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:
nOne or two telepresence screens that support a 1080p60 input format
nSupported video camera
nMicrophone
nStarLeaf 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:
nCodec (with feet attached)
nAudio injector
nInstallation sheet
nRack mounting ears kit
nCables
lPower cable
lDVI-I to DVI-I cable

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:
nConnect 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
nTo 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
nUsing the supplied power cable, connect the IEC mains power connector on the rear of
the codec to the mains power.

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.
