Lightware MMX2 Series Quick Start Guide
Models: MMX2-4x1-H20, MMX2-4x3-H20
Introduction
Lightware’s MMX2 switcher series enhances and extends the possibilities of a meeting room, allowing participants to easily use their own devices such as laptops. The MMX2-H20 series models offer 4K signal switching with numerous control interfaces, including secure Ethernet, OCS sensor, GPIO, Audio, and RS-232 options. These devices are ideal for users needing cost-effective 4x3 and 4x1 HDMI-only switchers with audio de-embedding, GPIO, Ethernet, and RS-232 capabilities, without USB transmission.

Button Functionality
Source Selection:
- MMX2-4x1-H20: Use IN1, IN2, IN3, or IN4 buttons to select the video source for the HDMI output.
- MMX2-4x3-H20: Use OUT1, OUT2, or OUT3 buttons to select the video source for the corresponding HDMI output (OUT1, OUT2, OUT3). The sequence for each output button is: IN1 -> IN2 -> IN3 -> IN4.
- Audio Output: Use the AUDIO OUT button to switch the audio source for the analog audio output. The sequence is the same as for video outputs.
Configuration Functions:
- Setting a Dynamic IP Address (DHCP): Press and hold the rightmost button (IN4 on MMX2-4x1-H20, AUDIO OUT on MMX2-4x3-H20) for 5 seconds until all front panel LEDs blink. Release, then press it 3 times quickly. DHCP is now enabled.
- Restore Factory Default Settings: Press and hold the rightmost button for 10 seconds. If LEDs blink fast, release, then press it 3 times quickly. The device will restore default settings and reboot.
- Lock/Unlock Buttons: Press the leftmost and rightmost buttons simultaneously (within 100 ms) to disable/enable front panel buttons. Front panel LEDs blink 4 times to confirm the action. (IN1 and IN4 for MMX2-4x1-H20; OUT1 and AUDIO OUT for MMX2-4x3-H20).
Software Control and Firmware Update
The device can be controlled using the Lightware Device Controller (LDC) software, available for download from www.lightware.com. Install it on a Windows PC or macOS and connect to the device via LAN.
Keep your device up-to-date with Lightware Device Updater v2 (LDU2). Establish an Ethernet connection and download LDU2 and the latest firmware package from www.lightware.com.
Connecting Steps (Example for MMX2-4x3-H20)
- HDMI: Connect an HDMI source (e.g., BYOD laptop or room PC) to an HDMI input port.
- CATx (Ethernet): Connect the switcher's Ethernet port to a Local Network Switch for device configuration and/or source device connectivity (specific to MMX2-4x3-H20). Connect the switcher to an Ethernet port to access the local network.
- HDMI: Connect an HDMI sink (e.g., projector) to an HDMI output port.
- RS-232: Optionally connect a controller or 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 using 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.

Typical Application Diagram Description
The diagram illustrates a typical meeting room setup using the MMX2-4x3-H20 switcher. Multiple sources, such as two BYOD laptops and a Room PC, are connected via HDMI and CATx (Ethernet) to the switcher's inputs. The switcher is connected to a network switch via Ethernet. An HDMI output connects to a projector. Additional connections include RS-232 to a projector, analog audio to active speakers, GPIO to a relay box, and an OCS sensor to the occupancy sensor port. The setup shows devices placed under a desk and wall-mounted, demonstrating a comprehensive AV integration.
