Installing GTm 5250

Installing GTm 5250

Before installing the StarLeaf GTm 5250, read the safety information at GTm 5250 safety

and compliance.

Pre-requisites

Before installing the GTm 5250, ensure you have the following:

n One or two telepresence screens that support a 1080p60 input format
n Supported video camera
n Microphone
n StarLeaf touchscreen controller

Note: If you are not using a separate audio system, ensure that you use televisions that
have an audio-output capability. In this case, you will also need to use the supplied audio
injector. For more information, refer to Using the audio injector (p15).

Unpack the GTm 5250. The package contents is:

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

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

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 Use a grounded AC power outlet for the codec

2. Rack mount the unit or place on firm horizontal surface. The codec is 1.5 U high (with
removable feet detached) and fits in most standard 19-inch racks.

Installing GTm 5250

Connecting network cables to the codec

1.

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

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.

Note: By default, the GTm 5250 will use DHCP to acquire an IP address. If necessary, you

can configure the GTm 5250 with a static IP address, to do so:
On the touchscreen controller that you have connected to the codec, go to settings >

networking, switch off DHCP and edit the IP address, netmask, gateway, and nameserver

fields.

Connecting the camera and microphone

1.

Connect the PTZ camera: connect the camera to Camera Inwith the camera control
cable and the camera video input cable and then connect power to the camera.

2.

Connect the microphone to Microphone In. Note that if required, you can connect
third-party microphones to either the XLR connectors or the Line-In connector. In this
case, you will need to configure the audio inputs from the web user interface (see

Audio configuration (p11))

Connecting screens and loudspeakers

On the GTm 5250, the audio emits from the audio-out connector on the rear of the
codec. Either:

n

Connect the Line out connector on the rear of the codec to amplifier and
loudspeakers. Connect one telepresence screen to Video Out HDMI 1. If you have a
second telepresence screen, connect it to Video Out HDMI 2.

or

n To send the audio over HDMI to the loudspeakers of the screen, use the supplied audio

injector as shown in Using the audio injector (p15) to connect screen 1 to the codec. If
you have a second telepresence screen, connect it to Video Out HDMI 2.

Connecting power

n Using the supplied power cable, connect the IEC mains power connector on the rear of

the codec to the mains power.

Allowing users to connect a laptop or other digital
sources to the GTm 5250

Connect the DVI-I to DVI-I cable to Computer In 2 on the rear of the codec. For the
convenience of the GTm 5250 users, leave the other end of the cable on the meeting
room table. This allows users to connect a laptop to the GTm 5250 when they need to do
so. The GTm 5250 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).

Additionally, you can connect an HDMI source to Computer In 1 on the rear of the codec.
This can be useful where you have a permanent digital source that you want to connect
to the GTm, for example an Apple TVor whiteboard.

When users are in a meeting, they can select to share content using the touchscreen
controller. If more than one source is connected, the GTm 5250 will display content from
the most-recently connected source.

Connect PC audio out (or indeed another audio source) to the audio line-in on the rear of
the codec to send PC audio to the speakers at the far end of the call.
