4. Installation

This section gives an overview of the ways to install and connect the base unit.

4.1 Installation methods for the base unit

The base unit can be installed either by table mounting or wall mounting in a meeting room.

The articulated antennas are rotatable for better signal.

Attention: For optimal performance, install the base unit close to the display and avoid obstacles between the base unit and dongles.

Required tools

• A drill (type of drill depends on the type of wall)
• 2 mounting screws (mounting screws are not included in the package) (between 6 and 8 mm)

How to install

1. Drill two holes in the wall.
2. Insert 2 flat screws into the 2 holes and fasten.
3. At the bottom of the base unit, plug 2 flat screws into 2 holes of its smallest diameter to fasten.

Note: Mounting screws are not included in the box. The type of screws depends on the type of wall (stone, wood, plasterboard, ...) the base unit is mounted to. Make sure the head of the screw is not larger than the hole at the bottom of the base unit.

4. Place the base unit on the wall and fix it with the 2 screws.

Antenna placement rules

• The antennas should be oriented vertically, perpendicular to the ceiling and parallel to the walls.
• The antennas should be installed far enough (at least 50cm/1.6ft) from metallic surfaces to avoid reflections and far enough (at least 1m/3.3ft) from other radio equipment that operates in the same frequency range, e.g., other Wi-Fi access points, cordless telephone, microwave ovens. It is also better to install antennas at least 15 cm (6 inches) from concrete walls.
• The best situation is a direct line of sight between antennas and transmitters. Any obstruction can cause the signal to follow a longer propagation path, which may result in performance degradation.
• Due to the radio pattern of the dipole antennas, the antennas should not be placed just above the position of the user. The advised position for the antennas is at the side of the meeting room.

4.2 Power Connection

The base unit can be powered by external power adapters.

How to connect the external power adapter

1. Connect the power adapter with the power lead and plug it into the power input of the base unit.
2. Choose the appropriate power plug (UK, or EU) to be installed on the power lead.
3. Plug the power lead into the wall outlet.

4.3 Video Connection

1. Connect the HDMI Output of the base unit to a 4K or Full-HD display by a HDMI cable.
2. Connect the HDMI Input of the base unit to a 4K or Full-HD video source such as a media player or PC by a HDMI cable.
3. Connect the power adapter to the base unit DC power socket, connect the power plug to an outlet and switch the base unit on.
4. The system will then display the home page and the user can switch the input signal to the HDMI input with the 'Signal source' option.

Note: TP-P900 has duplicate HDMI outputs that can be connected to two separate screens.

4.4 Audio Connection

The base unit can transmit the audio output of the PC/Mac, re-direct and send it with the video signal. The audio will be output at line levels from the mini jack socket 3.5mm connector and via the HDMI output connectors simultaneously.

It's up to the user to decide whether to send the audio signal together with the video signal.

How to connect separate audio

1. Connect an audio cable with a mini jack socket 3.5mm connector into the audio port of the base unit.
2. Connect the other side to the sound system of the meeting room.

PC/Mac Sound

By default, the internal speaker of PC/Mac will be muted, and the audio will be routed to the base unit after PC/Mac successfully mirrors the desktop to the main screen, which is to avoid repeated audio. When sharing is terminated, the local speaker will return to previous status and the volume on PC/Mac can be adjusted.

4.5 LAN/Wi-Fi connection

The base unit can be connected to a local network or directly to a PC/Mac.

1. Connect an Ethernet cable with an RJ45 connector into the LAN port of the base unit.
2. Connect the other side to LAN.
3. Configure network settings in the base unit and connect it to any available Wi-Fi point.

LAN/Wi-Fi connection can be used for:

• Network integration of the base unit in a guest or company network.

4.6 Use of USB devices

USB control

A USB mouse or touch screen can be connected to the base unit.

USB mouse

• Single click to select.
• Right-click to return.

Touch screen

• Click to select.

External USB Devices over Wi-Fi Sharing

TP-P900 supports USB Camera and USB speakerphone over Wi-Fi sharing.

There are 2 USB ports in the rear panel of TP-P900 for connecting external USB devices such as microphones and cameras, to start meetings with video conference software like Teams and Zoom.

1. Make sure the room USB peripherals and display are well connected with TP-P900 with cables.
2. Make sure that the PC/Mac is well connected with the base unit by the application.
3. Launch any VC application such as Zoom from desktop and choose:
   Settings>Video>Camera>TranScreen Camera
   Settings>Audio
   For Speaker, select ‘Transcreen Audio’
   For Microphone, select ‘Transcreen Audio’
4. Click the 'Sharing Devices' button in the application and then click ‘Open Camera’ in the application.

Note: This function only works when the base unit and the PC are under the same network and connected via the application.

5. Quick Start

5.1 Mobile device: Wireless Connection

1. Connect the mobile device to the base unit via WiFi and download ‘transcreen.app' from Seada (https://seada.co.uk/downloads/) or type in ‘transcreen.app' in any browser and download the application.

3. After pairing is completed, a message will show ‘Paired successfully' on the home page. The dongle can then be unplugged and connected to PC/Mac for use.

If the WiFi setting is changed or the firmware of the base unit has been updated, all dongles must be paired again. One dongle can only be paired with a single base unit at a time, and the dongle will always connect to the last base unit it was paired with.

Wireless dongle Pairing: TP-P900 supports wireless dongle pairing: (1) Plug the dongle into PC/Laptop; (2) Ensure that the PC/Laptop is connected to the same network as TP-P900; (3) Right-click the status icon and select Pairing Tool -> Wireless Pairing/Router Pairing; and (4) User can then remotely pair dongles to units by entering the IP address of the unit or Wi-Fi name and password of the unit.

5.3 Mirroring

5.3.1 Windows PC/Mac with application
