DIGITUS Wireless HDMI Transmitter Unit for DS-55319 (additional unit)

The Digitus Click & Present Mini (DS-55319) is a compact wireless AV transmitter and receiver system that wirelessly transmits HDMI video and audio signals in Full HD (1920 x 1080) up to 50 m in an unobstructed line of sight. The set supports connection of multiple transmitters and is intended for meeting and conference rooms where quick, cable-free content sharing is required.

Advantages

The system supports up to 16 transmitters connected to a single receiver, allows fast switching between sources with a button press, and enables screen sharing from smartphones and tablets using native OS screen sync (iOS, iPadOS, Android). It is plug & play for simple installation and operation, has a compact form factor for flexible placement, and supports common desktop operating systems (Windows, macOS) as well as mobile platforms. For stable power supply, Micro‑USB cables are recommended though the transmitter can draw power via the HDMI port if the source provides more than 500 mA.

How to use

Connect the receiver to a display via HDMI and power both transmitter and receiver using the included Micro‑USB cables (recommended). Plug the transmitter into the source device’s HDMI port or use the appropriate adapter; if the HDMI source provides more than 500 mA the transmitter can draw power from the HDMI connection, but Micro‑USB power is advised for reliable operation. Select the desired transmitter at the receiver by pressing the source-selection button to start displaying the content. For mobile devices use the device’s built-in screen sync (no additional app required).

Recommendations

For stable wireless performance keep a clear line of sight between transmitter and receiver and avoid placing them behind large obstacles. Use Micro‑USB power for both TX and RX to ensure reliable operation and add DS-55320 transmitters if you need more sources.
