Important Safety Instructions
Please read the supplied safety instruction document before using the product and keep it available for future reference.
Introduction
Lightware’s universal switcher enhances and extends the possibilities of a meeting room and allows meeting participants to easily use their own devices such as laptops. UCX-H20 series models offer 4K signal switching with numerous control interfaces (secure Ethernet, OCS sensor, GPIO, Audio, and RS-232 options). The device is the right choice for customers who need cost-effective 4×3 and 4×1 HDMI-only switchers with audio de-embedding, GPIO, Ethernet, and RS-232 but without USB transmission.

Connecting Steps (example for UCX-4×3-H20)
HDMI Connect an HDMI source (e.g. BYOD laptop or room PC) to the HDMI input port.CATx Connect the Ethernet port to a Local Network Switch to provide Ethernet connection for device configuration and/or for a source device (only on UCX-4×3-H20).CATx Connect the switcher to an Ethernet Ethernet port to access the local network.HDMI Connect an HDMI sink (e.g projector) to the HDMI output port.RS-232 Optionally connect a controller/controlled device (e.g. projector) to the RS-232 port.Audio Optionally connect an audio device (e.g. active speakers) to the analog audio output port by an audio cable.GPIO Optionally connect a device (e.g. Relay box ) to the GPIO port.OCS Optionally connect an occupancy sensor to the OCS port.Power Connect the external power supply to the AC power socket and then to the switcher unit.
Powering the device is recommended as the final step.
UCX-4×1-H20Use IN1, IN2, IN3, or IN4 buttons for selecting the video source to the HDMI output.UCX-4×3-H20Use the OUT1, OUT2, or OUT3 buttons for selecting the video source for the specific output. Push OUT1 to select the video input for the HDMI OUT1port (OUT2 for HDMI OUT2 and OUT3 for HDMI OUT3). The sequence of each output button is the following: IN 1 OUT 1
Use the AUDIO OUT button for switching the audio source to the analog audio output. The sequence is the same as above.
Setting a Dynamic IP Address (DHCP)
- Keep the button on the right (AUDIO OUT on UCX-4×3-H20; IN4 on UCX-4×1-H20 model) button pressed for 5 seconds; all front panel LEDs start to blink.
- Release the button, then press it 3 times quickly. DHCP is now enabled.
Restore the Factory Default Settings
- Keep the button on the right (AUDIO OUT on UCX-4×3-H20; IN4 on UCX-4×1-H20 model) pressed for 10 seconds.
- If the LEDs blink fast, release the button, press it again 3 times quickly, then the device restores the factory default settings and reboots.Lock / Unlock ButtonsPress the left and right buttons together (within 100 ms) (IN1 and IN4 buttons in UCX-4×1-H20 model, OUT1 and AUDIO OUT on UCX-4×3-H20 model) to disable/enable front panel buttons; front panel LEDs blink 4 times when locking/ unlocking.
Software Control – Using Lightware Device Controller (LDC)The device can be controlled from a computer using the Lightware Device Controller software. The application is available at www.lightware.com, install it on a Windows PC or a macOS and connect to the device via LAN.
Firmware UpdateLightware Device Updater v2 (LDU2) is an easy and comfortable way to keep your device up-to-date. Establish the connection via Ethernet. Download and install LDU2 software from www.lightware.com where you can find the latest firmware package as well.
