TrueConf Group Guide

# Hardware Setup

Select the device models in the sections listed below. Their names will appear in the list with a label in square brackets, for example, [USB] TrueConf.

# Screens

The standard version of TrueConf Group supports dual monitor output via HDMI and DisplayPort connections. To configure them, go to Settings → Devices → Monitor.

If both monitors are connected, select the display where the main menu of the terminal should be shown from the dropdown list Monitor 1 (Primary).

If necessary, you can adjust the resolution of the primary and secondary monitors (in the Monitor 2 section) using the appropriate options. To select the monitor operating mode (graphic resolution and frame rate), use the HDMI resolution option. This setting can help resolve potential compatibility issues when connecting two monitors with different resolutions. In modes up to UltraHD, background animation on the main screen and background blur in modal windows function in the main menu.

In the Content dropdown list, select what should be displayed on the additional monitor:

  • Auto – displays a presentation in the active conference, or your own video if no presentation is available;

  • Presentation: Shared content

  • Local video – the image from the main terminal camera or a screensaver if the camera is turned off;

  • Copy primary: Copy the feed from the primary screen.

Additionally, using the Detect video outputs feature, you can display the names of the video outputs connected to the terminal on the attached displays, such as HDMI-1 and HDMI-2, indicating the primary and secondary monitors, respectively.

The Monitor test option allows you to calibrate the colors of connected screens using a special image. The calibration image is displayed only on the primary monitor.

# Video capture

Go to Settings → Devices → Camera to configure the PTZ camera or other video capture sources:

  1. Select the desired device from the Primary camera list, which may include:

    • USB-connected camera;

    • camera connected via HDMI;

    • NDI streams – all found on the local network are displayed (i.e., the same ones as in the Contacts → NDI section);

    • RTSP stream - displays the contact names from the terminal's local address book that have an RTSP call string specified. If multiple RTSP addresses are specified for a contact, the image is captured from the first one on the list. Therefore, to display an image from an RTSP stream instead of a camera, you need to:

      1. create a contact using the RTSP dial string;

1. create a camera from this contact, <interface ru="{Настройки} {Устройства} {Управление устройствами} {Добавить устройство из адресной книги (RTSP, VNC)}" en="{Settings} {Devices} {Device management} {Add device from address book (RTSP,VNC)}"/>;

1. select the created device from the contact as the main camera or shared content.
    1. VNC stream – the names of contacts from the address book are displayed if they have a VNC call string. The rendering rules are similar to the rules for RTSP.

  2. If a USB-connected camera is selected, you can:

  • adjust the brightness, contrast, saturation, and other settings of the captured video. For a detailed description of all parameters, refer to the user documentation on the TrueConf Group.

  • Specify the camera Definition in use.

3. If a PTZ camera is being used, navigate to Device management and click /docs/group/media/gui/edit/en.png. A window will open where you can:

/docs/group/media/control_panel/device_setting/en.png

  • change the display name of the camera;

  • set the image resolution;

  • select the PTZ protocol for controlling the camera position based on the connection:

    • control via RS-232 (Visca, Pelco-P, Pelco-D);

    • control via LAN (Visca-IP, NDI);

    • control via USB (UVC).

  • select the serial port (the HARDWARE port is built into the terminal);

  • select the VISCA address (the camera's logical address for control via the RS232 port).

4. If controlling the camera via the VISCA, PELCO-P, or PELCO-D protocol, specify the IP address.

5. The terminal supports controlling a camera connected to the local network using the VISCA over IP protocol. To send commands to such a camera, specify its IP address in the VISCA IP field, with port 52381 used by default.

You can connect additional USB to RS-232 adapters to the TrueConf Group terminal to control multiple cameras simultaneously using VISCA, PELCO-D, and PELCO-P protocols. They will be displayed in the ports dropdown list.

# Microphone

Go to Settings → Devices → Audio → Audio settings.

In the Microphone dropdown list, select the interface to which the microphone is connected. Say a few words, and if the equipment is functioning and recognized by the terminal, the indicator at the top of the menu will vary according to the volume of your voice.

To test the microphone, click Start test. Check the volume and playback quality of the incoming audio signal through the terminal speakers. If the volume settings are not satisfactory (for example, if the sound is too low), adjust the microphone volume using the slider at the top of the web panel screen.

Complete speakerphones come with a built-in echo canceller, so the software echo cancellation mode should be set to Disabled in the settings when using them. Enabling software echo cancellation on the terminal will be effective when outputting sound to a TV or other external audio devices.

To eliminate echo, select the appropriate Echo cancellation mode:

  • 50 Hz filter only – eliminates low-frequency sounds, such as stomping and banging on the table;

  • Half-duplex – effective when the microphone is very close to the speaker;

  • Full-Duplex is the primary operating mode.

  • Custom – includes parameters optimized for a specific device.

Enable Microphone gain control for automatic microphone sensitivity adjustment. This setting is available if one of the echo cancellation modes is selected.

When using microphone input gain (AGC), various noise or sound distortions may occur along with the volume. We recommend using this setting only when absolutely necessary.

If there is background noise in the room where TrueConf Group is used, activate Noise suppression to eliminate unwanted sounds and improve speech clarity. When using a USB speakerphone, both the echo canceller and noise suppression should be turned off, while they should be enabled when using an analog microphone. If a speakerphone is used for audio capture and an HDMI-connected device (such as TV panel or monitor speakers) is used for output, the hardware echo canceller will not function, and software-based echo cancellation should be used instead.

Audio settings (noise cancellation, echo cancellation, and volume) are saved for each device individually.

When the Yamaha YVC-1000 speakerphone is used, it needs to be connected to the endpoint only via the USB 3.1 port for proper configuration.

# Speakers

In the Settings → Devices → Audio section, select a speaker under Speakers.

You can select the output device HDMI Out, allowing sound to be output to the built-in speakers of the connected video output device (monitor or TV).

To test sound playback, click Start test. If the equipment is connected successfully, you should hear a short musical clip.

# Tablet

In certain configurations, a desktop tablet is provided with TrueConf Group. The device comes with pre-installed software and is usually already set up for automatic connection. In situations such as tablet replacement, additional steps may be required to link the tablet to the terminal.

To connect a tablet:

  1. Connect the tablet to the power supply using the included PoE injector, then use the USB–RJ-45 adapter to connect it to the terminal. A detailed connection diagram is provided here.

  2. On the tablet screen, select your terminal. The TrueConf Group address will appear as: "terminal_address":1337/tablet.

  3. When connecting the tablet for the first time, you need to enter the code displayed on the terminal screen.

/docs/group/media/tablet_code/en.png

4. After authentication, the tablet displays an interface adapted for touch control.

On the terminal, navigate to the Settings → Devices → Touchscreen controller section and enable the Prevent connection of devices to the endpoint setting. This configuration will help prevent unwanted connections.

# Managing Connected Tablets

To manage tablets connected to the terminal, go to the Settings → Devices → Touchscreen controller section.

/docs/group/media/tablets_settings/en.png

Here you can:

  • Prevent connection of devices to the endpoint – this setting only applies to new devices. You can activate this option after connecting all necessary tablets to avoid unauthorized connections.

  • View the list of Connected devices to see all connected tablets. The displayed information includes the device name and the last time it connected to the terminal. To disconnect a tablet and reset its pairing, click Forget device.

  • View the list of Blocked devices. To block a device, click Block device during connection, on the screen with the one-time code.
