TrueConf Group Guide

# Hardware Setup

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

# Screens

The standard version of TrueConf Group supports output to two monitors simultaneously via HDMI and DisplayPort. To configure them, go to the section.

If both monitors are connected, select the display on which the terminal's main menu should appear from the dropdown list Monitor 1 (Primary).

If needed, you can adjust the resolution of the primary and secondary monitors (located in the Monitor 2) using the appropriate settings. To select the monitor's operating mode (including graphical resolution and frame rate), use the HDMI mode option. This setting can help address 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 are enabled in the main menu.

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

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

  • Presentation: Shared content

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

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

Additionally, using the Test video outputs function, you can display the names of the video outputs, such as HDMI-1 and HDMI-2, on the connected terminal displays, 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 main monitor.

# Video capture

Go to the section and configure the PTZ camera or other video capture devices:

  1. Select the desired device from the Primary camera list, which could be:

    • USB-connected camera;

    • camera connected via HDMI;

    • NDI stream – all streams found in the local network are displayed (i.e., the same streams that are available in the Address book → NDI section);

    • RTSP stream – displays the names of contacts 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 in the list. Therefore, to display an image from an RTSP stream instead of a camera, you need to:

      1. create a contact with an RTSP call string;

1. create a camera from this contact, <interface ru="{Настройки} {Устройства} {Камера} {Управление устройствами} {Добавить устройство из адресной книги (RTSP, VNC)}" en=""/>;

1. select the device created 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, please refer to the user documentation on the TrueConf Group.

  • specify the camera Resolution you are using.

3. If a PTZ camera is being used, go 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 camera display name;

  • set the image resolution;

  • select the PTZ protocol to control the camera position depending 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 (camera's logical address for control via the RS232 port).

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

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

Additional USB to RS-232 adapters can be connected to the TrueConf Group terminal to control multiple cameras simultaneously using VISCA, PELCO-D, and PELCO-P protocols. These will appear in the port drop-down list.

# Microphone

Go to Settings → Devices → Audio → Audio settings.

In the Input 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 quality of the incoming audio signal through the terminal speakers. If the volume settings are not satisfactory (for example, the sound is too weak), adjust the microphone volume using the slider at the top of the web panel screen.

Built-in speakerphones come with an integrated echo canceller. Therefore, when using them, you should set the software echo cancellation mode to Disabled in the settings. Enabling software echo cancellation on the terminal will work effectively when outputting sound to a TV or other external audio devices.

To eliminate echo, select the appropriate Echo cancellation mode:

  • Only 50Hz filter – removes low-frequency noises such as stomping and table thumping;

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

  • Duplex is the primary operating mode.

  • Custom – includes parameters optimized for a specific device.

Enable Microphone boost to automatically adjust the microphone sensitivity. This setting is available if one of the echo cancellation modes is selected.

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

Additionally, if there is background noise in the room where TrueConf Group is being used, activate Noise reduction to eliminate unwanted sounds and improve speech clarity. When using a USB speakerphone, both the echo canceller and noise reduction should be disabled; when using an analog microphone, they should be enabled. If a speakerphone is used for sound 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 a software-based solution 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 the speaker under Output.

You can select the HDMI Out output device, which will allow audio to be played through 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 piece.

# Tablet

In some configurations, TrueConf Group provides a desktop tablet. The device comes with pre-installed software and is usually already configured and connects automatically. In cases such as tablet replacement, additional actions may be required to link the tablet to the terminal.

To connect a tablet:

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

  2. On your tablet screen, select your terminal. The address TrueConf Group 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 authorization, the tablet displays an interface adapted for touch control.

On the terminal, navigate to the section and enable the setting. This setting will prevent unwanted connections.

# Managing Connected Tablets

To manage the tablets connected to the terminal, go to the section.

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

Here you can:

  • Prohibit device connection to the terminal – this setting applies only to new devices. You can activate this option after connecting all necessary tablets to prevent unauthorized connections.

  • View the list of Connected Devices – a list of all connected tablets is displayed. The displayed information includes the device name and the last connection time to the terminal. To disconnect the tablet and reset its pairing, click Forget Device.

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