LifeSize Express 200 Installation Guide 3
Preparing for Installation
As you prepare to install a LifeSize video communications system, consider the physical
conditions of the room, compatibility with displays and your network configuration and
settings. LifeSize recommends you collect your network settings and system identification
information before you begin installation. Refer to “Initial Configuration” on page 5, which
explains what information you need to collect and provides space to record it.
Room Configuration
The size, shape, layout and occupancy of the room dictate where you place your video
conferencing components. For example, in a small office installation, LifeSize Focus can be
placed at one end or corner of the room, as its beam forming microphone array cancels out
echo from wall reflections behind it and picks up clear sound up to 2.7 meters (9 feet) in front
of it; in a multi-user conference room, place a LifeSize MicPod or LifeSize Phone at the
center of the participants as their detection patterns are omnidirectional.
Warning: Avoid routing cables from the codec across foot-traffic areas as tripping on
the cables can cause both personal injury and permanent damage to the connectors in
the cables and codec. If cables must cross foot-traffic areas, use some form of cable
management system or strategy to avoid the possibility of tripping.
The lighting in your environment affects image quality. The optimal lighting for LifeSize
systems is 300 to 500 LUX. If light levels are too low, consider adding artificial lighting.
Indirect light from shaded sources or reflected light from pale walls often produces excellent
results. Avoid the following:
• direct sunlight on the subject matter, the background, or the camera lens
• direct illumination of the subject matter and camera lens
• colored lighting
• harsh side lighting or strong light from above
Consult your administrator or LifeSize Partner for specific lighting requirements for your
environment.

Placement Behind a Firewall
LifeSize recommends that you place your system behind a firewall and block, at minimum,
the following ports:
• 22 (SSH)
• 23 (Telnet)
• 80 (HTTP)
• 443 (HTTPS)
If you require these ports remain open, ensure that you change the default administrator and
command line interface passwords to be very secure. For information about changing the
default administrator password, refer to the LifeSize Video Communications Systems
Administrator Guide.
For information about changing the command line interface password, refer to the LifeSize
Automation Command Line Interface document available on the Support page of
www.lifesize.com.

LifeSize Express 200 Installation Guide 5
You can also disable SSH and web access on the system by configuring preferences in the
user interface. By default, Telnet access is disabled. For more information, refer to the
LifeSize Video Communications Systems Administrator Guide.
Network Bandwidth
Poor audio and video quality may result from insufficient bandwidth on your network.
LifeSize recommends that your network be capable of at least 1 Mb/s (incoming and
outgoing) for a high definition video call. During video calls with lower bandwidths, LifeSize
systems automatically select the best resolution that can be achieved with the available
bandwidth.
Domain Name Service Server
If you intend to use domain addresses for placing calls you must configure a Domain Name
Service (DNS) server, or use a Dynamic Host Configuration Protocol (DHCP) server that
automatically sets a DNS server.
Initial Configuration
During the installation process, your LifeSize system prompts you to configure it for the first
time. LifeSize recommends that you gather all the necessary information prior to installation.
The following sections provide guidelines for collecting and a means of recording this data.
You may need to consult your network administrator for network settings and system
identification information.
Note: The initial configuration screens also appear when you perform a system reset. For
more information, refer to “Restoring Default Settings” in the LifeSize Video
Communications Systems Administrator Guide.
Language
Select the language to display in the user interface. The default is English.

6 LifeSize Express 200 Installation Guide
Administrator and User Passwords
Some functions and preferences available from the user interface are accessible only to
administrative users with a password. For security reasons, LifeSize recommends that you
change the default administrator password (1 2 3 4) during the initial configuration.
Optionally, you can set a user password to control access to user preferences that enable
the user to do the following:
• Change the appearance of the user interface.
• Specify how calls are answered.
• Configure audio settings.
• Change cameras and DVI-I input settings.
• Reboot the system.
The administrator and user passwords can contain any combination of the numbers 0-9 and
the symbols * (star) and # (pound) up to 16 characters in length.
Note: If you set a user password, you can also use the administrator password to access
user preferences.
Administrator Password: ________________________________________________
User Password: _______________________________________________________
System Identification
Information that identifies the system to users appears throughout the user interface.
Set the Location preference to your location. The default is the United States. The Time
Zone preference sets the system time that appears in the status bar on the main page of the
user interface. It defaults to Greenwich Mean Time. You must set this preference even if you
specify an NTP server during the initial configuration (refer to “Network Settings” on page 7).
The System Name, Video Number, and Voice Number appear in the user interface on the
main screen. The system name may also appear in the local and corporate directories.
LifeSize recommends that you change the default system name to one that meaningfully
identifies the system to your users.
System Name: (to identify this installation in the network): ______________________
Video Number: ________________________________________________________
Voice Number: ________________________________________________________

LifeSize Express 200 Installation Guide 7
Video and Voice Dialing Preferences
LifeSize systems support either the IP or ISDN protocol for video dialing. The default setting
for the Video Dialing preference is Auto which enables the system to determine the best
method to use to place calls.
LifeSize Express 200 supports VoIP and ISDN for voice calls. VoIP uses H.323 or SIP.
When placing a call using the Voice button on a LifeSize Phone connected to the system,
you can dial IP addresses as well as VoIP or ISDN phone numbers.
When placing a call using the remote control or using the Video button on the phone you
can dial IP addresses. This enables systems inside a corporate network without access to a
gateway to call other LifeSize systems in the network using system IP addresses.
Network Settings
By default, DHCP is enabled on LifeSize systems. If you choose Disabled for the DHCP
preference, you must enter an IP address (the locally configured IP address if not assigned
by a DHCP server), Subnet Mask (used to partition the IP address into a network and host
identifier), and Default Gateway (the IP address of the default gateway the system uses).
IP Address: ___________________________________________________________
Subnet Mask: _________________________________________________________
Default Gateway: ______________________________________________________
You can enter the Hostname of the system. If you do not have a DHCP server that
automatically sets a DNS server, you can enter the IP addresses to configure DNS Servers.
You can also define the domain names to search when resolving hostnames. DNS
translates names of network nodes into addresses; specify this preference to use DNS to
resolve the hostnames of devices to IP addresses.
Hostname: ____________________________________________________________
DNS Servers:__________________________________________________________
Name Search Domains: _________________________________________________
If you choose an option other than Auto (the default) for the Network Speed preference,
ensure that the option matches the speed and duplex configured on your network switch.
Network Speed: ________________________ Network Duplex: _________________
You can enter the hostname or IP address of a Network Time Protocol (NTP) server to set
the system date and time automatically. The LifeSize system ignores the value you specify
for the NTP Server Hostname if the DHCP preference is set to Enabled and the DHCP
server can pass an NTP server address to the LifeSize system.
Network Time Protocol (NTP): ____________________________________________

8 LifeSize Express 200 Installation Guide
Audio Preferences: Active Microphone
The default for the Active Microphone preference is Auto. The system detects attached
audio input devices and selects one to be the active microphone in the following order:
• phone
• microphone in
• camera 1
If you wish to use a device connected to line in on the codec as the active microphone, you
must choose line in manually for Active Microphone.
The Active Microphone field in the System Information page shows which device is
functioning as the active microphone. When the value is None, the No Active Microphone
indicator appears in the status bar on the main screen of the user interface indicating
that no active microphone is available. You can view the System Information page after
you install the system and complete the initial configuration. From the main screen, press
the button on the LifeSize remote control.
Note: If you choose Line In or Line In (No AEC) as the active microphone, and a device is
not connected to line in on the codec, the System Information page shows line in
as the status for Active Microphone. The No Active Microphone indicator does not
appear in the user interface.
The Microphone In (No AEC) and Line In (No AEC) options for the Active Microphone
preference are for use with a microphone that has its own acoustic echo canceller (AEC).
Audio Preferences: Active Microphone Volume
You can adjust the audio level for the active microphone by selecting Active Microphone
Volume and pressing OK on the LifeSize remote control.
Note: A built-in acoustic echo canceller and noise reducer are active when Microphone In,
Camera 1, or Line In is the active microphone. The built-in acoustic echo canceller
automatically attempts to adjust audio volume for optimum levels.

LifeSize Express 200 Installation Guide 9
An audio meter appears below Active Microphone Volume when you access the
preference. The audio meter follows the digital signal processing, Automatic Gain Control
(AGC), and volume and tone controls on the transmitted voice path as depicted in the
following illustration.
The dotted line illustrates the audio path when Microphone In (No AEC) or Line In (No AEC)
is selected as the active microphone. This mode is useful for setting up system gains but
should never be used during calls unless the installation includes audio inputs with external
AEC. Echo may occur if no AEC is employed.
If you choose LifeSize Phone as the active microphone, the Active Microphone Volume
preference is not available. The LifeSize Phone microphones adjust volume automatically.
The voice stream bypasses all processing in the LifeSize system, including the volume and
tone controls, and is fed directly into the transmitted voice path.
The audio meter displays the level of the transmitted voice in decibels (dB) root mean
square (RMS) below digital full scale (DFS). The meter is accurate to ± 1 dB. The maximum
level is 0 dB. Levels below –50 dB are not displayed, and indicate a very quiet or inactive
input. Typical levels during a call peak around –28 to –22 dB DFS. The AEC and AGC
attempt to keep the RMS transmit level below –20 dB DFS. The following images show what
appears in an audio meter at various levels.

Typical Transmit Voice Level in a Call
When setting Active Microphone Volume for LifeSize MicPod or LifeSize Focus, place
someone where a participant in a call would normally sit in the conference room and ask the
person to speak at a normal volume facing the active microphone.
Use the audio meter to visually verify that the transmit level peaks in the desired -28 to -22
dB range.
LifeSize recommends a volume setting of 5 to 8 for Active Microphone Volume for most
LifeSize MicPod applications.

LifeSize Express 200 Installation Guide 11
LifeSize recommends a volume setting of 5 to 10 for Active Microphone Volume for most
LifeSize Focus applications.
If you set Active Microphone Volume to line in when using an external mixer or amplified
microphone, follow these steps:
1. Select Line in (no AEC) for Active Microphone.
2. Position someone approximately one meter from the microphone, facing it, speaking at
a normal volume.
3. Adjust the Active Microphone Volume and the external mixer output level until the
meter peaks in the -28 to -22 dB range. LifeSize recommends you adjust the external
mixer volume so that you achieve peak levels in the -28 to -22 dB range of the audio
meter with the Active Microphone Volume control set to no less than 5 or greater than
15.
4. If the microphone or mixer you use employs an echo canceller, no further adjustments
are necessary. Otherwise, select Line In for Active Microphone. This turns on the
LifeSize system’s echo canceller, noise reduction, and automatic gain control functions.
If you do not use an echo canceller, you may experience severe echo effects.
5. After the adjustment, check that the peak levels when speaking normally one meter from
the microphone are in the -28 to -22 dB range. The AGC attempts to keep the transmit
level below -20 dB, which is the green range of the bar graph.
An audio meter is also available for the Line In Volume preference for setting an audio level
for a device connected to line in on the codec when line in is not selected as the active
microphone.
Audio Preferences: Video and Voice Call Output
If you plan to use external speakers other than LifeSize Phone for audio output in both video
and voice calls, ensure that the Video Call Audio Output and Voice Call Audio Output
preferences are set to Line Out. By default, Video Call Audio Output is set to Line Out;
Voice Call Audio Output is set to Phone. If you are using LifeSize Phone for audio, set
these preferences to Phone.
Audio Preferences: Testing Speakers
You can also test the primary output speakers for the appropriate audio level or to ensure
they are working properly. Select Auto for Primary Audio Output Test to cycle through a
test on your available speakers. The test continues until you select Off. You can also send
the tone to either the left or right channel by choosing Test Left or Test Right. The tone is
sent simultaneously to both line out and the HD video out of display 1.

Configuring Dual LifeSize MicPods
If you are using dual LifeSize MicPods, you can use the splitter cable to connect a
combination of extension cables and two LifeSize MicPods to the single LifeSize MicPod
port on your LifeSize codec for maximum omnidirectional audio coverage in large
conference rooms.
Dual LifeSize MicPod configurations are limited to two LifeSize MicPods and one splitter
cable. (You cannot use multiple splitters to connect to more than two LifeSize MicPods.)
However, you can use variations on three configurations of extension cables:
• If you connect the male end of the splitter directly to the codec, you can use none, or
one extension cable to connect a LifeSize MicPod to each of the female ends of the
splitter.
• If you use one extension cable to connect the codec to the splitter, you can use none, or
one extension cable to connect a LifeSize MicPod to each of the female ends of the
splitter.
• If you use two extension cables to connect the codec to the splitter, you must connect
both LifeSize MicPods directly to the female ends of the splitter.
If the LifeSize MicPods are installed in an area where the cord could be pulled or tripped
upon, refer to “Attaching the LifeSize MicPod Strain Relief Clip” on page 19.
Warning: Tripping on the cord can cause personal injury as well as permanent
damage to the LifeSize MicPod cord connector and the connector in the codec. LifeSize
recommends that you use the cable strain relief clip included in the LifeSize MicPod
product box as described in “Attaching the LifeSize MicPod Strain Relief Clip” on
