StarLeaf installation guide, 01 April 2021 Page 5 of 34

About the codec
StarLeaf Pronto
StarLeaf Pronto allows users to meet and share in an instant. When you connect Pronto to
your laptop, your screen and audio are shared with the room so that you are ready to
present immediately. Your StarLeaf meetings are also synchronized with the room,
allowing you to join with one touch.
Go to Installing Pronto Cable USB for more information.
DVI-I cable
Connect the DVI-I to DVI-I cable to Computer-In DVI-I on the rear of the codec. For the
convenience of the Group Telepresence users, leave the other end of the cable on the
meeting room table. This allows users to connect a laptop to the Group Telepresence
system when they need to do so. The Group Telepresence system includes a selection of
adaptors to be used with the DVI-I to DVI-I cable where the video output of a PCis other
than DVI-I (for example, VGA, HDMI, DVI-D).

3.5mm audio connector pinout
All StarLeaf room systems use a standard 3.5mm connector:
Left signal = tip
Right signal = middle
Ground = back
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 at https://www.soundcontrol.net/solutions/#

Connecting cables to the codec
StarLeaf installation guide, 01 April 2021 Page 10 of 34

How to install GT Mini 3330
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:
The touchscreen controller must connect directly to the codec; do not connect the
touchscreen controller to the codec using a switch.
Note: If you are using the StarLeaf Conference Phone 2220, refer to .
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. (Note: on older systems, if you have only one screen,
connect it to the port labeled: HDMI 2.)
4. Connect the camera. One of:
lPTZ camera: connect the camera to Camera Control and to Camera In and then
connect power to the camera
lWebcam: connect the camera to the lower of the two USB ports
5. 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
and to Audio settings for Group Telepresence (p19)).
6. Using the supplied AC/DC adaptor and power cable, connect power to the codec.

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 StarLeaf
To connect your room system to StarLeaf you must provision it through the Portal as
described in the video and instructions below.
Either you or your reseller can register the room system using the StarLeaf Portal. To do this:
