Configuring GTm 5250
Installing GTm 5250Last updated July 19, 2017
The following instructions are for setting up the GTm 5250.
- On the GTm 5250 touchscreen controller, press the settings button to view settings and the IP address.
- In a web browser, navigate to the IP address of the GTm 5250.
- Select a configuration. If you are using Maestro, choose Hosted or On-premise, or choose Demo/Unmanaged if you will not use Maestro to manage the GTm. If you choose Demo/Unmanaged, you configure the GTm using its web interface; the settings are available under Status. If you choose Maestro, you will manage the GTm using Maestro and you will only configure proxy settings, if required, through the web interface.
- Network configuration
- : If there is a proxy server for your deployment, you need to configure the details of that for the GTm. Note that this is the same configuration as you would use for a PC running a Skype for Business/Lync client in the same location on your network. To configure the proxy server settings, go to
For more information about configuring the GTm through the Maestro management platform, start here: Introduction to Maestro.
For more information about using GTm in demo/unmanaged mode, refer to Demo/Unmanaged GTm configuration.
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 displays 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.
When the GTm goes into standby mode, the screens darken, the microphone is disabled, and the camera turns away from the room. The touchscreen controller does not dim unless it is during out-of-hours.
The GTm does not go into this state if an active content source is connected. If you touch the controller or connect a content source, the GTm comes out of standby mode.
