telepresence screen display outputs, ensure you use the correct gauge of HDMI/DVI
cable. For short cable lengths of up to 5m (17 feet), use 28AWG or thicker core. For longer
lengths, use 24AWG or thicker. StarLeaf does not support the use of HDMI or DVI cables of
longer than 15m (49 feet) with the codec.

Group Telepresence 3351 InstallationGuide, February02, 2017 Page 5 of 28

About the codec

Extending the camera cables

StarLeaf room systems that use a PTZ camera are provided with camera connection
cables of 5m in length. If you need to install the camera further than 5m from the room
system, you must extend those cables.

You can extend those cables using a third-party product called an extender. This product
effectively carries the media and camera-control signals across a cat 6 Ethernet cable.

StarLeaf has partnered with Sound Control Technologies to provide this solution which is
available from them at http://www.soundcontrol.net/solutions/#

Group Telepresence 3351 InstallationGuide, February02, 2017 Page 6 of 28

About the touchscreen controller

About the touchscreen controller

Every Group Telepresence system comes with a touchscreen controller: the StarLeaf
Touch 2035. You use the touchscreen controller as the means for making and controlling
video calls with Group Telepresence. Through the touchscreen controller, you can access
the directory and contacts. You can use the touchscreen controller to create ad hoc
conferences, and to add and remove participants.

How to install Group Telepresence 3351

How to install Group Telepresence 3351

Before installing a StarLeaf product, read the safety information at

www.starleaf.com/safety.

Pre-requisites

Before installing the room system, ensure you have the following:

n A StarLeaf Cloud account
n One or two telepresence screens that support a 1080p60 input format (use televisions

that have an audio-output capability, or alternatively, you can connect loud speakers
to the codec). If the televisions have an option to enable "Game Mode" or "PC Mode",
then do so as this reduces media processing delays and improves video experience

n Supported video camera
n Network connection routable to the public Internet
n Microphone
n StarLeaf touchscreen controller (not installed)

Unpack the room system. The package contents is:

n Codec (with feet attached)
n Installation sheet
n Rack mounting ears kit
n Cables

l Power cable
l HDMI to HDMI cables (two) (connects codec to screens)
l DVI-I to DVI-I cable and 3.5mm jack to RCA (connects codec to PC video and

audio)

l Network cable

n Adaptors for the codec-to-PC cable

l DVI-I to HDMI
l DVI-I to VGA
l DVI-I to DVI-D

Positioning the codec

1. Ensure you have chosen an appropriate installation site:

l The codec must be accessible with all cables easily connected
l You must provide ventilation for the codec; leave a space of at least 10cm (4

inches) behind, in front, and to the left and right of the codec

l Ensure that the power switch is easily accessible; the power switch is the main

disconnect device for the codec

l Use a grounded AC power outlet for the codec

2. Rack mount the unit or place on firm horizontal surface. The codec is 2U high (with
removable feet detached) and fits in most standard 19-inch racks.

Connecting cables to the codec

1. Using an Ethernet cable, connect the StarLeaf Controller port on the codec to the
network port (PoE) on the rear of the touchscreen controller. The network port on the
touchscreen controller is marked with this symbol:

Group Telepresence 3351 InstallationGuide, February02, 2017 Page 8 of 28

How to install Group Telepresence 3351

Note: The touchscreen controller must connect directly to the codec; do not
connect the touchscreen controller via a switch to the codec.

Note: If you are using the StarLeaf Conference Phone 2220, refer to Installing the

Conference Phone 2220 (p21).

2. Using an Ethernet cable, connect the Network port on the rear of the codec to an
Ethernet switch in your network. The Ethernet port is a 10/100/1000 Mbit/s auto-sensing
port and is set to ‘auto’ by default.

Note: In all cases, the speed and duplex settings at either end of the connection must
be identical. Using non-matching settings causes severe packet loss.

To configure the network speed and duplex settings of the codec’s Network port: on
the touchscreen controller that you have connected to the codec, go to settings >

networking > network port speed.

3.

Connect one telepresence screen to Video Out A. If you have a second telepresence
screen, connect it to Video Out B.

4.

Connect the camera to Camera 1 and to Camera Control 1. (You can connect up to
two additional cameras, which are switchable using the Camera control tab on the
home screen of the touchscreen controller.)

5. Connect power to the camera.

6.

Connect the microphone to Microphone 1. (Note that you can, instead, use a
microphone connected to Audio In. If you do so, refer to Using the line-in connector

(p12) and to Audio settings for Group Telepresence (p16))

7. Using the supplied AC/DC adaptor and power cable, connect power to the codec.
The power LED on the side of the codec lights.

How to install Group Telepresence 3351

Mounting the camera

StarLeaf recommends that when you mount the camera, you place it at the top of the
screen, as opposed to the base. This makes it easier for you to see the participants on the
screen while still appearing to make eye contact.

If you have a dual-screen system, ensure that the camera is mounted on the screen that
will display the view of the main video (telepresence screen 1).

Connecting to the Cloud

About the camera

About the camera

Before you install the camera, read the safety information in the documentation that
accompanies the camera.

For PTZ cameras, the required camera settings vary from camera to camera. Ensure the
camera is using the correct settings. You must refer to the documentation that
accompanies the camera to find out the settings for that particular camera.

PTZ cameras are supplied without a remote control as you control the camera with the
StarLeaf Group Telepresence system.

Camera control for the PTZ camera

The Camera Control tab on the home screen provides you with controls for the PTZ
camera.

Camera control on the Group Telepresence 3351:

The near-end camera control allows you to pan, tilt, and zoom your camera. This control is
available both in a call and before you make a call. If the far end is using a PTZ camera,
you might be able to control it yourself using the far-end camera (their camera) control.

Camera presets are pre-defined camera positions. For example, a pre-defined position
that points the camera at the whiteboard, or that changes the camera to a wide-angled
view. Select the position you require from the touchscreen controller.

If you have more than one camera attached to the Group Telepresence 3351, the active
camera selector allows you to select which camera you want to use.

Camera presets

Camera presets allow you to save up to five pre-defined camera positions. Users can then
select these positions from the touchscreen controller.

To create camera presets:

1. Use the touchscreen controller to move the camera to the required position.

2.

On the StarLeaf Portal, find the Edit room system page for this meeting room system
and open the Audio and video settings.
