User Guide| LQ Series 4.0
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.
For more information, see:
Network settings (IP) on page 67
Internet connectivity on page 71
Link-local environments on page 69
External IP address and External Port setting
For efficient networking, these details should be set for any LQ device that connects
over a firewall.
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.
For more information, see:
Linking over Internet or WAN on page 60
Internet connectivity on page 71
See your network administrator if you require network details.
3.5 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.

3.6.6 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.

User Guide| LQ Series 4.0
3.6.7
Enable multi-Channel port feature
Once enabled, multi-Channel ports are available in the Assignments page, ready to
be assigned to more than one Channel.
Note: If the port has already been put into a Channel, it will be unassigned from the
Channel when you enable multi-Channel support.
Page 38
Page 39
User Guide| LQ Series 4.0
For more information on how to put ports in Channels see Assignments on page
40.
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.
For more information, see:
Resource Bar on page 25
3.7 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.
For more information about Agent-IC Role configuration see Agent-IC and LQ on
page 137

3.8 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.
Page 40
Page 41
User Guide| LQ Series 4.0
Note: Network transmission controls (submix) are in this page.
3.8.1 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.
3.8.2 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.
Page 41
Page 42
User Guide| LQ Series 4.0
The LAM is performed automatically when ports are added to a Channel.
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.
3.8.3 Local Audio Mix/transport settings
Click/touch a blue label in the CCM to access settings.
Silence suppression. Default = Disabled
Enabling this option will stop transmission and implement comfort noise when
silence is detected. This is done to conserve network resources.

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,

4.1 Setting up your LQ environment within a LAN
Gather the following equipment:
l 2 x LQ units (LQ #1 and LQ #2)
l 2 x provided Power Supply Units (PSUs)
l 2 x Straight-through RJ45 Ethernet cables
l 1 x Network connection with Dynamic Host Control Protocol (DHCP) server
present (preferred method)
l 2 x 2-wire, 4-wire and/or GPIO equipment to provide an audio connection to
each LQ
l 2 x 2 Network connections available for connecting each LQ to your network.
1. Connect either LAN port of LQ #1 to the local network equipment.
2. Connect either LAN port of LQ #2 to the local network equipment.
3. Connect the provided PSU to each LQ device. Once booted, each device will
display an IP address on the front panel display.
Page 45
Page 46
User Guide| LQ Series 4.0
4. Once the devices are operational, you will program each device through the
browser-based Core Configuration Manager (CCM).
5. Access the CCM. From a device connected to your network, open a Web
browser. Enter the IP address as displayed on LQ #2 device in the address field
of the Web browser (Chrome, Safari, Firefox, IE, Opera). This takes you to the
CCM.

Page 46
Page 47
User Guide| LQ Series 4.0
Note: The IP address will be allocated by DHCP (default mode). In the event that the
network does not serve DHCP or there is no network connection, the IP address will
revert to a link-local address. If necessary IP addresses for the devices can be
configured in the Network page of the CCM. See information links at the bottom of
this page if you require more information.
7. Connect the audio equipment to Port A of each LQ device.
8. Once the LQ devices are set up, proceed to Creating a Link-Group on page

User Guide| LQ Series 4.0
For more information see:
Static IP configuration on page 67
4.2 Creating a Link-Group
Before linking units together, one LQ device must first be designated as the LinkMaster 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/LQ Link-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 4.0
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.
4. The next available Device ID will be selected by default (highlighted in blue) but
can also be manually selected.
Page 49
Page 50
User Guide| LQ Series 4.0
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.

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 4.0
Page 57
Page 58
User Guide| LQ Series 4.0
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 130
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
Page 58
l Performs a “best effort” approach to creating a mesh network between all the
devices within the group.
Page 59
User Guide| LQ Series 4.0
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 433 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 59
Page 60
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 4.0
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 LinkMembers. 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 60
Page 61
6.5 How to link LQ units over a firewall
User Guide| LQ Series 4.0
The Link-Master uses TCP port 80 for management and TCP/UDP port 655 for audio
(it uses port 433 for management if you are using HTTPS rather than HTTP). 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
6.6.2
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.
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 LinkMaster 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.
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 185.
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.
Page 64
Page 65
User Guide| LQ Series 4.0
l Input/Output gain: -12 to +12 dB. Default = 0.
l Port function (sets pin polarity of cable) : to Matrix/to Panel. .
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 91
7.6 IVC-32 specific port settings
Network Quality: EHX Managed/Very High (LAN)/High (WAN)/Low (internet). The
default setting is EHX Managed.
Page 65
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.
Settings available on all ports
Page 66
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 4.0
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 LinkMember units should also be given static IP addresses.
See Linking over Internet or WAN on page 60
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 67
Page 68
User Guide| LQ Series 4.0
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.
For more information, see:
Linking over Internet or WAN on page 60
Page 68
Page 69
8.4 Link-local environments
User Guide| LQ Series 4.0
8.4.1 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 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.
Page 69
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.
Page 70
User Guide| LQ Series 4.0
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.
Page 70
Page 71
9 Internet connectivity
All devices within a Link-Group must have connectivity to the Link-Master on TCP
port 80 (TCP port 433 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).
User Guide| LQ Series 4.0
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.

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 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 (433) 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 433 (https) for management. Once a LinkGroup 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
58
For more information about establishing a Link-Group using HTTPS see: Setting up
a Link-Group using HTTPS on page 78
10.3 How to use HTTPS with LQ Series units, overview
Page 73
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 74
User Guide| LQ Series 4.0
There are two main steps to establishing an encrypted connection on the
management ports of the LQ units.
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 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 4.0
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.
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
Page 75
Page 76
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
User Guide| LQ Series 4.0
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
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 and
register the LQ device.
Page 76
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.
Page 77
User Guide| LQ Series 4.0
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 4.0
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 LinkGroup 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 78
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 433 (HTTPS)
Linking (audio)
l TCP/UDP port 665 (encrypted channel)
Page 79
User Guide| LQ Series 4.0
The devices will pass management details via either port 80 or port 433 (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 LinkMaster 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.

Certification Authority (CA) options for use with LQ units on page 76
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 80
3. Install the certificate. The three certificate options are covered below, choose
a., b., or c.
Page 81
a. A certificate of your own choosing:
User Guide| LQ Series 4.0
Page 81
Page 82
b. The EasyDNS certificate:
User Guide| LQ Series 4.0
Page 82
Page 83
User Guide| LQ Series 4.0
c. The Clear-Com self-signed (default) certificate:
Page 83
4. Test the certificate by typing the HTTPS IP address into your browser URL field
in the format: HTTPS:// XX.XX.XX.XX :
Page 84
User Guide| LQ Series 4.0
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 ClearCom 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.
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.

Channels.
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 91

User Guide| LQ Series 4.0
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 4wire port (VOX) on an LQ 4W2 device that triggers the output relay on an LQ
GPIO device.
Page 91
Page 92
User Guide| LQ Series 4.0
2. Configure the output (GPO) on a port.
Page 92
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
