Keep everything under control

MMX4x2-HDMI-USB20-L is an integrator-friendly, 4x2 matrix switcher for HDMI video and USB2.0 peripherals.

It has four HDMI inputs and two independent HDMI outputs, as well as a USB 2.0 layer that provides the switching of four external USB peripherals (such as webcamera, speakerphone, multitouch display, etc.) to four independent computers or laptops. As an additional benefit, the device offers full 480Mbps data speed over USB 2.0.

Bespoke USB functionality

Unique USB functions allow seamless integration in Unified Communication and small Video Conference rooms. The ”USB 5V Host Detect” function recognizes when a USB cable is connected and performs condition triggering for the Event Manager. For example, switch USB devices to the last connected USB laptop if configured accordingly. The ”USB 5V PWR Switch” turns ON or OFF peripherals’ 5Volt over the USB cable. As an additional benefit, the device offers full 480Mbps data speed over USB 2.0

”USB Disconnect” helps Cisco Room Kit Mini and Touch 10 control unit to switch between Webcam and Webex video conferencing operation modes. It also solves the problem when Cisco Touch 10 gets locked in USB webcam operation and touch buttons become unavailable.

Enhanced Room Control

MMX4x2-HDMI-USB20-L and built-in Event Manager automation makes the meeting room easy, intuitive and hassle-free: it detects powered computers, turns on the screen and camera, and prepares for the next call. Based on the specific configuration it allows auto-switch for USB and video signals. In other cases, USB may not follow video, according to the application.

Easy Cisco Integration

The MMX4x2-HDMI-USB20-L seamlessly integrates with Cisco Rooms, and also offers users unprecedented flexibility to utilize the Cisco Webex Room kits as a USB camera if they prefer to use a 3rd party video conference platform.
