About monitors when you have a 
Codec C60
Connecting the main monitor
The main monitor can be connected to video output HDMI 1 
(the default connector for the main monitor) or DVI-I 2.
The codec will read the native resolution of the monitor and 
output this if possible. Typically this will give the best possible 
picture for the connected monitor. If auto fails, you will have 
to select the resolution manually using the Video > Output > 
HDMI 1 > Resolution and Video > Output > DVI 2 > Resolution 
settings.
Connecting to HDMI 1
When connecting the main monitor to HDMI 1 the menu, 
icons and other information on screen (OSD - on screen 
display) will be displayed on the monitor automatically. This is 
because HDMI 1 is the default video output of the codec.
Connecting to DVI-I 2
When connecting the main monitor to the DVI–I 2 output, 
the menus, icons and other information are not automatically 
displayed on screen. You must move the OSD to the chosen 
output.
Dual monitors
When you want to run a dual monitor setup, connect the main 
monitor to video output HDMI 1 and the second monitor to 
video output DVI-I 2 on the codec.
Dual monitor configuration
To distribute the layout on the two monitors, go to 
Advanced configuration (menu on screen) or open the 
System Configuration page (web interface). Then go to 
Video > Monitors  and choose Dual .

Connecting the Cisco 
TelePresence Touch 8” controller
The Cisco TelePresence Touch 8” controller is an alternative 
to the remote control and on screen menus.
When a Touch controller is connected to the codec, the 
remote control cannot be used. You have to disconnect 
(unpair) the Touch controller in order to to use the remote 
control.
Touch 8” can can be used with a C Series codec running 
software version TC4.1 or later.
Connecting the Touch controller 
There are two options how to connect the Touch controller to 
the codec. In both cases the connection is via the provided 
power adapter, as illustrated above.A.
 
C
 onnecting the Touch controller to the codec via LAN.
To enable this mode of operation make sure that the 
NetworkServices > SSH > Mode
* setting is turned On . 
The process of associating the Touch controller to the 
codec is called paring. The codec is signalling that it is 
available for pairing for 30 minutes after it is switched on.
We recommend that the Touch controller and video 
system is kept on the same subnet.
B.
 
C
 onnecting the Touch controller directly to the codec’s 
second Ethernet port.
To enable this mode of operation use the remote control 
and navigate to Home > Settings > Administrator settings 
> Pairing > Direct pairing  and choose On. 
Alternatively, set the NetworkPort 2 > Mode
*  setting to 
DirectPairing .
Restart the codec for the change to take effect. Touch controller set-up 
Once the Touch controller is connected to power, the set-up 
procedure begins. Follow the instructions on screen.
If you have connected the unit to the codec via LAN, you 
have to choose which codec to pair with. If the codec is 
not in the list of available codecs displayed on the Touch 
controller, you can choose a codec manually by entering 
its IP address.
If the Touch controller needs software upgrade, new software 
will be downloaded from the codec and installed on the unit 
automatically as part of the set-up procedure. The Touch 
controller restarts after the upgrade.
You can verify that the Touch controller is successfully paired 
to the codec by checking that the codec address is displayed 
in the top banner.
If you want more details on Touch installation, please read the 
Cisco TelePresence Touch 8 inch Installation Guide , which is 
available on the Cisco web site.
* You will find this setting in the Advanced Configuration on-screen menu (remote control) or in the System Configuration page on the web interface.

Optimal definition profiles
Under ideal lighting conditions the bandwidth (call rate) 
requirements can be substantially reduced. 
The optimal definition profile should reflect the lighting 
conditions in your room and the quality of the video input 
(camera); the better the lighting conditions and video input, 
the higher the profile. Then, in good lighting conditions, the 
video encoder will provide better quality (higher resolution or 
frame rate) for a given call rate.
In general, we recommend the optimal definition profile 
set to Normal. However, if lighting conditions are good we 
recommend that you test the endpoint on the various Optimal 
Definition Profile settings before deciding on a profile.
Go to System Configuration on the web interface and 
navigate to Video > Input > Source [1..n] > OptimalDefinition > 
Profile to choose the preferred optimal definition profile.
You can set a resolution threshold to determine when to allow 
sending video at 60 fps. For all resolutions lower than this 
threshold, the maximum transmitted frame rate will be 30 fps; 
for higher resolutions, 60 fps will be possible if the available 
bandwidth is adequate.
Go to System Configuration on the web interface and 
navigate to Video > Input > Source [1..n] > OptimalDefinition > 
Threshold60fps to set the threshold.
The video input quality settings must be set to Motion for the 
optimal definition settings to take any effect. With the video 
input quality set to Sharpness, the endpoint will transmit the 
highest resolution possible, regardless of frame rate. 
Go to System Configuration on the web interface and 
navigate to Video > Input > Source [1..n] > Quality to set the 
video quality parameter to Motion.

Requirement for speaker 
systems connected to a Cisco 
TelePresence C Series codec
Cisco has put in a lot of effort to minimize the camera to 
screen delay on our TelePresence endpoints.
New consumer T Vs are usually equipped with “Motion Flow” 
or similar technology to insert new video frames between 
standard frames to create smoother images. This processing 
takes time and to maintain lip synchronization, the T V will 
delay the audio so that the audio and video arrives at the 
same time. 
The echo canceller in the Cisco endpoints can handle such 
delay up to 30
 
m
 s. Many consumer T Vs are not made for 
real time video communication and may introduce more than 
30
 
m
 s of delay. 
If you use such a T V together with a C Series codec it is 
recommended that you turn off “Motion Flow”, “Natural 
Motion” or any other video processing that introduces 
additional delay. 
Some consumer T Vs also support advanced audio 
processing like “Virtual Surround” effects and “Dynamic 
Compression” to improve the T V experience. Such 
processing will make any acoustic echo canceller malfunction 
and should hence be switched off.
Some monitors are equipped with a setting called ‘Game 
Mode’. This mode is specifically designed to help reduce the 
response time and will usually help to reduce the delay.

faceFactory resetting 
If there is a severe problem with the video system, resetting it 
to its default factory settings should be the last resort.
Always consider reverting to the previously used software 
version before performing a factory reset. In many situations 
this will recover the system. Note that both the current and 
the previous software images reside on the system. Read 
about software swapping in the ► System recovery  section.
We recommend that you use either a Touch controller or the 
web interface to factory reset the system. If these interfaces 
are not available, you can connect to the system’s standard 
serial interface and issue a factory reset command.
The remote control and on-screen menu do not give access 
to factory reset.
When factory resetting the video system the following 
happens:  •
